21 June 2012 Various experiments

Today I made a rubber band ball and checked how bouncy it was. I covered a Bakugan with the rubber bands.

We also wanted to see how lentils and kidney beans will sprout. So we soaked three types in a plate and covered them with cotton soaked in water. I will check every day to see how they grow.

This is after I soaked them

We wanted to see how water and oil will mix together and whether water is heavier than oil. I think oil is heavier than water but we will find out tomorrow. We coloured the water Green to help us see it properly.

The last experiment we did today was I covered 10 screws and bolts with a little bit of water and kept it in a plastic container. I want to see how long it takes for them to rust.

I took the photos myself.
