How long should my science party last for?

  • If you've got 5 year olds and 6 year olds (5th and 6th birthday parties) best to keep things short and just go for the one hour party!
  • If you've got 7 year olds and 8 year olds (7th and 8th children's parties) then adding a module works great!
  • If they are getting a bit older like 9 year olds and 10 year olds (9th and 10th kids parties) - you can go nuts and add as many extra modules as you like!
