Traveling Nitrogen

Nitrogen is an element that is found both in living things and the nonliving parts of the Earth system. In this classroom activity, students play the role of nitrogen atoms traveling through the nitrogen cycle to gain understanding of the varied pathways through the cycle and how nitrogen is relevant to living things.

Using Energy Resources Wisely

People depend on their energy resources, so they need to know how to use them wisely. How do you think people can use the energy they rely on to heat their homes more efficiently?

Wash This Way!

People interact with Earth’s water (hydrosphere) in a variety of ways. We depend upon water for survival, but we also need it to keep clean and help avoid spreading disease. On our ever-changing Earth, the supply of fresh water can be limited for some humans. We need good techniques to make the best use of the fresh water we do have. For example, when you wash your hands, how do you do it? With soap and water? With water alone? Do you scrub your hands or simply rinse them under the faucet? Does it even matter? Yes, it does!
