Students got to see actual erosion occur. Sand was placed in a stream table and water was released on two separate instances. The first water acted like a rain from it release. A river and delta were created. To further the concept of erosion, the same amount of liquid was dropped except this time it was released much quicker, simulating a flood. Besides a river and delta forming, students witnessed canyon as well being created. Another observation to help the understand the concept of erosion, was that larger pieces of sand did not much as far as the smaller pieces of sand. Students mastered the fact that the more force an object has like amount, speed and size will result in greater erosion.
I hope you enjoy learning how the garden changes throughout the school year.
