In this activity, learners investigate how plants use water. By making the flowers change color, learners see how water moves up the stem to the leaves and the flowers.

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

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

In this activity, learners use sieves with different-sized holes to sort balls by size.

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 will explore the density of an object in water. Learners will compare what happens to fruits and vegetables in regular and salt water.

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 capture and observe planaria, which are worms that eat tiny pond critters.

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

If you got a big graduated or clear cylinder, water, a pipe, and a tuning fork, you've got a sound learning opportunity! Learn about resonance with this Exploratorium Science Snack.

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

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

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

In this activity/demonstration, learners observe what happens when two ping pong balls are suspended in the air by a hair dryer. Use this activity to demonstrate how rain drops grow by coalescence.

In this nanoscience activity, learners discover that it's easy to pour water out of a regular-sized cup, but not out of a miniature cup.

In this activity, learners model atmospheric convection currents using food coloring, water, and clear cups. Activity includes step-by-step instructions, STEM connections, and more.

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, learners will explore how water affects marker on filter paper. Learners will use science process skills such as making observations and predictions as they explore color.

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