About Engineering is Elementary
Engineering is Elementary® (EiE) fosters engineering and technological literacy among
children. Most humans spend over 95% of their time interacting with technology. Pencils,
chairs, water filters, cell phones, and buildings are all technologies—solutions designed
by engineers to fulfill human needs or wants. To understand the world we live in, it is
vital that we foster engineering and technological literacy among all people, even young
children! Fortunately, children are born engineers. They are fascinated with building,
taking things apart, and how things work. EiE harnesses children’s natural curiosity to
promote the learning of engineering and technology concepts.
The EiE program has four primary goals:
Goal 1: Increase children’s technological literacy.
Goal 2: Increase educators’ abilities to teach engineering and technology to elementary
students.
Goal 3: Increase the number of schools and out-of-school time programs in the U.S. that
include engineering at the elementary level.
Goal 4: Conduct research and assessment to further the first three goals and contribute
knowledge about engineering teaching and learning at the elementary level.
The first product developed by the EiE program was the Engineering is Elementary
curriculum series. This curriculum, designed specifically for use in elementary school
classrooms, is research-based, standards-driven, and classroom-tested. For more
information about EiE, visit: eie.org.
In 2011, EiE began development of Engineering Adventures (EA), a curriculum
specifically for use in out-of-school time settings. EA is tailored to youths in 3rd through
5th grade. More information about EA can be found at: engineeringadventures.org.
In 2012, EiE began developement of Engineering Everywhere (EE). Like EA, this
curriculum is also designed for use in out-of-school time settings, but targets 6th
through 8th graders. More information about EE can be found on the next page and at
engineeringeverywhere.org.
Engineering is Elementary is a part of The National Center for Technological Literacy
(NCTL) at the Museum of Science, Boston. The NCTL aims to enhance knowledge of
technology and inspire the next generation of engineers, inventors, and innovators.
Unique in recognizing that a 21st century curriculum must include today’s human-made
world, the NCTL’s goal is to introduce engineering as early as elementary school and
continue it through high school, college, and beyond. For more information about the
NCTL, visit: nctl.org.

About Engineering Everywhere
The mission of Engineering Everywhere is to create engaging out-of-school time learning
experiences that positively impact youths’ attitudes about their abilities to engineer. Our
goal is to provide youth with personally meaningful and globally relevant challenges that
empower them to problem solve, think creatively, and learn from one another.
The main ideas that guide the developers of EE are listed below.
We believe youths will best learn engineering when they:
• engage in activities that are fun, exciting, and connect to the world in which they live.
• choose their path through open-ended challenges that have multiple solutions.
• have the opportunity to succeed in engineering challenges.
• communicate and collaborate in innovative, active, problem solving.
Through EE units, youths will learn that:
• they can use the Engineering Design Process to help solve problems.
• engineers design technologies to help people and solve problems.
• they have talent and potential for designing and improving technologies.
• they, too, are engineers.
As youths work through their engineering design challenges, they will have the
opportunity to build their problem solving, teamwork, communication, and creative
thinking skills. Most importantly, this curriculum is designed to provide a fun learning
opportunity!

What You Need to Know Before Teaching an EE Unit
Engineering is fun.
The EE team hears this from many OST educators and youths alike. Engineering is
really a way of problem solving—a way of thinking about the world—that is often very
fun and creative. Any time you need to solve a problem in order to reach a goal, you are
engineering.
There are no right or wrong answers.
There are often many great ways to solve the same problem. Not only is this a good
engineering lesson for the youths in your program, it’s a good life lesson.
You are a guide.
As the educator, it is your role to guide youths through these activties by encouraging them
to pursue and communicate their own ideas, even if you think they might not work. Every
problem has many possible solutions and multiple ways to reach them.
Ask questions!
Throughout the activities, you can ask questions prompting youths to share their prior
knowledge, predict what they might find, or remind them of criteria that will help them
as they engineer. Asking questions like these sets your youths up to succeed and feel
confident in their ability to engineer.
It’s okay to try it out!
It can be very helpful to try out the engineering challenge yourself—either beforehand or
right alongside the youths in your program as they work through the adventures. This can
help you understand the challenges they might face.
Support reflection
Each activity includes five to ten minutes at the end for youths to communicate with their
peers by sharing their work. This gives youths the chance to discuss new ideas, think about
their own work and the work of others, and reflect on what was learned. Group reflection
can help reduce competition by encouraging youths to support each other as they move
through the Engineering Design Process.

