This kit makes complex problems like soil erosion understandable and meaningful to younger students. The student book The Disappearing Earth is written in comic book format to engage young readers. It ties closely with the accompanying science experiments. Students can participate in hands-on activities making mudslides, building worms, creating rainstorms, and learning about the interactions of soil and water on our planet. A new book, Beneath the City of Ooze, has been added to the kit. It takes readers into our storm sewers to teach how sewers can carry pollutants to our lakes, rivers, and wetlands.
