Science Air Test

A weather forecaster predicts that there will be high humidity and high levels of precipitation in an area. How does humidity differ from precipitation?

• Humidity is water that falls as a liquid, and precipitation is water that falls as a solid.

• Humidity is water that falls as a solid, and precipitation is water that falls as a liquid.

• Humidity comes from gaseous water mixed in air, and precipitation is liquid or solid water.

• Humidity describes the amount of air pressure in the atmosphere, and precipitation describes the type of cloud.

Michael rides a bike made from Company A. Luis rides a bike made by Company B. How can Michael and Luis determine in a scientific way whose bike has tires that last longer?

• Read information about the tires from each manufacturer.

• Ask ten classmates who ride each bike which tires last longer.

• Each student should ride their own bike for 25 days on different surfaces, then compare tires.

• Each student should ride their own bike for 25 days on identical surfaces, then compare tires.
