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

In this activity, learners create their own weather forecast map.

In this activity, learners create their own icons for a forecast-at-a-glance poster for their classroom/learning space.

In this activity, learners will estimate the sizes of balls to learn how to estimate the size of hail. Learners will compare their estimates to the estimates of their peers and the real measurements.

In this weather activity/demonstration, learners watch as a ping pong ball is suspended in a stream of air supplied by a hair dryer.

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

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this activity, learners use simple items to construct a device for indicating air pressure changes.

In this weather forecasting activity, learners use common materials to construct a rain gauge and measure daily, monthly, and yearly rainfall.

In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

In this activity, learners create a CloudSpotter wheel and record the different types of clouds they observe twice daily over several days.

In this activity on page 27, learners perform an experiment to learn about how different types of marine debris degrade and how weather and sunlight affect the rate of degradation.

In this activity, learners will listen to as many radio stations as possible to discover that AM radio signals can travel many hundreds of miles at night.

Learners complete a series of hands-on and investigative activities to explore cumulus clouds.

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

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

In this activity, learners discover how the extent of various wind speeds changes in each of the four quadrants around a hurricane.

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 observe how salinity affects the freezing point of water by making and enjoying ice cream.
