Again this is a friend of mine. At 6 she had been told that eggs were chicken seeds. She reasoned that she could grow a chicken tree/plant with an egg from the refrigerator. (She had a lot of plants in her room that she took good care of, even at 6). She potted the egg in dirt and put the pot near the window in her room, watering it everyday and spraying it to keep bugs away. She learned the truth when her mother asked her what kind of plant was in the pot of dirt by the window (noticing nothing was growing there even after 3 months of watering/sunshine). Her mother got the biggest laugh when her daughter said she was growing a chicken tree.
