Learners cover a bottle with a balloon. When they immerse the bottle in warm water, the balloon inflates. When they immerse the bottle in a bowl of ice, the balloon deflates.

In this hands-on activity, learners explore static electricity through the use of common household products. They also explore the connection between static electricity and cold weather.

In this group activity, learners use some common objects and work together to simulate the Coriolis effect. During the challenge, learners make predictions and test different scenarios.

In this activity, learners investigate wind by comparing the force of wind in different locations. Learners build wind-o-meters out of wooden sticks and strips of paper.

In this activity, learners thread colored beads onto string. Each beach represent a process of the water cycle.

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

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

In this weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.

In this activity, learners gain knowledge about how carbon moves through all four of the Earth’s major spheres (biosphere, hydrosphere, atmosphere, and lithosphere), and understand how humans influenc

Learners investigate the concept of humidity by using a dry and wet sponge as a model. They determine a model for 100% humidity, a sponge saturated with water.

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 two-part lesson, learners discover how large bodies of water can serve as a heat source or sink at different times and how proximity to water moderates climate along the coast.

In this "Sid the Science Kid" activity, learners set up a simple experiment to find out how sunscreen counteracts the effects of the sun.

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

In this water activity, learners discover ways to move water across the water table.

In this activity, learners create a biosphere in a baggie.

In this activity, learners explore sensors and focus specifically on how to measure humidity using a sensor.

In this activity, learners explore how anemometers work to record wind speeds and how the equipment has undergone engineering adaptations over time.

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.
