In this activity, learners explore the different salinities of various sources of water by taste-testing.

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 if carbon dioxide has an effect on temperature.

In this activity, learners observe how salinity affects the freezing point of water by making and enjoying ice cream.

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 observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this activity, learners explore how light and dark colored objects absorb the Sun's radiations at different rates.

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 activity, learners will measure the length of their shadow from the Sun and compare it three to four months later.

In this activity, learners estimate how much water they think can be found in various locations on the Earth in all its states (solid, liquid, and gas) to discover the different water ratios in the Ea
