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

In this water activity, learners discover ways to move water across the water table.

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 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 physics activity, learners will explore buoyancy.

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.

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

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 observe the hydrologic cycle in action as water evaporates and condenses to form rain right before their eyes.

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.

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