If they want to make separate projects, that is fine too. Encourage talking about their ideas as they work. Write labels for different parts.
Children can take turns imitating all the adults they know as well as some children.
Discuss bossing and getting jobs done. Children can also pretend they don't want to follow the boss. Ask children what would be good props, perhaps some could come from their homes The first thing astronauts do is count down and blast off. Once in space, they go in and out of the spaceship and fix things. Children know a lot about astronauts.
