Our archaeological dig

Today, we did an archaeological dig. It might not look like it's for fossils, but it is what palaeontologists sometimes do. Usually, you dig for something that's already there, but we buried things, and then, in 8 weeks, we're going to dig them out and see if they've changed. We buried six things - three of them were organic, and three of them were inorganic. Organic means they were alive, and inorganic means they weren't alive. Our organic things were a banana skin, a hyacinth leaf and a piece of paper (paper is organic, because it's made from trees). Our inorganic things were a fossil, a lego brick and a coin. The fossil was once alive, but now it is stone, so it's inorganic.

For each one we had to say what colour it was, draw a picture, measure it, and say what it felt like. And when we dig them up, some of them might have changed, and some of them might have not changed.

Then we went outside. We put sand in a plastic box, and we made one layer, and we put two things on it. And then we made the next layer, and then we put two things on, and then we made a layer of soil, and we put two things on it, and we put more soil on top.

Now it's finished. It's going to stay in our garden for eight weeks, and then we'll tell you if anything's changed. If you want to make your own archaeological dig, you can use the information that we used: http://downloads.bbc.co.uk/history/handsonhistory/dig_family.pdf

    Hello, my name is Toby. I am five years old, and I want to be a palaeontologist. I really like fossils, so I'm writing down everything I do with fossils! My Mummy is doing the typing until I'm a bit older, but she writes everything I say.
