First Week of STEM Activities | 10 Low-Prep Engineering Challenges K–6

Start the school year with hands-on STEM challenges that are simple to prep, easy to explain, and realistic for busy classrooms. This First Week of STEM Activities resource includes 10 low-prep engineering challenges for grades K–6 using familiar classroom materials. Students build, test, problem-solve, collaborate, compare results, and improve their ideas while learning how STEM class works. The activities are especially useful for teachers working with short STEM blocks of around 30 minutes, making them a strong fit for the first week of school, introductory STEM lessons, or flexible engineering days. Along with the 10 challenges, the resource includes teacher guidance, student planning and reflection pages, kindergarten-friendly adaptations, STEM vocabulary, classroom expectations, tracking tools, and fast-finisher ideas.
