Growing vegetables from food waste is a great lesson for kids and also makes great science experiments Teach students how to regrow food and pick a food to regrow as a class. Could use a food from a students leftover lunch.
For my herb garden. This one doesn't show you how to do it but looks like a good project to start! It's also great for a tiny patio or yard. Looks like the pots might be too small though. so, build frame bigger according to pot size preferred.
