These dynamic resources provide guided lessons to integrate project-based learning into science, technology, engineering, and math curriculums. Each unit provides background information for teachers/parents and students and moves from adult-directed activities toward more open-ended activities. The culminating activity in each unit allows students to design their own unique “invention” or conduct an experiment of their own creation. Kids will be challenged to work collaboratively, using a design process that helps them “step into STEM” with greater competence and confidence. Available in grades 3-6.
