Fall STEM Challenges | Apple, Pumpkin & Leaf Engineering Activities K–6

Bring seasonal fun into STEM with a collection of fall engineering challenges for grades K–6. This resource uses familiar autumn themes such as apples, pumpkins, and leaves to give students hands-on opportunities to build, test, improve, and solve problems. Students work through engineering challenges using simple classroom materials while practicing important STEM habits including planning, collaboration, testing, redesign, perseverance, and creative problem-solving. The activities can be used as stand-alone challenges, STEM centers, seasonal enrichment, early-finisher activities, or part of a larger engineering unit.

Estimated Time Most challenges can be completed in approximately 20–40 minutes, depending on grade level, available materials, and whether students complete multiple testing and redesign rounds. Teacher Tip For younger students, simplify the challenge by limiting the number of materials or completing the planning step as a class. Older students can be given additional constraints, measurement requirements, or redesign goals to increase the difficulty.
