In this activity, learners will simulate the processes of the water cycle at home in a plastic sandwich bag.

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

In this water pollution activity, learners create pond water cultures and investigate the effects of adding chemicals or natural nutrients.

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

This is an activity (located on page 3 of the PDF under Water Clean-up Activity) about the use of reduction agents to decontaminate ground water.

In this outdoor, sunny day activity, learners experiment with paper leaf models to discover how some desert plants conserve water.

In this lab, learners experience how dolphins and other echolocating animals use their senses to locate and identify objects without using their sense of sight.

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

In this activity, learners investigate soil erosion. Learners set up a simulation to observe how water can change the land and move nutrients from one place to another.

In this environmental science activity (page 3 of the PDF), leaners will identify and explain the causes of erosion.

In this hands-on activity, learners will construct a scuba diver that can float in order to explore how sea creatures stay neutrally buoyant in the ocean and to see what kinds of forces might be influ

In this activity, learners perform an experiment that models a chromatography-like process called electrophoresis, a process used to analyze DNA.

Learners create three solutions with different levels of salinity. They compare the density of these solutions by coloring them and layering them in a clear plastic cup and in a soda bottle.

In this activity about the circulatory system and space travel (on page 38 of the PDF), learners use water balloons to simulate the effects of gravity and microgravity on fluid distribution in the bod

In this outdoor activity, learners visit the intertidal zone of a rocky coastal site well populated with marine organisms.

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

This hands-on experiment will provide learners with an understanding of the issues that surround environmental cleanup.

In this edible experiment, learners pour "Magic Shell" chocolate into a glass of cold water. They'll observe as pillow shaped structures form, which resemble lavas on the sea floor.

In this three-part activity, learners use food to determine the effects of wind, sandblasting and water on regolith (dust) formation and deposition on Earth.

In this activity, learners use a flashlight, a glass of water, and some milk to examine why the sky is blue and sunsets are red.
