🌍Earth & Space

Free interactive Earth and space science for school: why the Moon has phases, how rocks change from one type to another, and how water and carbon move around our planet. Rotate the 3D models, label the diagrams, then check yourself with a quiz or a printable worksheet.

4 simulations · free, no sign-up
🌍

Made for middle and high school

Each simulation follows the topic the way it is taught: a model to explore, the labeled diagram you need for tests, a label quiz, a short quiz and a worksheet with an answer key. Aligned with NGSS Earth and space science (for example MS-ESS1-1 moon phases and MS-ESS2-1 the rock cycle).

🌓
Moon Phases (3D)
A realistic 3D Sun–Earth–Moon model you can view from Earth. See why the Moon has phases, today’s phase and moonrise for your city, a moon calendar and eclipses, then test yourself with a label quiz and worksheet.
