Stream table workshop at the University of Michigan Museum of Natural History

On Thursday, we visited the University of Michigan Museum of Natural History for a stream table workshop. We built and tested filters in small groups (and using different materials than our classroom filters), and spent time exploring a large stream table. We used it to observe water flow and erosion, and experimented with methods of curbing it.

The greenish tint to the right of this tiny ranch is food coloring, which represents agricultural waste. When the water starts flowing, it quickly finds its way into the river.

After our workshop, we spent some time exploring the museum in small groups. Everyone found plenty of things to investigate.
