Natural Land Forms

We have just finished learning about volcanoes, earthquakes, glaciers, caves, and mountains. We've already studied volcanoes before, but they say science and history is repeated. In our case, it was sooner than later. You can see my volcano post here. We did the usual volcano activity of making a volcano and watching it explode. We also demonstrated with graham crackers the movement of tectonic plates. I came upon that idea from The Homeschool Den Blog. So this year, I just decided I was going to let the kids make their own natural land form, such as those we just learned about. During this project though, they had to build a model, find out a little research about it (including superlatives), and then diagram how their land form was formed. So my youngest goes with what we are learning about and she decides to do a mountain. My oldest, however, decided to do nothing that we just learned about. She decided to do a Redwood Tree, but I was okay with that - after all, as long as she is still learning and its a natural part of the earth. This is Earth Science we are studying. I thought they did pretty good and wanted to post pictures.
