2.  The measure of the force of gravity pulling on an object

3.  The amount of “stuff”, or matter in an object

4.  The size of an object

5.  The average of a set of data

6.  The number that occurs most often in a set of data

7.  The floating force pushing up on an object in the water

8.  When an object is placed in the water, the water is pushed aside. The water pushes back on the object, creating the buoyant force.

9.  How tightly something is packed together

10.  What were three things that caused everyone’s spring scales to be calibrated differently?

11.  How are mass and weight different? Why does your weight change on the moon, but your mass does not?

12.  How do spring scales measure weight?

13.  Explain why some shapes caused the clay to float, and others caused the clay to sink.

14.  Why doesn’t the clay’s weight change when you change its shape?

15.  Why did the large fishing bobber have the most buoyant force pushing back on it?

16.  Name two ways you can increase the buoyant force.

17.  Why did all of the large cylinders displace the same amount of water?

18.  How could you use displacement to compare the volume of two objects?

19.  Why do all of the cylinders seem to “lose weight” under the water?

20.  How much did a large cylinder full of water weigh? How does this relate to whether or not a cylinder floats or sinks?
