This is fun activity to add to your rock unit. The set, by Sara Ipatenco, contains all the printables you need to do an eggshell geode lab in your classroom. The set includes a “My Eggshell Geode Lab” booklet that includes a cover page, a page to list the materials, a page to write down the set-up, and a page for writing and drawing observations. You can make the book as long or as short as you want, depending on how many times you want your students to observe. The set also includes instruction cards and cute eggs to use as name tags to label each student’s project. Enjoy!
