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

Learners compare the weight of equal volumes of wax, water, and clay. Learners discover that since the wax weighs less than an equal volume of water, it is less dense than water and will float.

In this activity (located on page 6 of the PDF), learners explore the ways people access water in their homes.

This warm weather activity introduces learners to the impact trees have on blocking the sun's heat and reducing temperature on the Earth's surface.

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

Build a hydrometer (measures the density of a liquid) using a pipet or eyedropper.

In this activity, learners explore how engineering has developed various means to remove impurities from water.

In this activity about water solubility and density, learners use critical thinking skills to determine why water can dissolve some things and not others.

In this three-part activity, learners play a game and conduct two simple experiments to explore water and surface tension. Learners will have fun discovering how water "sticks" together.

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

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

This is an activity about turbidity, or the amount of sediment suspended in water.

Glare from the sun and ripples from the wind can make it hard to see what's below the surface of a body of water.

In this activity, learners use objects they find on a nature and water to make creative frozen sculptures.
