The Stream Table.
After lunch we headed to the stream table. The stream table is a large abiotic looking ecosystem. With a water pump it pumped water from a faucet into a pool shaped bin half filled with sand. Before the water started to run we shaped an inch wide path along the sand and made a cut off cliff. We turned the water on, and it followed the path to the cliff and ran off. This taught us how in nature the water will erode the land, take its own separate paths to the run off, and can intertwine with the other paths to make a larger river. We used this knowledge afterward when we visited the dam.
