See what teachers & students have to say:

"My students finally understood why the seasons happen instead of just memorizing the dates. Watching the axis stay tilted the same way while the Earth model moved around the sun made it click for kids who'd never gotten it before."

— Ms. Reyes, 4th Grade Teacher

"I didn't know Earth's tilt never changes! I always thought summer meant we were closer to the sun. Now I can actually explain equinoxes to my little sister."

— Maya L., 4th Grade Student
