What a course could cover
The exact outline depends on the level and length you pick. A space course might include:
- Scale and distance
- Orbits and gravity
- How stars change
- Spaceflight and exploration
Example cards
Orbit is a continuous fall
A spacecraft falls towards Earth while moving sideways fast enough that the curved surface keeps dropping away beneath it.
Two ideas side by side
Some cards compare two things directly, when that’s the clearest way to show the difference.
Why does an orbiting spacecraft not fall straight down?
Answer in the app and it tells you why you were right or wrong.
This is just an example
In the app you can go broader, get much more specific, or pick a different subject entirely.
