Making Fossils

Today we did a little project that the kids LOVED. I had done this in my grade four classroom a few years ago, but it worked great with my young kids too. This fossil recipe is very easy, and they turn out surprisingly well.

You will need:
1 cup of used coffee grounds
1/2 cup of cold coffee
1 cup of flour
1/2 cup of salt

That's it!

We mixed the ingredients up in  a bowl. Our mixture seemed a bit dry so we added a tiny bit more coffee.

Then we rolled the "dough" into balls...

...and pushed it down to make  a perfect surface for our fossilized item!

I told the kids to go into the toy room and choose some items that would make good fossils. They decided on this lion,

a building block,

...and some toothpicks (those were in the cupboard, not in the toy room. I know what you were thinking - "She lets her kids play with toothpicks?!")

Number Two decided on an elephant and a car. Not so sure how these ones will turn out, but he was sure having fun!

Our fossils are now drying and should lighten up quite a bit by tomorrow. It takes up to two days for them to harden, so we'll see if the kids can actually leave them to dry for that long.

We'll be back soon!
