What Makes Water Special?
Get close up and personal with a drop of water to discover how the polarity of its molecules affect its behavior. Elementary hydrologists split and combine water droplets, and also compare them to drops of oil. Much neater than placing a...

What is the Water Cycle? Activity A
Hydrologists create a concept map about how water is used and a sentence strip defining water and describing its unique properties. Small groups work together to fill a small milk carton and compute the mass of water inside. The next...

Looking at Water - Solid, Liquid, or Gas
Here's a tip: only one substance is commonly found as a solid, liquid, and gas. Learners use that knowledge as they investigate the properties of water in each state. They interact with water in each of its three phases and record what...

Comparing the Density of an Object to the Density of Water
Investigators construct a makeshift balance and compare equal volumes of wax and water. They do the same for clay and water. Then they discover whether the wax and clay will float or sink in water. Ultimately this is a comparison of...
