First you find some nice sized flat leaves that float well and make a prediction on how many rocks it will take to sink the leaves.
Then start putting rocks onto the leaf. The girls had fun experimenting with different sizes of leaves to find out how that effects the results.
Watch the leaf sink!!!!
It is now 2 hours after I have forced the girls outside and we are still out in the sun. They went for a long bike ride, played with water, were beavers building dams in the mud and now are tracking down a frog attempting to catch it!! So I sit out in the front yard blogging in the sunshine! Have I mentioned how much I love my laptop????
