This is a school-wide monthly challenge activity that I have developed for my own building. Each classroom will receive the materials needed to complete the challenge and classrooms will post their results in a central location. The classroom that has the most accurate predictions at my school wins a science gift basket. Teachers are able to extend the activity if they choose!
We get the gourds in sacks from our local grocery store.
We use the book, "The Ugly Pumpkin", with this challenge as a literature connection.
This is a great way to get whole building involvement in science! We use this monthly challenge in NOVEMBER!
