Bar codes
~Miah and Ana~

Nearly every item that you purchase from a grocery store, department store and
mass merchandiser has a UPC bar code on it somewhere. (Marshall Brain, 2015)

Joseph Woodland and Bernard Silver on October 7, 1952.

Bar code was not commercialized until 1966

A barcode scanner is the most essential piece of equipment in any retail
environment. (

Dear Substitute,
Thank you for covering my class.
I will be out for the next four days. Here are the lessons for the next two days.
This project will be started and completed in class. I suspect that this project will take the
students 4 class periods to complete.
I have three classes. My first and second classes are 6 grade humanities. My 4 period
class is STEM integration with 6 Graders.
3/19/2015 -3/20/2015
Day 1:
What invention is the best?
Microwave, Bar Codes, or Satellites
th
th
th
Objective: Students will understand the social and scientific significance of each item.
They will then pick which item is the best invention that impacts the United States today.
Step 1: (This will take about 90 minutes)
Create a shared Google Document.
Conduct research on each item.
Complete this list of questions for each item.
1.
You will put 4-6 bullet points with APA citations in each of these boxes.
2.
You will separate the work so that each team member is helping to accomplish the goal.
3.
You will review how to cite in APA>
4.
Please put your list of websites under your table.
What were the inventions
needed to help make this
possible?
Microwave


What are the impacts
of this invention on
society?
Percy Spencer
microwave oven
was invented by
accident by a man
named percy
spencer( 2007,SME
CC)
Microwaves are
basically extremely
high frequency
radio waves, and
are made by
various types of
transmitter.

People found
a way to heat
up food using
a microwave.

“Microwave
ovens use radio
waves at a
specifically set
frequency to
agitate water
molecules in
food”(Mathilde
Wolpert).
Nearly every item that
you purchase from a
grocery store,
department store and
mass merchandiser
has a UPC bar code on
it somewhere.

How does this technology
work?

Microwave ovens
use radio waves
 molecules get
increasingly
agitated they
begin to
vibrate(2002,
CERN)

invented as an
accidental byproduct of wartime

The last digit of the
UPC code is called
a check digit
Each time the
scanner scans an
item, it performs
his calculation.
They are used to
encode information
such as product
numbers, serial
numbers and batch
numbers.


Bar Codes


Our world has
turned around
since barcodes
have been
around( 2015,
LinkedIn
Corporation)


Satellites

prototypes( 1996-

National Geographic
Society).
Sputnik 1.(1996National Geographic
Society)

A satellite is a moon,
planet or machine that
orbits a planet or star. For
example, Earth is a
satellite because it orbits
the sun.



“As you can see
satellites are an
integral part of
everyday life
They have
thousands of uses
and perform it
without most ever
being seen
Just think now
how many satellite
dishes you have
seen on top of a
house and that's
just one aspect

gives a birds eye
view of what is
happening(2014,NA
SA)

Before satellites, TV
signals didn't go very
far(2014,NASA)
A satellite works by
receiving radio signals
sent from the Earth and
resending the radio
signals back down to
the Earth(2014,NASA)

Step 2:
As a group, hold a meeting to discuss which of the items that you have research has had the most
impact on human society.
As a group, create a Google Document of 11 or more Slides that will convince us that your item
is the best invention.
1.
Start Slide one with a thesis statement (Respond to the prompt – Which invention is the
best?) (1 Slide)
2.
Provide 2 scientific reasons on why it is the greatest invention (4 slides in total with
evidence in APA)
3.
Provide 2 social/humanities reasons on why it is the greatest invention (4 slides total with
evidence in APA)
4.
Provide 2 reasons why the other two inventions are not as good as your invention. (2
Slides)
5.
Conclusion slide that explains it. All.
Step 3:
Students take turns in groups: microwaves, satellites, and bar codes.
Rubric:
STEM Gradebook:
1.
Students create a PowerPoint that has a workable thesis that replies to the prompt, 4
slides regarding the scientific reasons, 4 slides for the social/humanities reasons, and 2 of why
the other inventions are not as important.

CCSSL.01.1.19 6-8.WHST.1 Write arguments focused on discipline-specific content. a.
Introduce claim(s) about a topic or issue, acknowledge and distinguish the claim(s) from
alternate or opposing claims, and organize the reasons and evidence logically. b. Support claim(s)
with logical reasoning and relevant, accurate data and evidence that demonstrate an
understanding of the topic or text, using credible sources. c. Use words, phrases, and clauses to
create cohesion and clarify the relationships among claim(s), counterclaims, reasons, and
evidence. d. Establish and maintain a formal style.
