Astronomy Classroom

The Astronomy Classroom is the second-to-last classroom that costs coins, that you can unlock. It costs 18,000 coins to build. Once you have built it, you can spend 1 apple to start the construction. After that, you wait for 2 days for it to hire a teacher. Or you can skip it by paying brownie points. Once it completed, players can spend one apple to teach. The classroom takes 6 hours before harvesting, but gives out 123 coins, 1, 2, or 3 XP, and possibly 1 Science Compitition point or an apple.
