I recently came across an experiment that I feel would be an effective introduction activity on the processes that cause changes on Earth's surface. This experiement was a part of a book chapter, Rocks and Soil, from Bringing Outdoor Science In by Steve Rich. This text included many easy and interactive experiments. In this experiment, students will disprove any misconceptions they may have in regards to our steadily changing planet. The only materials necessary are: plastic containers, soil, card stock paper, scissors, toy cars, to buildings, twigs, and a worksheet that is found in the text. All of these materials are cheap and easily accessible if they are not already available in the classroom. This experiment is a great visual representation for lower elementary grade levels. It makes it easier for students to be able to later apply new material to the concepts that they experienced during the experiment. The attached worksheet would act as an assessment for students.
