In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

In this kinesthetic activity that demonstrates pressure, learners act as air molecules in a "container" as defined by a rope.

In this activity, learners discover how to determine the distance to a lightning strike or nearby thunderstorm.

Through doing these hands-on activities, learners explore the environmental consequences associated with fossil fuel usage.

This activity explores the basic workings of a siphon, which is the core technology that makes toilets work.

This experiment allows learners to experience a small scale "epidemic," demonstrating the ease with which disease organisms are spread, and enables learners to determine the originator of the "epidemi
