•HOLIDAY!
•
8 Sept: Measurement Notes.
9 Sept: Measurement Investigation- students use science tools to complete a packet. Debrief
investigation. If time, KAHOOT review for tomorrow's test
10 Sept: TEST!! Safety, 3 types of investigations & measurement test. (open note, open lab
sheet test)
11 Sept: review yesterday's test. ASSIGN LAYERS OF THE EARTH project. Sorry parents; this
comes from the district, not us. It is an expectation that the student builds the project with minimal
parent help and minimal cost.
RUBRIC Project due Monday 8/21

Dimensions, quantity, or capacity as
ascertained by comparison with a
standard

Prefixes
Kilo____ = 1000 times
Suffixes
___meter
(distance)
Centi___ = 1/100
___liter (volume)
Mili____ = 1/1000
___gram (mass)
It is based on multiples of 10!

a system of ordered
marks at fixed
intervals used as
a reference standard
in measurement
Intervals of 1
10

What is the interval of this scale?
Interval
is…..
30
2
units
20

What does MASS (g)
measure?
Measures how much matter is
in an object.
How is it measured?
It is measured with a Triple Beam Balance
Milligrams, Grams, & Kilograms
9
Tips on using the
Triple Beam Balance
•Move the 100s first, then 10s, then 1s.
•Make sure the 100s and 10s slider is in
a grove.
•Use the tip of a pen or pencil to move
the small 1s slider.
•Last make sure the lines are even!
10
A balance is ready to use
when it is zeroed out!

15
What does Force (N) measure?
Push or Pull! Measures how much
effort it takes.
How is it measured?
Measured with a spring scale
Measured in Newton's
16
Too High!!!
JUST
RIGHT!!
Too Low!!!
Like the Triple beam balance,
make sure the spring scale reads
zero before you use it!!
17
3.4 N
(What is the
scale?)
18
1.3 N
(careful
with the
scale)
19
14.4 N
Scale is 0.4!!!
2.0 divided
by 5 units =
0.4
20
5.8 N
21
How
much
force is
required
to pull the
stool?
12.8 Newtons
22
What does Distance (m) measure?
It measures how long something is
or how far it is.
How is distance measured?
It is measured with a ruler or meter stick
using millimeters, centimeters, &
kilometers.
23
When measuring Length
Remember to:
• Make sure you know the units
of your ruler or measuring
instrument.
• Identify the scale
• Line up the object up at the
zero mark
24
5 cm
