These were some of the ideas for projects at my son's gradeschool science fair at the end of January. There should be more, somewhere....
I just made a personalised Cartesian Diver for Valentines day, and it turned out awesome, so I am raving about it atm.
Try it, it is basically a water bottle (I used a glass wine bottle, making it infinitely harder to test), and a small object that barely floats. What you do is fill it with water, put the object in, put the cap on tight and squeeze, and the object should fall. The physics aren't too hard to understand, basically when you squeeze the air in the object compresses and so it has less buoyancy.
A tomato ketchup sachet would usually work, if you don't want to make a small object, although it would be a good experiment if you got a large bottle and put lots of different objects in, and see if anything sank more quickly than others. If you do make your own objects, try making an 'impossible bottle' scenario where the object cannot fit back through the neck of the bottle, or amke it look good. Making something that both works and looks nice is challenging and frustrating, but definitely pays off!
