Extra Parts Recommendations for 3 children

The Astronomy Adventure already works well for two children working together. With the understanding that it's not necessary for each child to have all their own equipment, here are our minimum recommendations for adding a third child, so all three will have a good experience without waiting around. These recommendations assume that the children can share a little, but won't want to wait too long.

For 3 children working at the same time, add:
1 sheet of planet stickers
1 artificial gravity set
1 wooden ruler
2 jumbo paper clips

Below is an extra parts form filled in with these recommendations. Feel Free to check, uncheck or change quantity on anything on the list.
