Use this activity to activate your student's prior knowledge or assess their understanding of earth materials. This simple activity can help you gauge which students are already knowledgable in the subject and which students may have some misconceptions!
My husband and I created this resource to use in my own 2nd grade class. I used this as a pre-assessment tool for my science unit on Earth Materials. My students enjoyed hunting for the materials and I was able to assess my students' background knowledge on the subject before teaching the unit.
Use individually or whole class to suit your teaching needs! Enjoy!
