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

Many people get water from a source deep underground, called groundwater.

Water on Earth is in lakes, the ocean, rivers, underground, and frozen glaciers.

Learners work in teams to design and build solar water heating devices that mimic those used in residences to capture energy in the form of solar radiation and convert it to thermal energy.

In this activity, learners explore the concept of density-driven currents (thermohaline circulation) and how these currents are affected by climate change.

In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.

In this three-part activity, learners explore how waves are formed and why some waves are bigger than others. First, learners observe waves of water in a pan generated by an electric fan.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

In this activity (page 13 of the PDF), learners discover how weathering and erosion change the Earth’s surface.

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

In this activity, learners construct models of plants that are adapted to living under specific environmental conditions.
