Weathering and Erosion

The kids have been working on lots of Earth Science since the new year started. We began with the water cycle, moved into the layers of the atmosphere, studied the layers of the earth and are now starting to talk about the rock cycle. Mr. Finn introduced the concepts of weathering and erosion first as it's easy to begin to see that rocks can change. Seth here is checking out particles of sand and seeing how many different types of rocks and minerals are present. He really liked the special magnifier.
The kids got a chance to see all kinds of physical and chemical weathering around the world. They were totally blown away that ice, wind and water could create such incredible changes on the earth.
