In this activity, learners explore how to protect their skin while applying pesticides to plants.

In this activity, learners discuss the different salinities of oceans, rivers and estuaries.

This activity uses Jell-O(R) to introduce learners to microfluidics, the flow of fluids through microscopic channels.

In this activity, learners use aluminum trays and wooden blocks to form stream tables to investigate river formations in two different landscape scenarios.

In this activity related to climate change, learners create and explore topographical maps as a means of studying sea level rise.

This online interactive has three activities in the NanoLab (press the upper right button): Build, Zoom, and Transform.

In this activity on page 9 of the PDF, learners test how flavoring extracts move through the walls of a balloon.

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 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.

In this activity, learners conduct an experiment by heating an aluminum can filled with water to investigate air pressure.

In this activity (on pages 29-35), learners examine water pollution and filtration.

Did you know that the water we use today is the same water found on Earth millions of years ago? The Earth constantly uses and recycles water in a process called the water cycle.

In this activity on page 8 of the PDF, learners make a slimy substance very similar to mucus, and sprinkle it with glitter to imitate the way that allergens are trapped.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

This kinesthetic science demonstration introduces learners to four states of matter: solid, liquid, gas, and plasma.

In this activity, learners act as water molecules and travel through parts of the water cycle to discover that it is more complex than just water moving from the ground to the atmosphere.

In this experiment, learners use a blow dryer and water bottle to observe and record changes in air pressure caused by changes in temperature.

Water treatment on a large scale enables the supply of clean drinking water to communities.

In this physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

Learners explore the variables that affect the properties of ice and the places where different types of ice are found.
