Curated OER
Warm and Cold Air
Students conduct an experiment to discover what happens to air when it is heated or cooled, discover that wind moves from a high-pressure area (an area of sinking air) to a low pressure area (an area of rising air).
Curated OER
Warm Air versus Cold Air
Students discover that warm air takes up more space than cold air. In this science lesson, students perform 4 experiments using balloons to determine that the molecules of warm air are more spread out than those of cold air.
Curated OER
Hot and Cold Air
In this hot and cold water worksheet, students use hot and cold water to experiment and see what happens when the two mix together. Students also answer 7 questions.

Temperature and the Density of Air
Here is a hands-on activity in which junior scientists put air into a balloon to create a closed system. They measure its circumference, warm it in hot water, and then remeasure its circumference to discover how temperature affects the...

If Hot Air Rises, Why Is it Cold in the Mountains?
Investigate the relationship between temperature and pressure. Learners change the pressure of a sample of air and monitor its temperature. They learn that as air decreases its pressure, its thermal energy converts to kinetic energy.

Climate, Weather…What’s the Difference?: Make an Electronic Temperature Sensor
What's the best way to record temperature over a long period of time? Scholars learn about collection of weather and temperature data by building thermistors in the fourth installment of the 10-part Discover Your Changing World series....
Curated OER
Rising Air
Students investigate the concept of rising air in the formation of clouds and precipitation. In this rising air lesson, students conduct an experiment with hot and cold water that shows how warm water rises due to thermal buoyancy. They...
Curated OER
Movement of Air
In this movement of air worksheet, students identify and describe the purpose for convection and how it effects Earth. Then they describe what thermals are and why they occur in hot and cold air movements. Students also explain why...
Curated OER
The Cloud Case
Learners discover how clouds form and how air pressure and air temperature affect their formation. The instructional activity is delivered in the story of Mike Breezy, Air Detective, who tries to solve The Cloud Case.
