This is an introduction to a 3-6 unit on Weathering, Erosion and Deposition. This activity stands alone as a engaging introduction to Weathering. Students need no prior knowledge as this exciting PPT lures them to wonder and ask questions - which is what we want them to do in science! It is followed by a series of activities that will set in their minds the difference between mechanical (physical) and chemical weathering. This can be used with elementary,middle and high school to introduce your already designed unit or be on the lookout for fun, simple, inexpensive activities we know you & students will love!
