Elaine, That is such a nice experience you're providing for the kids. I''m a retired Elementary Principal, and we used to have some gardening experiences for our students too, only we had to do it as part of summer school, as by now most of the garden is finished for the year. Can I make a friendly suggestion? Wouldn't it be a great learning experience to let the kids brainstorm some solutions to this problem rather then have the adults solve it for them? I'm sure they would have a good time coming up with solutions, and experimenting with them. They could also come up with ways to fund any projects they decided to do. Thinking and problem solving skills are by far the most important things we can teach kids, and the only way to teach that is to give them opportunities to practice them. Experiment, and learn from their mistakes. The important thing in this project is for them to learn, not to get a huge crop of anything. Just my 2 cents worth. Have fun!
