This is a simple and fun activity for learners to explore water and colors.

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

In this activity, learners will explore basic information about thermodynamics by experimenting with ice. Learners will compare ice melting rates on metal pans or plastic cutting boards.

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

In this activity, learners will observe laminar and turbulent flow of water using only a plastic bottle, liquid hand soap, food coloring and water.

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, learners play with surprising sand that doesn’t get wet! Learners explore how water behaves differently when it comes in contact with "magic sand" and regular sand.

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

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 found natural materials to create a water haven for bees and other insects.

Test the buoyancy of an aluminum foil boat and an aluminum foil ball. Why does the same material in different shapes sink or float?

In this activity, learners consider the water features they might enjoy at a community park--a pond, brook, water playground (or "sprayground"), or pool--and what happens to the water over time.

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, learners use objects they find on a nature and water to make creative frozen sculptures.

In this activity, learners create secret messages using a candle. Learners discover that watercolor paint is attracted to some materials, like paper fibers, but not others, like oil.

This activity gives caregivers and their children an opportunity to practice scientific ways of thinking that are developmentally appropriate for early learners.

In this activity, learners explore atoms as the smallest building blocks of matter. With adult help, learners start by dividing play dough in half, over and over again.

In this activity learners will explore how water moves on waxed paper. Learners will use science process skills such as using tools and making observations as they explore surface tension.

In this physics activity, learners will explore buoyancy.
