In this multi-part activity learners examine non-point water pollution.

In this activity, learners explore how water behaves differently when it comes in contact with "nano sand" and regular sand.

In this activity, learners discover that as the salinity of water increases, the density increases as well. Learners prove this by attempting to float fresh eggs in saltwater and freshwater.

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, 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 explore how the application of nano-sized "whiskers" can protect clothing from stains.

This activity offers learners and their families several ways to raise their awareness together about home water.

No glue is needed for learners of any age to become marshmallow architects or engineers.

In this activity, learners use found natural materials to create a water haven for bees and other insects.

This is an activity/demo in which learners are exposed to the difference bewteen hydrophobic surfaces (water repelling) and hydrophilic surfaces (water loving).

In this activity, learners use the design thinking process to design and build their own aqueduct, or water bridge.

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 physics activity (page 10 of the PDF), learners will explore how energy from moving water can be used.

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.

In this activity, learners build water-propelled engines from soft drink cans.

Where rainwater goes after the rain stops? And why there are rivers and lakes in some parts of the land but not in others?

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

Learners design, build, and test models of "dragon boats" made from up to three milk cartons.

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.
