These dynamic resources provide guided lessons to integrate project-based learning into your science, technology, engineering, and math curriculum. Each unit provides background information for teachers and students and moves from teacher-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. Students will be challenged to work collaboratively, using a design process that helps them " step into STEM" with greater competence and confidence.
