In this activity, students create a scale model depicting the vertical distance from Earth’s surface to various features and objects, including Earth’s atmospheric layers, the Van Allen Radiation Belts, and geocentric satellites. Students also... (View More) compare the vertical distances to these features and objects with distances from their classroom to other common points on the ground.

This is a lesson about the electromagnetic spectrum. Learners begin by arranging a set of picture cards; in the discussion afterwards, this activity is related to the electromagnetic spectrum as an arrangement of energy waves. Next, using a... (View More) clothesline to model a logarithmic scale, they add in the electromagnetic spectrum. Finally, learners conduct several simple tests to detect other types of radiation. This activity requires access to a sunny outdoor location and the use of ultraviolet light-sensitive beads. (View Less)
