Here is an awesome FREE on-line resource for anyone who has kids and wants to include them in the gardening experience!
The National Gardening Association has a website designed entirely around educating kids using the garden. They have tons of resources that could be a great resource for home schoolers, teachers or parents wanting to include gardening in education. I'm looking forward to checking out some of the "Classroom Projects" to see there is something I can use in our home this summer! :)
