• a conductor of electricity

4. Sugar, a soluble substance, ___________ in water, breaking down into smaller and smaller pieces.

• melts
• freezes
• dissolves
• evaporates

5. A ping pong ball floats in a pool of water, meaning it is ___________ water.

• more dense than

• soluble in water
• a good electrical insulator
• has no mass

7. Why is D an incorrect answer?

• D says that powdered drink mix is solid, but it is actually a liquid.
• D says that sand is insoluble, but it actually dissolves in water.
• D says that lamp oil sinks, but it actually floats in water.

8. Which of the following is a correct justification for selecting B as the answer?

• The answer is B because sand sinks in water.
• The answer is B because lamp oil sinks in water.
• The answer is B because the physical states are correctly identified and all of the substances dissolve in water.

9. Saralynn is collecting objects during a physical property scavenger hunt for her online science class. The items she collected are shown below. Her teacher asks her to classify objects into more than one group. She can classify the items into two different categories using --

• relative density.
• solubility.
• physical state.
• conductivity.
