Learners build particulate matter collectors--devices that collect samples of visible particulates present in polluted air.

Why is ocean water sometimes the warmest when the average daily air temperature starts to drop? In this activity, learners explore the differing heat capacities of water and air using real data.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this design challenge activity, learners make a balloon hover at eye level for five seconds, and then make it move by creating air currents.

In this weather forecasting activity, learners determine the location of cold and warm fronts on weather plot maps.

In this activity, learners build small indoor paper rockets, determine their flight stability, and launch them by blowing air through a drinking straw.
