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

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

 The size of an object

 The average of a set of data

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

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

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

 How tightly something is packed together

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

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

 How do spring scales measure weight?

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

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

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

 Name two ways you can increase the buoyant force.

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

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

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

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