Chalk Drawings and Olson's "Bean" Plant

This spring, Olson brought home a plant and then a few sprouted beans from school. He told us they were all bean plants so we took them outside and planted them by the house. One of them grew very tall and the other ones didn't. The kids were quite amazed at how this "bean" plant was growing. Finally when it developed a large head with yellow petals, they realized it was no bean plant at all but a sunflower.
