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

In this activity, learners "draw" with frozen tempera paint. The ice cubes are prepared the day before by placing watered down tempera paint and popsicle sticks in ice cube trays.

In this activity (located on page 10 of the PDF), learners explore the properties of spraying and dripping water, while making art.

By building a simple watershed with paper and markers and then using a spray bottle to simulate precipitation, learners will understand how pollution accumulates in our water sources, especially from

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

In some parts of the world, lakes freeze during winter. In this activity learners will explore water’s unique properties of freezing and melting, and how these relate to density and temperature.

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

In this activity, learners will make fish cutouts that propel through the water with the help of surface tension.

This is an activity about Newton's First Law of Motion - a body in motion tends to stay in motion, or a body at rest tends to stay at rest unless acted upon by an outside force.

In this quick activity (located on page 2 of the PDF under GPS Wetlands Activity), learners will model how wetlands act as natural filters for the environment.

Learners model the ocean currents that carry hot water from the tropics to northern latitudes.

In this weather-related activity, learners make a portable cloud in a bottle.

In this quick activity about pollutants and groundwater (page 2 of PDF under Water Clean-up Activity), learners build a model well with a toilet paper tube.

In this activity, learners will use string and salt to lift an ice cube out of a glass of water. Salt depresses the freezing point of water, allowing it to melt around the string and refreeze.

In this activity about light, learners explore how water can refract light and change the way they see things.

Electrolysis is the breakdown of water into hydrogen and oxygen. This Exploratorium activity allows learners to visualize the process with an acid-based indicator.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

Learners are challenged to discover the relative densities of colored liquids to create a rainbow pattern in a test tube.

In this quick activity (located on page 2 of the PDF under GPS: Balloon Fiesta Activity), learners will see the effects of convection and understand what makes hot air balloons rise.