Engineering Notebooks
Youths will use the Engineering Notebook as directed in the
Activity Guide during every activity.
The Engineering Notebook is a central location for youths to
record their thoughts and ideas as they move through the unit.
Its pages guide youths through the Engineering Design Process,
pose questions, and prompts youths to reflect on their engineering
work. The time youths spend with their Notebooks during each
activity will allow them to create a personalized record of their
engineering learning.
Tips and Tricks for Teaching the Unit
Post a Daily Agenda
Giving youths a sense of the day’s activity will help them to plan ahead and manage their
time.
Facilitate Teamwork
Being able to work well in teams is an important skill for any engineer. You may want to
assign team roles to help youths if they struggle with teamwork. Possible roles include:
the notetaker, the materials gatherer, the tester, and the presenter.

Background
Biomechanical Engineering
Biomechanical engineering is a field that involves combining mechanical engineering and
biology. Biomechanical engineers use what they know about physics and biology to better
understand how physical forces impact living organisms. Biomechanical engineers develop
solutions to a broad range of problems including the improvement of safety equipment like
helmets, life jackets, and bulletproof vests.
Helmets
According to the Centers for Disease Control and Prevention, head injuries are the leading
cause of death in young adults and children. The number one thing adults can do to protect
children from injury is to make sure that they wear helmets whenever engaging in sports
or other activities (like riding a bike, scooter, or skateboard) that might lead to their heads
being bumped.
Helmets are generally constructed in three layers. The outer layer is usually a hard shell
made of fiberglass, the middle layer a crushable foam that absorbs shock, and the inner
layer a soft and comfortable liner. In addition, most helmets have some kind of strap system
to keep them in place. Depending on what the helmet will be used for, they may have other
elements attached to them, such as visors, ear pads, and face masks, which each provide
additional protection to the wearer.

Identify the Problem (5 min)
1. Welcome everyone to the engineering group. Let youths know that
engineers are problem solvers. To begin, you have an engineering
challenge that you’d like everyone to solve.
2. Hold up a plastic egg and introduce the egg as Humpty Dumpty. Ask:
• Does anyone know what problem Humpty Dumpty had in the
classic rhyme? He was sitting on a wall, fell off, and broke.
3. Explain that if the wall had been better engineered to hold him,
Humpty might not have fallen off and been saved. Explain that
youths will work in engineering groups to build a wall that their egg
can sit on without falling off.
4. Split everyone into groups of 2-3 and ask:
• What questions do you have before you begin working on
this problem?
5. Encourage questions about criteria (what the wall needs to do),
constraints (how they are limited), and how to evaluate success.
6. Answer the questions generated by the group by referring to the
bullets below and the Criteria and Constraints Chart. Be sure to give
groups the following information:
• Each group will get 40 index cards, tape, a ruler, and scissors.
• The scissors and ruler cannot be used as part of the wall.
• Groups need to create a wall that is at least 10 inches high.
• The walls need to be at least 2 inches wide and 4 inches long.
• Humpty-dumpty needs to be able to “sit” on top of the wall.
• Groups will have 25 minutes to work.
• The wall must hold the egg for at least 10 seconds.
• You can’t tape your wall to the table.
7. Post the Criteria and Constraints Chart. Help everyone realize
that criteria are things that the wall must do while constraints are
limitations on how the wall is made.
8. If the answers to some questions are not addressed by the Criteria
and Constraints Chart (such as: does it matter how our wall looks)
either decide the group doesn’t need to worry about them or add
them to the chart if the whole group agrees with on them.

