How do rain gardens affect how much water soaks into the ground? How to teach them about rain gardens;
What I will do in the water fair is compare normal ground and rain garden ground. I will focus on how the garden catches water when it rains, at what rate, and how the water soaks into the ground. The lessons may also compare the different surfaces water can run off of and what environmental problems it can cause. I will research lessons that would be effective for my topic, and pick one to conduct at the fair. One that I have looked into so far is having two separate trays one with just soil and another with soil and some plants, and then pour water and proceed to make observations on how the water gets absorbed differently between the two trays. My data collection will be based on the lesson plans that I find on credible and reliable sites.
