Simulations

Fly around a real 3D Moon, then stand on Earth and look up. The phase is which part of the lit half faces you.

Watch sunlight come in and infrared heat try to leave. Change the carbon dioxide and hold the planet at a target temperature.

Venus is twice as far from the Sun as Mercury. Which one is hotter? Give each planet a blanket of gas and find out.

Fly Earth around the Sun, then stand anywhere on it. Seasons come from the tilt, not from how close we are to the Sun.

Be a carbon atom. Fly an island as carbon dioxide, slip into a leaf and become sugar, then choose: burned for energy, grown into wood, fallen and rotted, or eaten by a cow.
