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

Learners see that a carrot slice sinks in fresh water and floats in saltwater.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

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.

Learners will see that changing the shape of an object, like a clay ball, that is more dense than water, can affect whether the object will sink or float.

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

In this activity, learners explore and compare the buoyant properties of materials found in nature and in human-made materials.

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

Learners discover that soap can be used to power a boat. Learners make a simple, flat boat model, put it in water, and then add a drop of detergent at the back of the boat.

In this botany activity, learners will create an experiment about seed germination. This activity gives students an opportunity to explore how seeds germinate and react to surrounding conditions.

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 is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

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 activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

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.

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

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

This activity has learners observe water and compare it to other liquids.

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