Guide Questions
1. A person
in outer space is said to be "weightless", but the person's mass doesn't
change. Why is the mass of the person in both places the same?
The
person contains the same amount of matter in both places.
2.What
tool is used to measure mass?
Use
a pan balance to measure mass.
3. What
units are used to measure mass?
Grams
or kilograms are used to measure mass.
4. What
is volume?
Volume
is the amount of space that matter takes up.
5. How
do scientists measure volume?
They
use a beaker or a tall cylinder
6. How
can you find the volume of odd shaped objects?
You
can find the volume of odd shaped objects by sinking them into water.
The change in water level gives the volume of the solid.
7. How
can you find the volume of a box?
Measure
the height, width, and length. Multiply the three numbers. Ex. H
= 2, L= 2 W = 2 (2 x 2 x 2= 8)
8. How
can you find the volume of a liquid?
You
can pour the liquid into a container marked with milliliters.
9.
Some matter takes up a large space but has a small mass. Give an example.
A balloon
can be very large, but be so light that it can float in the air.
A brick can be smaller than some balloons, but it has more mass.
10.
What is density?
Density compares the amount of matter in
an object to the amount of space it takes up. (Density = mass divided by
volume.)
11.
Compare the density of a balloon to the density of a brick.
The gas in a balloon has a low density. the density of the brick is much
higher.
12.
What are the three physical properties of matter that can be measured?
The
3 physical properties of matter are mass, volume, and density.
Be able
to calculate the volume and density of objects on the test.
(Volume
= l x w x h)
(Density
= mass divided by volume)

Investigation:
TLW investigate the
densities of some types of matter (E10-11) Materials Needed: 3 identical
plastic cups, raisins, breakfast cereal, pan balance.
TLW investigate measuring
matter using beakers and liquid (E12-13) Materials needed: beakers, water,
marbles)
