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

In this activity, learners get hands-on experience with ratios and scaling while making their own jewelry out of recycled plastic containers.

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

In this game, learners walk through an imaginary Carbon Cycle and explore the ways in which carbon is stored in reservoirs and the processes that transport the carbon atom from one location to another

In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

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

In this activity, learners will determine if the frequency and intensity of hurricanes are changing using real data from the National Hurricane Center.

In this activity related to climate change and data analysis, learners examine temperature and precipitation data to determine if climate variations are due to El Niño.

In this lesson plan, learners examine some of the of greenhouse gas emissions sources in their community.

In this experiment, pairs of learners explore how cold water affects circulation. The mammalian diving reflex (MDR) slows circulation when the body is exposed to cold water.

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 activity about states of matter, learners get to witness firsthand the awesome power of air pressure. They watch as an ordinary soda can is crushed by invisible forces.

In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.

In this activity (on page 7), learners explore the meaning of a "carbon sink." Using simple props, learners and/or an educator demonstrate how plants act as carbon sinks and how greenhouse gases cause

In this activity, learners graph 48 hourly air temperatures from a local weather observation site and observe the diurnal temperature variations.

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.

In this data collection and analysis activity, learners evaluate fish physiology and ecology using vision research data from Dr.

In this activity (on page 2 of the PDF), learners (with adult help and supervision) investigate how heat affects polystyrene plastic.

In this activity, learners simulate the behavior of the atmosphere.

In this environmental science and data analysis activity, learners work in groups to track a Dead Zone (decreased dissolved oxygen content of a body of water) using water quality data from the Nutrien
