Neil Downie's books of Saturday Science Projects are a great source -
there are three, titled by experiment (I can't recall the whole title,
but an Amazon search on the first part should get it for you): Vacuum
Bazookas...,  Ink Sandwiches..., and Exploding Disk Cannons...

These have been tested with kids, so they are reliable and most of them
require only ordinary materials.

> Dear Colleagues,
> 
> Marianne here from Galway Atlantaquaria in Ireland. We hold 
> Children's Science Workshops every Saturday, and the most 
> popular component is alway the science experiments. I've run 
> the workshop for a while now with the same 6-7 experiments, 
> but now I'd like to change the content of the workshop to 
> encourage (hopefully) some repeat visits!
> 
> Does anyone have ideas for some fun science experiments, 
> water-related or not, marine or not, that I could use for the 
> workshop? The kids are 7-12 years old. the experiments we've 
> done until now are the following: Make a sand filter, density 
> gradient in salt and fresh water, design a boat, mussel 
> filtration, time a wave, water quality testing, and launch a 
> rocket (which has nothing to do with marine science, it's 
> just fun!). I'd also be happy to share the instuctions for 
> these experiments with anyone who's interested.
> 
> Thank you for your help,
