Summary: Good Earth Science/Erosion unit study
Comment: I've used this unit study twice now for homeschooling. The first time I was frustrated wading through the minutia of detail provided for setting up the experiments. The author gives way too much instruction on how to do things, but I guess he's aiming to make sure even the logically impaired can make the experiments work.
Beyond that annoyance, the concepts taught are wonderful. My 13, 11, 4 & 2 year old children have all enjoyed running the experiments and have learned a tremendous amount. Now as we drive through the countryside my children will point out meanderers, etc. to me. I've noticed that when they're playing outside in the mud and water they are using and talking about the principles of silt deposit, erosion, deltas and waterfalls that they learned from this unit study.
This unit study is simply wonderful at reinforcing earth science concepts through hands-on experiments and re-creation of a river...It addresses the California state science standards for erosion particularly well, if that is important to you.
