Learners build a simple aneroid barometer to learn about changes in barometric pressure and weather forecasting. They observe their barometer and record data over a period of days.

Learners use M&Ms® (or any other multi-color, equally-sized small candy or pieces) to create a pie graph that expresses the composition of air.

In this chemistry activity, learners explore chemical reactions and their effects, including the kind of reaction in the human body that makes people burp!

Get all wrapped up in a lesson about skin!

In this activity, learners use plastic water bottles, wood, and water to build an inexpensive and portable tool to demonstrate one atmosphere of pressure at sea level.

In this activity, learners build a slide whistle using PVC pipe, bamboo skewer, and piece of foam. Construction of the instrument is relatively simple.

In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod

Learners develop an understanding of air pressure in two different activities.
