Introduction to Nutrients in Water and Demonstration of Simple Test Procedures

What does the ground around your home have to do with water pollution? Young ecologists learn about their local watershed and create their own cause-and-effect models of the hydrosphere.

Trying to plan a physical science unit on forces and motion? Make your work a little easier with this comprehensive collection of simple machines resources. Offering a wide variety worksheets, activities, and projects, these materials...

Why does soda fizz when opened? Learners discuss the appearance of bubbles in soda bottles when opened. In groups, they design and complete an experiment comparing the amount of carbon dioxide dissolving in cold versus hot liquids.  

From their sweat to the water vapor in their breath, astronauts recycle every possible drop of water while in space. After watching a short video describing the different ways materials are recycled and reused in space shuttles, young...

Ecology candidates culture pond water organisms over a few days time, then they experiment to find out how increasing nutrients affects the population. As part of a unit on water, this exploration gives your class an understanding of how...

How does food coloring work? Classes watch a demonstration showing liquids dissolving in liquids. In groups, they then explore the ability of other liquids to dissolve in water (alcohol, mineral oil, and corn syrup) by setting up and...

A water strider is a bug that taps into the attraction between the positive and negative ends of water, allowing the bug to walk on water. Learners view short videos showing polar characteristics of water. Pairs then discuss what polar...

Did you know that if you wait long enough, the M on the outside of an M and M will float to the surface when submerged in water? Learners observe the sugar coating of an M and M while it is dissolving in water. They explain how this...

Having fresh, clean drinking water is a privilege many people take for granted. Help raise awareness about the scarcity of water and the importance of conservation by discussing different ways water is used in everyday life. Brainstorm...

Make your work as a teacher a little easier with a physical science project on simple machines. After introducing young scientists to these devices and identifying their different uses around the school, this project engages children in...
