Do Cities Affect the Weather?
Source Institutions
In this activity, learners explore clouds and how they form.
Finding the Right Crater
Source Institutions
This quick demonstration (on page 11 of PDF) allows learners to understand why scientists think water ice could remain frozen in always-dark craters at the poles of the Moon.

Aerogel-lo
Source Institutions
This demonstration (on pages 9-11) uses gelatin and lead pellets to model how aerogel, a technology used by NASA spacecrafts, is used to capture comet particles.

Weather Stations: Temperature and Pressure
Source Institutions
In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.
What's So Special about Water: Absorption
Source Institutions
In this activity about water's cohesive and adhesive properties and why water molecules are attracted to each other, learners test if objects repel or absorb water.
Pepper Scatter
Source Institutions
In this activity, learners explore the forces at work in water. Learners experiment to find out what happens to pepper in water when they touch it with bar soap and liquid detergent.
