In this activity, explore chromatography and the various colors that make up the ink in markers. Use this activity to investigate cohesion and adhesion.

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 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, learners use tinfoil to build and test their own boats - which designs will float, and which will sink?

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

In this hands-on activity, learners use the steps of the design process to create a hook to rescue a "space capsule" from the water.

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.

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, learners calculate their water usage (in cups and galloons) during an average shower. Learners also chart and analyze water usage during showers in their households.

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

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

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 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.