Tip: The rhyme
youths will use to
help them time
how long the egg
remains on the wall
is written below:
Humpty Dumpty sat
on the wall / Humpty
Dumpty had a great
fall / All the king’s
horses and all the
king’s men / couldn’t
put Humpty together
again.
1. Pass out 40 index cards, masking tape, a ruler, and a pair of scissors
to each group.
2. Set the timer for 25 minutes and have groups begin building.
3. As groups work, pass around an egg so everyone can hold it and get
a sense of its mass.
4. As groups are working, ask questions like:
• How did your group come up with this design?
• Why do you think your design will work well?
5. Every 5 minutes, let groups know how much time they have left.
Test (15 min)
1. When time is up, have groups step away from their own work. Ask:
• What do you observe is the same about all of the designs?
Materials, shapes, etc.
• What do you observe is different about them? Different ways
of using the cards, different heights and widths, etc.
2. Point out that every group engineered a different solution. In
engineering, there are always many solutions to the same problem.
3. Tell groups they are going to watch as everyone tests their wall. After
placing Humpty on their wall, each group must recite all of the lines
to the Humpty Dumpty rhyme (which takes about 10 seconds).
4. Before testing, ask each group:
• Can you explain your design?
5. After each group tests, regardless of whether or not their wall met
the criteria, ask:
• How would you improve your design if you had more time?
Reflect (5 min

1. Gather everyone around the Engineering Design Process poster and
give everyone an Engineering Notebook.
2. Explain that engineers use a process called the Engineering Design
Process as a guide to help them solve problems. Ask:
• How did your group use these steps as you engineered your
tower? Encourage groups to link specific actions to specific steps,
for example: we used the Imagine step when we brainstormed.
3. Point out to youths that because they used these steps, they are
engineers! Let them know they will continue to use the Engineering
Design Process to guide their engineering work throughout the unit.
4. As a preview to the rest of the unit, ask:
• What other types of safety “gear” could you have engineered
to help Humpty be protected if he did fall? Helmets, padded
clothes, etc.
5. Let youths know that in the rest of the unit they’ll be thinking more
about materials and designs for helmets to protect things that fall.
6. Give youths a few moments to fill out My Engineering Profile, p. 4 in
their Engineering Notebooks. They will return to this at the end of the
unit to identify the engineering skills they have learned or improved.

1. Remind youths that engineers are people who design technologies
that solve problems. Ask:
• What kinds of problems do you think engineers solve?
Encourage youths to think big! Accept all responses.
2. Remind youths that they have already been engineers and have
designed a wall and thought about many other types of technologies
engineers have designed. Show youths your example helmet, or just
ask them to think about a helmet they have worn or are familiar with.
Ask:
• Are helmets technololgies? What problems do they solve?
Yes, helmets are technologies because they solve the problem of
protecting the skull and brain, so they are technologies.
• Why do you think engineering helmets is an important

Tip: Youths may not
have seen calipers
before. You may
want to demonstrate
how to use them by
measuring the size of
an item in the room.
Point out that when
you place the item
between the pinchers
of the caliper, the size
is indicated on the
opposite end of the
calipers.
Tip: When discussing
the size criterion for
the pasta packages,
you may want to draw
a link to the helmets
youths will design
later on. When making
helmets, engineers
often need to think
about how bulky their
designs are. People
don’t usually want to
wear helmets that are
very large, so creating
a sleek protective
design is important.
Youths will be thinking
about similar ideas
today when designing
their pasta packages.

3. Show youths the 5 foot tape mark on the wall. Explain that this is the
testing area. Have a volunteer hold the model you made at the 5 foot
mark and drop it. It is likely that the shell of the pasta will crack!
4. Ask:
• What types of impacts do you think a fall like this could have
on a human brain?
5. Lastly, go over the materials that youths have available to use to
protect their model brain (plastic sandwich bag, cotton balls, pipe
cleaners, bubble wrap, and craft foam).
6. Explain that while they can use whatever materials they would
like, their package designs cannot be larger than 3 inches in any
direction. Engineers often have to deal with this type of criterion;
using too many materials isn’t usually an effective use of resources.
7. Show youth the calipers and let them know they will use this tool to
measure the dimensions of their package designs.
Create (30 min)
1. Divide everyone into groups of 2-3.
2. Have groups turn to pages 4-5 in their Notebooks. They should use
these pages to guide them through the Engineering Design Process.
3. As groups work through the process, check in and ask:
• Which materials did you choose? Why?
• How do you think this design will protect the model brain?
4. When groups are ready, they can measure and drop their design
at the testing station. After testing, they should carefully look to see
whether or not the model brain was damaged. Have them record the
results of their test on the notebook page (Step 6).
5. After testing, encourage groups to improve their designs, either by
better protecting the model brain or by using fewer materials.
Reflect (5 min
1. Have everyone jot down one thing they learned from doing this
protection activity (Step 8). Ask for a few volunteers to share what
they wrote down.
2. Ask:
• What did our models teach you about protecting the brain
from a fall?
• How do you think using each step of the Engineering Design
Process helped you in this challenge?
• Which step do you think was the most valuable to your
group? Why?
3. Let everyone know that for the rest of the unit, they will use their
knowledge of how to protect fragile objects to engineer a safety
helmet that will protect another model brain and skull from damage.
4. Tell everyone that, in the next session, they will learn a bit more
about the brain and how helmets can be designed specifically for
different activities.

