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 discover how to determine the distance to a lightning strike or nearby thunderstorm.

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

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 engineering activity, learners build a device (an anemometer) to measure how fast the wind is blowing.

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 use simple items to construct a device for indicating air pressure changes.

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

This lesson plan enables learners to explore the differences between weather and climate.

In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

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 test how cornstarch and glitter in water move when disturbed. Learners compare their observations with videos of Jupiter's and Earth's storm movements.

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 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 activity, learners conduct three experiments to examine temperature, the different stages of the water cycle, and how convection creates wind.

In this interactive and informative group activity, learners use packages of M&M's to illustrate the difference between weather and climate.

In this activity, learners will engineer their own weather vane. This activity includes step-by-step instructions with pictures and a "What's Happening?" section explaining how the activity worked.

In this activity, learners will explore the water cycle by creating a small atmosphere.
