Straw Bales

We have added "straw bales" to our models. We place the straw bales in culverts or where the water is running off the land and into a water body. The "bales" are tiny rectangles of yellow sponges.

Silt Fences

We have added "silt fences" at the edge of the construction site. The "fences" are made of black electrical tape (about 7 inches long) with toothpicks used for fenceposts.

Tips

Use modeling clay to attach pieces to your watershed model.