important function.
7. Tell youths that now they will participate in an activity to simulate the
symptoms of a severe concussion. Ask:
• Does anybody know what a concussion is? A concussion is a
type of brain injury caused by trauma.
• Can anybody name a symptom of a concussion? Accept all
answers.

symptoms. They will then put on a pair of goggles designed to
simulate some symptoms of a concussion, spin around five times,
and complete the obstacle course again.
Tell youths they should focus on how the concussion symptoms
affect their ability to complete each task.
Bring youths over to the obstacle course and explain each of the
tasks they must complete. Point out the brain toss and basket
toss activities require a volunteer to help with the completion of
the challenge. Tell youths that volunteers will rotate through these
positions, so everyone can complete the obstacle course.
Time youths as they complete the obstacle course without the
concussion goggles. Have youths record their times on p. 7 of their
Engineering Notebooks.
Have youths complete the obstacle course while wearing the
concussion goggles. Make sure youths spin around five times before
the timer starts and they begin the course. Have youths record their
times on p. 7 of their Engineering Notebooks.
Reflect (10 min
1. After youths complete the obstacle course, have them reflect on the
differences between their two different runs. Ask:
• How did you feel when you spun around and wore the
concussion goggles? Accept all answers. Youths may note they
felt dizzy, had blurred vision and poor depth perception.
• What was difficult about completing the course wit
concussion symptoms compared to your first run? Harder to
walk the line, more difficult catching/aiming, more disoriented in
general.
• What sort of tasks would be difficult to complete in you
daily life if you had these symptoms permanently? Accept all
answers.
2. Explain to youths that someone with a serious concussion can have
symptoms like blurred vision, dizziness, distorted depth perception.
These were some of the symptoms they experienced during the
obstacle course. Additionally, even mild concussions can cause short
term memory loss, confusion, nausea, vomiting, and headaches,
which they did not simulate today.
3. Let groups know that during the next session they’ll be able to begin
engineering their own helmet designs to protect against concussions.

6. Kids will test their helmets by observing whether a paint ball inside the helmet breaks
when the model head is dropped. Set up the Drop Test station:
• Tape a plastic tube across the top of a door or another high spot in the room.
• Attach one end of the fishing line to the base of the model head
• Feed the other end of the fishing line through the plastic tube you have secured to the
door or ceiling.
• Pulling on the free end of the string should raise the model head.
• Attaching a washer or handle to the string makes it easier to pull.
• Tape the hat to the model head.
7. Do a test to make sure the paint balls will actually break when there is no helmet placed on
the head.
• Tape a bag holding a paint ball to the top of the head and hat.
• Pull on the string until the head is raised as high as it can go.
• Drop the head.
• If the paint ball is smashed, you can leave the set-up as-is.
• If the paint ball is not smashed, you should add some weight to the model head. Screw
the cap off of the bottom and insert golf balls, or another weight.
Tip: Feel free to remove the hat and attach the paintball to the model head if it
becomes to cumbersome.
Notebook Pages for Activity 3
In the late 1800s there was a manufacturing company
called Bullard that sold mining equipment to gold and
copper miners. In 1919, their first safety helmet was
patented. The Bullard helmet was based on a helmet
that the CEO had worn as a soldier during World War I.
Early 1900s Hard Hat
The original safety helmet was made out of steamed canvas, glue, a leather brim, and black
paint. Most importantly, there was a suspension device built inside that held the “bucket”
portion of the helmet off of the head.
In 1938, Bullard designed and manufactured the first aluminum hard hat, which was
very durable and lightweight for the time. There are disadvantages to aluminum, though.
Aluminum helmets conduct electricity, for example. Later helmet designs have used
fiberglass and plastic as materials.
Today’s Yellow Hard Hat
When you mention hard hats, many people
imagine a yellow, plastic version. This common
design does have many features that make it
desirable to use. Because it is made of plastic
ti is lightweight, durable, and does not conduct
electricity. The shape has also been designed
to offer good movement. The interior contains
a shock liner and padding to make the helmet
comfortable. New versions include vents that help
keep the user cool.

