In this outdoor water activity, learners explore evaporation by painting with water and tracing puddles. Learners will discover that wet things become dry as the water evaporates.

In this water activity, learners explore how water drops behave on different surfaces.

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

In this indoor or outdoor water activity, learners pour water from small cups to large cups and containers. In doing so, they discover water takes the shape of its container.

In this activity, challenge learners to float a paper clip in a cup of water. Learners discover that a paper clip will sink in a cup of water, except when it is placed on a piece of paper towel.

In this outdoor water activity, learners explore how to change the direction of water flow. Learners make puddles in dirt or use existing puddles and sticks to make water flow.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this water activity, learners test which objects float and which sink. Learners discover that objects behave differently in water.

In this design challenge activity, learners build a boat that can hold 25 pennies (or 15 one inch metal washers) for at least ten seconds before sinking.

In this activity, challenge learners to predict and investigate how many water drops they can fit on one penny.

In this water activity, learners build boats that float and sink. First, learners listen to the book, "Who Sank the Boat" and practice making predictions throughout the story.

This series of chemistry stations is designed to accompany the PBS documentary about African-American chemist "Percy Julian: Forgotten Genius." Each of the six stations features either a chemical or p

In this activity, learners mix milk, vinegar, baking soda, and water to create sticky glue. Use this activity to explain how engineers develop and evaluate new materials and products.

In this hands-on science experiment, students combine their understanding of the different states of matter and the characteristics of various chemical reactions.
