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 a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

In this weather activity (page 4 of the PDF), learners will explore the water cycle through an interactive game.

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

In this activity, learners observe color mixing and absorbency using colored tissue paper and spray bottles.

In this activity (on pages 29-35), learners examine water pollution and filtration.

This experiment is designed to illustrate how fluids, including water, have the ability to flow.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.

In this outdoor activity, learners compare the moisture released from different kinds of leaves and from different parts of the same leaf, by observing the color change of cobalt chloride paper.

In this activity, learners explore properties of water and watch evaporation happen by "painting" with water in the sun.

In this activity, learners experiment with surface tension using everyday household items such as strawberry baskets, paperclips, liquid dish soap, and pepper.

In this outdoor water activity, learners explore evaporation by painting with water and tracing puddles. Learners will discover that wet things become dry as the water evaporates.

This Exploratorium activity can be used in many contexts because geysers are great opportunities for learning about heat and temperature changes as well as geological/space science phenomena.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water.

This activity about density provides instructions for making a miniature "lava lite" with just salt, oil, water, and food coloring.

In this water activity, learners explore how water drops behave on different surfaces.

In this activity, learners use a laser pointer to project a microscopic image of a liquid sample suspended from the tip of a syringe.

In this activity, learners observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.
