"What's in the Water" lets participants use tools to solve the mystery- what chemicals and compounds are in a sample of water?

In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.

In this simple activity (on page 7 of the PDF), learners use water and liquid dish detergent to see which one removes lipstick better from an index card.

In this activity, learners use sieves with different-sized holes to sort balls by size.

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 will explore the dynamics of air pressure by using a candle, a cup, and a dish of water.

In this activity, learners mix up a bubbly brew and examine density. Learners explore how they can make different materials fall and rise in water using oil, water, and salt.

In this activity, learners discover how a super-absorbing material can be used to move a straw.

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

In this activity, learners mix water, cooking oil, and liquid food coloring to create beautiful colored designs in a cup. Use this activity to explore liquid density and solubility.

In this activity, learners make a foam packing peanut "flink"--neither float away nor sink--in water. Learners experiment with materials to make a Flinker that "flinks" for 10 seconds.

This activity models some of the ways natural processes, such as erosion and sediment pollution, affect Earth’s landscape.
