The Effects of Erosion
Working with our groups, we will get to perform a fun Erosion Experiment using:
a tray
sand
a cup
water
and a ruler!
We will collaborate with our groups to create a natural landscape on our tray. We will include mountains, hills, valleys, caves, pathways for streams, and more! Then, we will tape our cup to a ruler to rest on top of our tray. Next, we poke a small hole in the bottom of our cup, and fill it with water. Last step, we can't forget to prop our trays up to help the flow of water to the bottom of our landscape! We then get to observe how water changes the look of the landscape over time. Maybe our mountains will crumble, our valleys will change, our caves might collapse, etc.. We won't know until we try it!
Looking to interact with your child and learn about something Scientific at the same time? Take them to Torrey Pines Trails! There are multiple examples of erosion all around, especially when you get down the beach and can look at the cliffs! All around we see signs of erosion if we just learn how to take a look!
Keep Exploring,
