What does Color have to do with Cooling?
Colorado State UniversityAdd to list DetailsIn this demonstration/experiment, learners discover that different colors and materials (metals, fabrics, paints) radiate different amounts of energy and therefore, cool at different rates....
How can Clouds Help Keep the Air Warmer?
Colorado State UniversityAdd to list DetailsIn this activity, learners explore how air warms when it condenses water vapor or makes clouds. To see this in action, learners use their hands and breath to examine how evaporation cools things...
Do Cities Affect the Weather?
Colorado State UniversityAdd to list DetailsIn this activity, learners explore clouds and how they form. Learners compare the cloud formation in two bottles, one with air freshener and one without, to examine the importance of condensation...
Can Energy be Created or Destroyed?
Colorado State UniversityAdd to list DetailsIn this activity, learners explore conservation of energy by experimenting with a solar cell light device. Learners will set the solar cell in the sun for varying times to charge the battery and...
What is a “Convection Cell”?
Colorado State UniversityAdd to list DetailsIn this demonstration, learners can observe a number of small convection cells generated from a mixture of aluminum powder and silicon oil on a hot plate. This demonstration helps learners...
Does Air Weigh Anything?
Colorado State UniversityAdd to list DetailsThe demonstration/experiment provides quick proof that air has mass. Learners measure the mass of a 2-liter bottle attached with special "Fizzkeeper" cap before and after extra air...
How Can Gravity Make Something Go Up?
Colorado State UniversityAdd to list DetailsIn this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises. Learners can use a hair dryer to...
If Hot Air Rises, Why is it Cold in the Mountains?
Colorado State UniversityAdd to list DetailsThis demonstration/activity helps learners understand why higher elevations are not always warm simply because "hot air rises." Learners use a tire pump to increase the pressure and...
How does the Atmosphere keep the Earth Warmer?
Colorado State UniversityAdd to list DetailsIn this activity, learners simulate the energy transfer between the earth and space by using the light from a desk lamp desk lamp with an incandescent bulb and a stack of glass plates. The stack of...
