Ghost Hideout STEM Challenge | Halloween Engineering Activity K–1

Bring engineering and Halloween fun together with the Ghost Hideout STEM Challenge for kindergarten and 1st grade. Students are challenged to design and build a hideout for a ghost using simple classroom materials. Young engineers plan their ideas, build a structure, test their design, make improvements, and reflect on what worked. This hands-on challenge introduces students to the engineering design process in an age-appropriate way while encouraging creativity, teamwork, problem-solving, and persistence. It works well as a Halloween STEM lesson, seasonal engineering center, small-group activity, or whole-class building challenge. Why Teachers Will Love It - Designed specifically for kindergarten and 1st grade - Combines Halloween fun with meaningful STEM learning - Introduces the engineering design process - Encourages hands-on problem-solving - Includes planning before building - Gives students opportunities to test and improve - Encourages creativity and persistence - Works well individually or with partners - Uses simple classroom materials - Great for STEM centers - Easy to fit into a seasonal unit - Encourages student discussion and reflection - Keeps young learners actively engaged Perfect For - Kindergarten STEM - 1st grade STEM - Halloween STEM - October activities - Engineering challenges - STEM centers - Elementary engineering - Makerspace activities - Partner work - Small-group STEM - Seasonal enrichment - Classroom challenges - Homeschool STEM Skills & Concepts Students practice: - Engineering design - Planning - Building - Testing - Improving - Problem-solving - Creative thinking - Fine motor skills - Collaboration - Communication - Persistence - Following constraints - Reflection - Design thinking Materials Needed Materials can be adapted to what you already have available. Possible materials include: - Craft sticks - Straws - Paper - Cardstock - Index cards - Cups - Building blocks - Pipe cleaners - Tape - Glue - Scissors You can limit materials to make the challenge more difficult or give students a wider selection for more open-ended building. Estimated Time Approximately 30–45 minutes, depending on the amount of planning, building, testing, and sharing you include. Teacher Tip Keep the building materials simple and give students a clear goal rather than showing them exactly what their hideout should look like. The value of the challenge is in letting students make decisions, discover problems, and improve their designs.
