In this easy chemistry activity, learners submerge pennies in different liquids (water, lemon juice, vinegar, liquid hand soap, salt water, and baking soda mixed with water) to observe which best clea

How Much Water is in that Cloud?
Source Institutions
In this activity, learners working in pairs saturate a cotton ball using water drops from an eyedropper to demonstrate the high water capacity of clouds.

Wiggly Water
Source Institutions
This is a simple and fun activity for learners to explore water and colors.

Weather Stations: Phase Change
Source Institutions
In this activity, learners observe the water cycle in action! Water vapor in a tumbler condenses on chilled aluminum foil — producing the liquid form of water familiar to us as rain and dew.

Physics Over the Sink: Water Glass Magic
Source Institutions
In this simple demonstration, learners investigate the properties of air pressure. Learners place an index card on top of a glass full of water, then invert the glass.

Twist and Spout
Source Institutions
In this activity, learners make their own "tornado" using two soda bottles and water.

It's a Gas!
Source Institutions
In this simple activity, learners see the production of a gas, which visibly fills up a balloon placed over the neck of a bottle.

Diet Light
Source Institutions
In this quick activity, learners observe how the added sugar in a can of soda affects its density and thus, its ability to float in water.

Release the Grease!
Source Institutions
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.

Find Out How Plants Use Water
Source Institutions
In this activity, learners investigate how plants use water. By making the flowers change color, learners see how water moves up the stem to the leaves and the flowers.

Color-Changing Carnations
Source Institutions
Learners place cut flowers in colored water and observe how the flowers change. The flowers absorb the water through the stem and leaves.

The Scoop on Habitat
Source Institutions
Some aquatic organisms live in open water, while some live in soil at the bottom of a body of water.

Crystal Creations: Grow Spikes of Crystals in the Sun
Source Institutions
This activity shows you how to make amazing crystal spikes using Epsom salt and the sun.
