Students perform an experiment and record their observations. The results are shown in the chart below.

What are the students most likely observing?

• Sinking and floating of objects

• Objects that are not magnetic

• Solids, liquids and gases

• Objects with the greatest density

A student reads the directions on a jar of all natural peanut butter.

Why do the directions suggest stirring the peanut butter?

• Oil from the peanuts separate from the mixture because it is less dense.

• Oil from the peanuts separate from the mixture because it is more dense.

• Salt from the peanuts cause the mixture to separate.

• Water from the peanuts cause the mixture to separate.

The picture below is an electrical wire.

What is the most reasonable answer for using copper in an electrical wire?

• Copper is a good insulator of electricity.

• Copper is magnetic.

• Copper is a good conductor of electricity.

• Copper is shiny.

Students sort materials into two groups. Group 1 contains a metal fork, a safety pin, and metal nail clippers. Group 2 contains a penny, a compact disc, and a soda can.

Which physical property of matter did the class use to sort the materials?
