This task gives students a chance to explore the effects of the Earth's tilt and rotation using a simple geometric model of Earth-Sun interaction that shows why the seasons occur. Aligns with G-MG.A.1.

Students perform many inquiry activities related to Earth's orbit. Included are recording daily temperatures, observing the sun's path over several weeks, tracking sunrise and sunset times, and angle of sunlight. Diagrams make lessons...

This simulation allows the user to see the sun's arc in the sky anywhere in the world at any time. By changing the season settings the user can see how seasons affect the height of the sun's arc.
