We tried another experiment from the Eco Science kit yesterday. The idea was to discuss pressure and demonstrate how a submarine works. The instructions stated to fill the dropper 2/3 full then drop it in the bottle full of water. With the right amount in, the dropper should sink and float and the bottle is squeezed and released.
However it didn’t quite go according to plan unfortunately as the dropper seemed to go from too much water to too little in just one drop. After a frustrating half hour or so of emptying and refilling the bottle in order to get the dropper out and try again it got rather tedious so we finally gave up.
She then enjoyed designing her own experiment and exploring the resources her own way instead.
She was very disappointed it did not work out and we were both rather frustrated by the end. Think we would rather have given this one a miss!
