Study 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)
