In this week's spotlight: an environmental engineering and Earth science project and hands-on activity that lets students and families explore what's happening when a landslide occurs. With a simple homemade model using a clipboard and pennies, students simulate how the angle of repose changes with different hill mass and slope surfaces. What happens when you change the materials used in an object sitting on a slope? What's going on with gravity on a slope? At what point does sliding begin and why? Get hands-on to find out!
Teachers: A classroom-friendly version of this Earth science and geology science exploration is available! Science Buddies Classroom Activities offer both educator and student guides to help teachers integrate hands-on learning in the classroom. The Landslides: What Causes Rocks to Slip and Slide? classroom activity takes under 30 minutes to set up and perform—about 10 minutes of student time. A simple setup using pennies and clipboards brings the relationship between gravity, materials, slope, and angle to life for students as they learn more about landslides.
