In this activity (on page 2 of the PDF), learners explore surface tension by adding pennies to cups which are "full" of plain water or soapy water.

Learners observe a bottle containing water and oil. They are invited to pick up the bottle and mix the contents together.

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 activity (on page 2 of the PDF), the learner places a golf ball between salt water and colored fresh water. The golf ball is not as dense as the saltwater.

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

Learners create hard water by mixing Epsom salt and water. Then they compare what happens when soap solution is mixed with hard water and regular water.

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.

Learners add different liquids (water, salt water, alcohol, and detergent solution) to water and observe the different ways the different liquids combine with water.

An estuary is a body of water that is created when freshwater from rivers and streams flows into the saltwater of an ocean.

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

Learners investigate the properties of the liquids in two bottles. One contains layers of oil and water, and one contains oil, water, and soap.

Learners use filter paper and water to analyze six different markers. They mark the paper with ink, and dip the paper in water. The water travels up the paper and dissolved ink travels with it.

This is an activity (located on page 3 of PDF under Nasturtium Leaves Activity) about surface tension.

Does yeast breathe? Find out by watching how plastic bags filled with yeast, warm water and different amounts of sugar change over time.

Learners observe and compare the sizes of three toy “growing” crocodiles made from water-absorbent polymers. One is it its original state, dry, hard, and about 10cm long.

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

This activity provides instructions for using cornstarch and water to make an ooze which has the properties of both a solid and liquid.

Eggs are placed in vinegar for one or two days to dissolve the shells. Then, learners place the eggs in water or corn syrup and observe them over a period of days.

In this chemistry activity (on page 2 of the PDF), learners corrode a penny in a cup with vinegar, salt water, and a source of iron (nails, paper clips, or twist ties).

Learners mix liquid water with solid cornstarch. They investigate the slime produced, which has properties of both a solid and a liquid.
