Our World A Complex Eco-system

Can we model how large the solar system really is? Attempt an astronomical feat with a hands-on-activity that uses a roll of toilet paper. Young scientists measure the distances of the planets from the sun to create a scale model of the...

How in the world can something as big as the solar system possibly fit in your pocket? Complete this simple modeling activity and find out, as young scientists gain an appreciation for the incredible scale of outer space.

Math and science come together in this cross-curricular astronomy lesson plan on planetary motion. Starting off with a hands-on activity that engages the class in exploring the geometry of circles and ellipses, this lesson plan then...

Eco-schools is a project of the National Wildlife Federation and empowers schools to manage their schools with a green focus. Scholars work to define environment and sustainability and springboard this into learning the eight pathways...

Take your class on a journey through our solar system. Learners explore each planet, from Mercury to Pluto, and discuss various features that differentiate one from another. They complete activities related to the topics and discuss the...
