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.

Exploring the Ocean with Robots
Source Institutions
In this activity, learners are introduced to robotic submarines called gliders. Learners make “gliders” from plastic syringes and compare these to Cartesian bottles and plastic bubbles.

The Squeeze Box
Source Institutions
In this geology activity learners build a "squeeze box," which allows them to compress layers of sediment. This is a great way to investigate folding and faulting in the Earth.
