Learners explore water's property of cohesion through two investigations.

This is a simple and fun activity for learners to explore water and colors.

In this activity, learners get a closer look at the shape of a drop of water and a drop of oil. Learners first drip water onto wax paper and examine the shape of separate drops from a side view.

In this multi-part activity learners examine non-point water pollution.

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

In this activity, learners explore the different salinities of various sources of water by taste-testing.

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

In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

In this activity (on page 2 of PDF), learners mix oil and water. Then, they add soap and observe what changes! The activity demonstrates how oil and water don't mix, except when soap is added.

Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

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

Learners place multiple M&M's in a plate of water to watch what happens as the candies dissolve.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

In this activity, learners investigate and compare the rate of drying in different conditions.

In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.

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.

This is a quick activity (located on page 2 of the PDF under Nasturtium Leaves Activity) about surface tension.

In this introductory demonstration and activity, learners are introduced to the concept of density as they explore a rock and a wooden block in water.

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.

In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.