Head injuries are one of the biggest risks of
playing football. Because players run at high
speeds and collide into one another headfirst, injuries can be severe. Wearing specially
designed helmets can help reduce the risk of
injury.
There were occasional attempts in the early 1900s to have
players wear helmets, but the idea never stuck. In the late
1930s, for example, Detroit general manager and coach
Jack Adams made helmets mandatory for all Wings. One
by one, the players abandoned them, saying they were too
confining or uncomfortable.
Leather helmets were the first type of helmet used
by football players. These helmets were soft and
offered a very thin layer of padding. The helmets
were so soft and flexible that they could be folded
up and put in a player’s pocket.
In the 1930s helmet designers began treating the
leather so that it was harder. More padding was
also added.
1980s Hockey Helmet
Perhaps the most influential spokesman for helmets was Red
Kelly, the longtime Wings defenseman. Kelly began wearing
a
helmet shortly after being traded to Toronto in 1960. “Kelly plays it safe,” proclaimed a safety
brochure distributed in Canadian schools. By 1964, about 200,000 players in the Toronto
Hockey League were wearing the mandated helmets.
Addition of Graphics
In the 1940s, teams began placing colored graphics
on the outside of leather helmets. The first team to do
this was the Los Angeles Rams. They painted blue and
yellow rams horsn on each side of the leather helmet.
Graphics continue to be used by most teams today.
On June 1, 1979, the NHL began requiring anyone
entering the league after that date to wear a helmet.
Existing players could continue to go hatless if they
wished. The last player to play without a helmet in the
NHL was Craig MacTavish of the St. Louis Blues during
the 1996 to 1997 season.

Modern Football Helmet
Plastic Helmets
The National Football League introduced plastic helmets in the 1940s and 1950s. Plastic
helmets are still used today, though the designs have changed drastically and helped improve
the comfort and safety of the helmets. Some of the helmets used today even containing
electronic monitors that register the impact sustained by the helmet and can alert players
and coaches about potential concussions and brain
damage.
The first helmets widely worn in the NHL were molded plastic helmets imported from Europe.
In the early 1970s, General Electric produced a helmet made of synthetic material called
Lexan. This helmet also featured a suspension system
that kept the head from contacting the outer shell.

History of Hockey Helmets

Like many other athletes, bicyclists first used leather
helmets. By the 1970s some cyclists had taken to wearing
hockey or mountaineering helmets since no hard helmets
specifically designed for cyclists existed. Cyclists saw the
need for head protection, but it was difficult to find light
weight helmets that did not obstruct views and offered
ventilation.
Leather Helmets
Around 1973, a company called Mountain Safety Research,
introduced a modified mountaineering helmet that many cyclists
used. The helmet used cloth webbing attached by side clips
to provide impact absorption. They later added foam inserts
between the webbing straps. The next year, a company called
Bell introduced the first helmet designed from scratch specifically
for bicycling. It used foam as its impact-absorbing material, and
had tapered ventilating inlets, as do most other bicycle helmets
made since.
Modern Bicycle Helmet
Modern Helmets
There are three main types of modern bicycle helmets:
Hardshell: This type of helmet has a hard plastic shell designed to resist penetration by
pointed rocks, curbs, etc. Most skate-style helmets are still made this way.
No-shell: For a short while, in the late 1980s, bicycle helmets were made from an expanded
polystyrene shell covered with thin cloth. This helmet weighed less than other helmets, but
questions arose as to whether the polystyrene might snag on rough pavement during a fall.
This could cause brain and neck injury due to
head rotation. Also, such helmets would
often break apart on impact.
Thin-shell: This type of helmet is covered with a
thin plastic shell. It provides a smooth surface to
avoid snagging on rough pavement, and helps to
hold the helmet together on impact. In
high-end helmets with big vents, reinforcing of
plastic, nylon or more exotic materials is molded
inside the expanded polystyrene. Most helmets
made and sold since 1990 are thin-shell helmets.

