EARTH'S CHANGING SURFACE 4th grade students study Earth's changing surface, learning about the processes by which our mountains, plains valleys and canyons were created and are still changing. In LMC, students worked in partners to learn about the geology of a National Park, taking notes on its formation using the mind mapping tool - Bubbl.Us. With this knowledge, the partners wrote a script as if they were hosting a television geology show broadcast from the park to share information about how that park's incredible land was formed. Enjoy their information and the awesome green screen effect!
