Grade 4 Science – Earth Models

Grade 4 are looking at forces that change the surface of the Earth. To get an idea of what the Earth is made of and how thin the crust is we built our own models.

We concluded that this meant that the crust is uneven around different parts of the world. We connected this with the thickness of mountains.
