Which of the following is the best example of using appropriate safety equipment during a field investigation?

• Wearing flip-flops

• Eating snacks during the investigation

A student reads that oil floats on water. Based on this information, what can the student infer about the density of oil compared to water?

• Oil is denser than water.

• Oil has the same density as water.

• Oil is less dense than water.

• Oil and water have no density.

Quick Write: A student observes that a balloon filled with helium rises in air. Using your knowledge of density, explain why this happens.

• Helium is denser than air, so the balloon rises.

• Helium is less dense than air, so the balloon rises.

• Helium and air have the same density, so the balloon stays in place.

• The balloon rises because it is heavier than air.
