Pine Cone Experiment

Can you close up a pine cone that is "open?"
First let ur kid/kids make their guess.
Then place open pine cones in a bowl of water.
After about a half hour the pine cones will be closed.

Each pine cone scale protects 1-2 seeds. When the seeds are mature, the pine cone falls off the tree and the pine cone scales dry out. As they dry, they "open" up and release the seeds. The scales are made that when they get wet they closed and when they are dry, they open.

I also like that the bins are smaller then the crates we were using so that the smalle…
