The kids are cleaning up the playground and Michael and Tina turn it into a bit of a game. Barney comes to life and joins them. Luci meets up with the others, with a sore eye, and Derek explains to Barney that it's Earth Week at school and Tina explains more about it. This leads to Barney and the kids to explore ways to protect the earth including making musical instruments out of recyclable items, making three-cornered hats out of newspaper, and performing skits about preserving resources and reusing things. They even act out the story of Johnny Appleseed.
