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

The major goal of this math lesson is to have learners collect data from a variety of experiments, determine what models best fits their data, and explain why their models are best.

In this activity, learners use cheap, thin plastic garbage bags to quickly build a solar hot air balloon. In doing so, learners will explore why hot air rises.

In this activity, learners explore how various energy sources can be used to cause a turbine to rotate.

In this activity, learners investigate how inkjet printers produce tiny, precise drops of ink.

In this quick and easy activity and/or demonstration, learners use two empty 2-liter bottles and hot tap water to illustrate the effect of heat on pressure.

In this oceanography and data collection activity, learners cast real time sea state conditions using buoys from NOAA's National Data Buoy Center.

In this activity, learners build a hot air balloon using just a few sheets of tissue paper and a hair dryer.

In this activity, learners discover the relationship between temperature and pressure in the lower atmospheres of Jupiter and Earth.

In this activity learners compare the bounciness of warm and cold racquetballs to see if temperature makes a difference in how well they bounce.

In this activity, learners determine whether thermal energy can be used for work.

In this quick activity, learners use a toaster to investigate the source for the Earth's wind. Learners hold a pinwheel above a toaster to discover that rising heat causes wind.

In this physics activity, learners construct a small-scale version of a classic carnival game.

In this activity, learners make a model of a power plant that uses steam. Learners use simple materials like foil, a tin can, and a pot of water to model a geothermal power plant.

In this activity, learners create a model of a hot air balloon using tissue paper and a hairdryer. Educators can use this activity to introduce learners to density and its role in why things float.

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

In this online Flash game, learners take to the skies in a hot air balloon and are challenged to beat other balloonists' times to the finish line without crashing.

Cool off in the heat with this project! Learners use simple materials to build a fan that runs on a motor.

In this activity, learners explore the history of making objects from glass and artistry of Dale Chihuly.

In this two-part activity, learners work in pairs to examine the four basic stages of a turbine engine.