History of American Football Helmets
On January 13, 1968, Minnesota’s Bill Masterton hit his
head on the ice and never regained consciousness. His
death remains the only on-ice fatality in National Hockey
League history. Like almost all pro players then, Masterton
wasn’t wearing a helmet. Although many players in the early
days of the sport wore hats, they were just trying to keep
their heads warm, not protected.

Create Your Safety Helmet
Activity
Guide
Youths will understand:
•
creating and testing their helmet designs will give them information that will help them
fine-tune and improve their final design.
How to Test the Helmet Designs (10 min)
1. Remind everyone that their challenge is to engineer a helmet that will
protect a model head from damage. Show groups the plastic model
head at the Drop Station you prepared. Let them know this is the
head they will be designing a helmet for.
2. Guide the group to think about criteria and constraints for their
helmets. Ask:
• What are some things our helmets should do? Protect the
head.
• What is important to you in a helmet design? It should look
nice, it should be comfortable, it might need to be cheap, etc.
3. Explain to youths that the helmets they are engineering will be used
in a sport where there is a high chance of the wearer falling headfirst. There are a few criteria and constraints that have already been
set for their designs and they can choose to add others to the list if
they would like. Post the Criteria and Constraints Chart. Ask:
• Is there anything you’d like to add?
4. Call attention to the criterion that states that the helmet must be removable.
Explain that students will build their helmets and then move it to the plastic
one for testing. They can start building the helmet on a group member's
head, and check the sizing using the plastic head.
Tip: Groups may
need to rest their
helmets on a cup or
other container when
weighing. Review how
to tare the scale to
zero before weighing
the helmet.

Engineering Everywhere
5. Have everyone turn to Helmet Scoring Sheet, pp. 14-15. Tell them
that this scoring sheet describes how they will evaluate their helmet
designs. Review each of the scoring categories on the sheet, by
explaining the procedures associated with each score:
• Demonstrate how to measure thickness with the caliper.
• Demonstrate how to weigh the helmet with the gram scale.
• Place one paintball inside a small plastic bag and seal it (Double
bagging is recommended). Tape the bag to the top of the model head.
•
Demonstrate how to test for safety by dropping the model head
you prepared earlier. Pull on the fishing line until the head is
raised all the way, then release.
• Explain that the helmet is considered “safe” if it protects the paint
ball from damage.
• Review the price list found in the notebooks on page 12.
6. Allow youths to ask any other questions that have come up.
16
Put a Lid on It
Plan and Create (35 min)
1. Divide everyone into groups of 3-4 (up to 6 groups will work best).
2. Tell youths to turn to pp. 8-11 in their Engineering Notebooks.
Explain that here they can review the history and design of lots of
types of helmets, which they can use to inspire their own designs.
3. Give groups some time to plan their helmet. They can record
thoughts on their Plan Page, p. 13. Once groups show you a
completed Plan Page, have them go to the materials table to collect
their supplies.
4. As groups work, circulate throughout the room, encouraging groups.
Ask questions like:
• Can you tell me about your design?
• What part of your design do you think will work well?
• What do you predict will happen when you test your design?
• What part of your design might need improvement?
5. When groups are done creating, they should weigh and measure
their completed helmets and record their scores on their Helmet
Scoring Sheet, p. 14. They should also calculate and record a total
cost on their Helmet Scoring Sheet, p. 15. When those scores have
been recorded, groups should bring their helmet to the safety testing
station.
6. Every five minutes, let everyone know how much time they have left.
Safety Testing (15 min)
1. Let groups know it’s time to test the safety of their helmets!
2. Have groups begin testing their own helmet designs, rotating so
each group has a chance. Assist groups as they tape a paint ball
to the top of the model head (double bagged), put on their helmet
design, pull the nylon fishing line, and drop the head.
3. Students should gather around and observe each other’s testing
procedures and respectfully share their thoughts about results.
4. The testing group should record the results of their safety test on
their Helmet Scoring Sheet, p. 14 of their Engineering Notebooks.
5. Let groups know that they will have a chance to Improve their
designs next time, so they should keep track of what is working
and what parts of their designs need improvement. Encourage this
thinking by asking questions like:
• Is your design working like you Imagined it would?
• What is working well about your design?
• What parts need improvement?
• What changes might you make tomorrow?
6. When safety testing has been done for each helmet, enlist
everyone’s help in cleaning up the space. Be sure to save the helmet
designs for use next time.

