Question by Sarah: Rockets (bottle) for younger kids science experiment?
OKay so I’m volunteering at a camp and the theme is the show FETCH so apparently it’s about science experiments and stuff. So we have to put on a science fair I have a group of about 4 girls and they want to do something with rockets? but I don’t know how any help? BY& the way there in 3rd and 4th grade.

I think that water rockets would be a much more interesting thing to demonstrate than cheap fireworks. Fireworks demonstrate magic, not science. You light the fuse, they go “fffffft pop!” What have you learned? Nothing.
They can build their own water rockets. (or, if you don’t have time for that, you can buy ready-made ones in a toy store) They will get much more of a sense of what “reaction mass” means with a water rocket.
Google “water rocket” to learn more.
