grade 3 science lesson by Mrs. Aisha

1. How is
matter
?measured

2. Measure
length

3. Matter is anything that has mass and takes up space.
Length is one property of
matter that can be measured.
Length is the distance
from one end of an object to
.the other end

4. To measure length, you can use
Metric ruler
Meterstick

5. You can use these lengths to compare objects.
For example, you can measure and
compare the length of
a pillbug and a beetle to determine
.which one is longer

6. The basic metric unit of length is
the meter (m). Shorter lengths are
measured in centimeters (cm) or
millimeters (mm).
There are 100cm in a meter.
There are 1000mm in a meter.
Longer distances are measured in
kilometers (km).
There . are 1000m in a kilometer

7. Measure
and
Compare
Volume

8. Another way to measure and
compare matter is by volume.
The volume is the amount of
.space the object takes up

9. Graduated cylinder is used to
measure the volume of a liquid.
Liter (L) is the basic metric unit for
measuring liquid volume.
Milliliters (mL) are smaller parts of
a liter marked by graduated
cylinders.
There are 1000 . milliliters in a liter

10. Graduated cylinder

11. You can measure the volume of a
solid, like rock, using water.
A rock keeps its shape in water.
A rock pushes water out of its
.way when it sinks

14. Measure
and
Compare
Mass

15. Mass of an object is the amount
of matter it has.
Solids, liquids, and gases all have
mass.
Balance is a tool used to measure
.mass

16. Gram (g) is a metric unit for
mass.
Kilograms (kg) measure larger
matter.
There are 1000 grams in a
kilogram
1kg = 1000 g

17. Measure and
compare
Temperature

18. You can different scales to measure temperature.
The Celsius scale is often used in
science.
Degrees Celsius is written as C .
The fahrenheit scale is often
used in everyday life in the
.united states

19. The outside temperature is
reported in degrees Fahrenheit.
Degrees Fahrenheit is written as
F.
.Sometimes both scales are used