Introduction (5 min)
1. Review where groups are in the process of the design challenge.
Ask:
• How far in the Engineering Design Process do you think we
got last time? We Tested our designs.
• What information can you use from last time to help you
improve your helmet designs?
2. Explain that today groups are challenged to Improve upon their
helmet by decreasing their total assessment score by at least one
point.
3. Have groups reflect back to the challenge criteria. Ask:
• Which helmet properties do you think are the most
important? Helmet must protect the head. Youths may also say
that the helmet should be cheap or comfortable. Guide youths to
think about which properties they may want to focus on for their
helmet improvements.
4. Tell groups that they will have access to additional materials to
complete their improved helmet.These additions include:
• Groups will be able to use duct tape to help hold materials
together.
• Groups will be able to decorate their helmets with printed
duct tape.
5. Show youths that the prices of the new items have been added to the
bottom of the Price List and have youths add those items to the their
own Price Lists in their Engineering Notebooks.
Improving Helmets (45 min)
1. Have youths look at Improved Helmet Plan, p. 16 in their Engineering
Notebooks. Explain that they should use the page to record their
improved design and calculate the cost of their materials.
2. Give groups a few minutes to brainstorm and record a plan for how
they will improve their helmets.
3. After groups have recorded their improved designs in their
Notebooks, they can go to the materials table and begin working.
22
Put a Lid on It
4. As groups are working, ask questions like:
• What did you change about your design and the materials?
• Why do you think the improved design will work better?
• What do you predict will happen when you test your design?
5. Once their improved designs are complete, groups should measure
and score the new helmet in terms of thickness, weight, and cost just
as they had done the previous day.
6. Then, all groups should test the helmet for safety by using the paint
ball drop test. Scores the Improved design should be recorded on
their Improved Helmet Scoring Sheet, pp. 17-18 of their Engineering
Notebooks.
Reflect and Share (10 min
1. Gather the group together and have each team describe the
improvements they made to their helmet designs and how today’s
scoring differed from yesterday’s.
2. As groups share, ask questions like:
• What parts of your helmet did you change?
• How do you know how successful your improvements were?
• If you had more time or other materials, what else might you
do to Improve your helmet design?
3. Remind everyone of the value of trying things more than once and
how important the Improve step is. Ask each group to share some
new things that they learned about making helmets now that they
have spent a second day on the process.
4. Let groups know that next time they will share their work with the
other groups, and play technology jeopardy, time permitting.

engineer will help
youths become more
comfortable with it!
If youths are having
trouble understanding
what it means to
engineer something,
let them know that
words like invent,
design, and improve
can have a similar
meaning.
Introduction (5 min)
1. Tell youths that they will use what they have learned to think about
the many other things that engineers design.
2. Guide youths to think about the word technology. Ask:
• What do you think technology is? Encourage all answers and
examples.
3. Let youths know that you have a definition of technology you’d like
to share. Write the following on the board: Technology is any thing
that is human made that solves a problem or fulfills a desire.
4. Ask:
• Is there anything about this definition that surprises you

Technology Jeopardy (30 min)
1. Let youths work in groups of 3-4 for Jeopardy.
2. Project the Technology Jeopardy game or use the paper-based
version.
3. Play the game by allowing a group to pick a question. The first group
to raise their hand and correctly answer the question will “win” the
associated points.
4. If you are using the paper-based version with a chart on the
board, erase or ‘X’ out the point value when the question has
been answered. The electronic version will automatically gray-out
questions that have already been used.
