Nitrogen and phosphorus cycles

K to 3, Grades 4 to 6, Grades 7 to 9, Grades 10 to 12

Air is made up of nitrogen (78%) and oxygen (21%) with small amounts of other gases such as argon and carbon dioxide. It probably then comes as no surprise that nitrogen is important for all organisms as it helps them to live and grow.

Soil on Mars

K to 3, Grades 4 to 6, Grades 7 to 9, Grades 10 to 12

Most people do not think twice about soil, but we could not live without it. The plants we eat, and the plants that feed the animals we eat, depend on soil. Plant roots need soil for physical support. Plants also get nutrients from soil, which they need for healthy growth and development. Future astronauts on a long-term mission to Mars will want to grow some food crops to add to their diet of packaged food.
