Density for 8th Grade

As part of your review you will be accessing the following game:

Select "MYSTERY" on the upper right-hand corner.
Measure the MASS using the balance.
Measure the VOLUME by dragging the block all the way down the tank and calculating the displacement.
After finding all the measurements select "SHOW TABLE" and find out what that block was made of.

Have fun!
