This file includes 6 STEM challenges. Our class uses them as home projects for our students to complete with their parents. There is a total of 6 because we have science fair projects and due to holidays, shorter months in school, so some months are combined. Our students LOVE doing these projects and are given time to work in small groups at school to work on their engineering design process. Our 2nd-5th grader STEM classes use these so they can be used for multiple grade levels!
