Lesson
Dear All,
I am planning a science lesson on propulsion/expanding
gases for a kids tv series on Fireworks. Does anyone have good fun
experiment ideas we could ask the kids to take part in for the film? Also,
does anyone know the science behind the mentos and coke experiment?
Looking forward to your replies,
All the best
Agnes Becker
