Yesterday in history we were learning that some things become fossils better than others. We made fossil sandwiches using a variety of things that we collected on our last nature day and squished them between pieces of white bread to see what would leave the best "fossil" imprint.
Here are a few pics although its kind of hard to see the imprints.
