Explore
Pick a place. Then do something with it.
Start with a world you know. Ages 5 to 7 can use the short notes. Older explorers can open the longer ones.
- Solar systemThe Sun and the planets. Tap a world.
- MoonsFamous moons, as cards.
- RocketsThrust, fuel, and real vehicle families.
- AstronautsWho has flown, and who is flying.
- A launchThe steps from the wait to liftoff.
- Stars tonightThe Big Dipper, meteors, and the Moon.
- Space LabDo an experiment, then read the science.
- MysteriesClues first. Then the name.
Farther out
Short notes only. They are not a full course, and they are not copied from an agency page.
Stars
The Sun is a star. Other stars are suns so far away they look like points. A constellation is a pattern people drew, not a family of stars that must be close together.
Galaxies
A galaxy is a huge gathering of stars, gas, and dust. We live in the Milky Way. Other galaxies are much farther than any planet.
Black holes
A black hole is a place where gravity is so strong that light cannot get out. We have not visited one. Pictures and models are not the same as going there.
Asteroids and comets
Asteroids are rocky leftovers. A comet is an icy lump that can grow a tail when it nears the Sun. The tail points generally away from the Sun.
Worlds around other stars
Planets orbit other stars too. We have not found life on them. “Scientists think” is not the same as “we know.”
