Test

Let's get studying! This website has helpful practice problems. Try the

"Observation, Inference, Classification" and "Density" tests.

Know how to...

• calculate density

• find volume of a cube and an irregular object

• find mass when density and volume are given

• use RT 1 Properties of the Earth

• use RT 10 Properties of Earth's Interior

• tell the difference between inferences and observations

• calculate rate of change

Side note: understand the density of liquids in a container. (liquids at a higher density sink to the bottom of a lake)

Also: Ice is less dense than liquid water, that's why it floats.
