2. 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. 3. A person is made up of matter. The matter in a person makes up their __mass__. 4. Some matter takes up a large space but has a __small__ mass. 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. 5. A person's mass does not change unless they lose matter. 6. A person’s weight is the measure of the __gravitational pull__ on that person. 7. To measure mass, we use a __pan balance__. 8. __Grams and Kilograms__ are the units used to measure mass. 9. __Volume__ is the amount of space that matter takes up. 10. Scientists use a __beaker or tall cylinder__ to measure volume. 11. Volume is calculated using the formula __L x W X H.__ 12. 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. 13. In order to find the volume of a liquid, you can pour the liquid into a container marked with milliliters. 14. The __3 physical properties__ of matter are mass, volume, and density. 15. Density __compares__ the amount of matter in an object to the amount of space it takes up. (Density = mass divided by volume.) 16. When you 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__. 17. To measure density you divide the mass by the __volume__. ||
