Statement of Inquiry/IB Trait
STATEMENT OF INQUIRY: Humans explore the
relationships among interacting variables and use evidence to
impact communities and find functional solutions using
scientific and technological advances.

We’ll watch as Tim and Moby explain the SI (metric)
system of measurement.
I need 2 volunteers…
• I need two scholars to come to the front of the room
for a short demonstration.
• It is your job to measure the distance from one wall
to the other using the ruler in centimeters and report
it back to the class when you are finished.
Guiding Questions
• Are there any other units
that would be better to
measure the distance from
one wall to the other?
• What if we were measuring
the distance from Arlington
to Dallas? Would we use
centimeters or meters?
• What is the common theme
amongst all the units we’ve
talked about so far?

What are SI Units?
• Scientists, and most of the world,
use the International System of
Measurement – SI Units. {Also
known as the metric system.
• SI Units are a worldwide system of
measurements that scientists have
agreed to use in their work.
• This means that scientists all over
the world in every country and in
every language, use the SI system
of measurement!
• The United States is one of the only
countries who does not use the
metric system as their standard
measurements.

Base Units
• Each type of measurement in SI
has a base unit.
• Such as meter for
length/distance or seconds for
time.
• Let’s take a look at the most
common base units we will use
in this class and what they
measure.
Length/Distance
• Length is the measurement of
how long something is.
Distance is the measurement
of how far something is.
• When scientists want to
measure the length or the
distance of something,
they’re going to use the base
unit, meter.
• The symbol for the meter is
(m).
– Lowercase for base units!
Mass
• Mass is the amount of
matter in an object.
– It is not the same as weight!
• When scientists measure
mass, they use grams.
• The symbol for the gram is
(g).
Volume
• Volume is the amount of
space an object takes up.
• When scientists measure
volume, they use liters.
• The symbol for liters is (L).
– The only base unit whose
symbol is uppercase!
Temperature
• Temperature is a measure
of the average kinetic
energy of particles.
• When scientists measure
temperature, they use
degrees Celsius.
• The symbol for the Celsius
is (°C).
Time
• We can think of time as the
duration of an action or
specific events of the past,
present, and future.
• When scientists measure
time, they use seconds.
• The symbol for the seconds
is (s).
Think-Pair-Share
Why do scientists think that using the metric
system is easier than other systems of
measurement?

SI Prefixes
• A prefix is a letter or word
that’s placed in front of
another word to give it
meaning.
• In SI Units, prefixes are
added to base units to
create larger and smaller
units for that quantity.
Adding a Prefix to a Base Unit
• To indicate measurements much larger or much smaller than
the base unit, you add a prefix to the base unit label.
– For example, adding milli- to liter is a milliliter.
– Adding kilo- to meter makes a kilometer.
• SI Units are all powers of 10, that means that all prefixes
indicate units that are 10 times larger, or smaller than the unit
on either side of it.
– Milli- always means 1/1000 of a base unit. That means that a milligram
is 1/1000th (fraction) the size of a gram.
– Kilo- always means 1000 times the size of the base unit. That means
that a kilogram is 1000 times larger (multiple) of a gram.
Adding a Prefix to a Base Unit
• There are way more prefixes
than you will ever need to
use in your life.
• However, there are six
common prefixes that you
do need to know.
• We can look at these
prefixes in the form of a
ladder.

How do we remember these
prefixes!?

• DON’T FORGET TO LABEL YOUR UNITS!

18 min
Numbered Heads/Jigsaw
• Everyone in your table group
will need to number off from 1-4
(it’s okay if there are duplicate
numbers in a table group.
• All the number 1’s will work on
box 1 of the guided notes.
• All the number 2’s will work on
box 2 of the guided notes.
• All the number 3’s will work on
box 3 of the guided notes
• All the number 4’s will work on
box 4 of the guided notes.
18 min
Numbered Heads/Jigsaw
• Your job is to identify the best
unit for each example
measurement.
• You must choose the correct
base unit and prefix.
• Some of them might just be the
base unit with no prefix!
18 min
Numbered Heads/Jigsaw
• After 3 minutes, scholars will get
together with other 1’s, 2’s, 3’s,
and 4’s from other table groups
to compare and discuss answers.
• When you have agreed on the
correct units, you will take your
information back to your table
group and share for 5 minutes.
3 min
Numbered Heads/Jigsaw
• Silently begin working on your
assigned questions. Don’t forget
to explain why.
• Do not work ahead on any other
questions in other boxes.
• You will have 3 minutes to
complete your questions.
• If you need any references of

materials at the front of the
room.
4 min
Numbered Heads/Jigsaw
• All of the 1’s meet in the front
right corner of the room.
• All the 2’s meet in the back right
corner of the room.
• All of the 3’s meet in the front
left corner of the room.
• All of the 4’s meet in the back
left corner of the room.
• Discuss your units and come up
with a consensus about what
units to use to measure the
quantities.
5 min
Numbered Heads/Jigsaw
• All scholars should go back to
their table group.
• Each scholar will share out for
about a minute about the
quantities in their box while
their group members take notes.
• By the end, all scholars should

Independent Practice
• Silently work on the worksheet over
SI Units.
• Fill in the blank boxes (quantity, unit,
symbol) of the top section based on
the information already provided to
you.
• Explain the meaning of the prefixes in
the bottom table –
• Ex. Kilo- is 1000 times larger
