LESSON 4 Mass vs. Volume: Proportions and Density
Mr. Moreno's class is experimenting with things that sink and float.
The students do an experiment to find out whether a different amount of the same material has a different density, 
. They measure the mass and volume of 3 different amounts of clay, record their data in a data table, and graph their data. Then they do the same thing for different amounts of steel to see whether they get similar results for different materials. You will do the same in the lab that follows. You will find the mass and volume of 3 steel balls and 3 lumps of clay that are about the same size as the steel balls.

- Discuss with your group how you will do the experiment. Then draw a picture that shows what you will do. Be sure to label the variables and include all the equipment you will use.
