Cranberry Bog Boat — Buoyancy & Density STEM Challenge (Grades 3–12, NGSS Aligne

Created by

Make buoyancy click with a seasonal engineering lab: students design a small foil “bog boat” that carries the maximum mass (cranberries/coins/washers) before sinking. They plan, build, test in a water bin, record data, and iterate to optimize stability and displacement—perfect for stations or a full-period lab. What students do Plan & sketch under material/size constraints, predict capacity. Test in rounds, adding equal-mass items until failure; record max mass, freeboard, and failure mode.

Candy Cane Cantilever — Holiday Structures & Torque STEM Challenge (Grades 3–12,

Created by

Allison Smith

Engineer a festive cantilever that reaches the farthest overhang beyond the table edge—using only candy canes and limited tape! Students plan, build, test, and iterate while applying torque and center of mass ideas. Perfect for a high-engagement holiday lab, stations, or a one-period challenge. 🍬🧰 What students do 🧠 Plan & sketch: identify anchor vs. arm, place joints/tape, predict max overhang. 🧪 Test & measure: record trials, overhang (cm), stability (10 s), failure modes. 📈 Analyze
