In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.

In this experiment, learners examine how pressure affects water flow. In small groups, learners work with water and a soda bottle, and then relate their findings to pressure in the deep ocean.

In this simple activity (on page 7 of the PDF), learners use water and liquid dish detergent to see which one removes lipstick better from an index card.

Learners act as engineers and design mini submarines that move in the water like real submarines.

In this activity, learners explore why humans sweat. Learners compare the effects of heat on a balloon filled with air and a balloon filled water.

In this activity, learners observe the effect of transpiration as water is moved from the ground to the atmosphere.

In this activity, learners discover that they can create a lens from a water drop. Learners test their lens by looking at words or pictures.

In this activity, learners investigate convection by using food coloring and water of different temperatures.

In this simulation activity, learners observe what can happen when ocean waves churn up water and oil from an oil spill.

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

In this activity, learners explore how salt water freezes in comparison to fresh water.

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

In this math lesson (page 2 of the PDF), learners use bottles of various shapes to explore the abstract concept of rate of change.

In this simple activity, learners explore ocean waves. To find out if water moves forward toward the shore, learners create waves in a simulated ocean (small aquarium tank of water).

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 fun gardening activity, learners discover their soil type. There are three basic soil types: sand, silt, and clay.

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

How many colors make black? Gather as many water soluble black markers as you can find.

In this activity, learners make a model of the hot water of a deep sea vent in the cold water of the ocean to learn about one of the ocean's most amazing and bizarre underwater habitats.
