Today we made our plastic lid bird feeders as an Earth day project. While we were making these the pan to press the lids into for seeds became a play pan for my 3yr old son. To start he was just having so much fun running his hands through it. We then added a truck and shovel. Anything you can shovel and put in a dump truck is a hit at my house! This is so simple and I am sure we could build upon this to make it bigger and better. However, sometimes simple is all that is needed to have fun!
