Pi-Day Catapult — Optimize Angle & Tension (Predict vs. Measure) | MS–HS NGSS
Description (NGSS included) Celebrate Pi-Day with a data-driven projectile challenge! Students tune angle and tension on a simple launcher, then predict vs. measure range and compute percent error. Teams graph Range vs. Angle (and optional Range vs. Pullback) and explain results with CER. 🧠📈 🔬 Investigate: hold one variable constant to fairly test the other. 🧮 Model: use a calibration shot or R ≈ (v²·sin(2θ))/g to predict. 📊 Analyze: compare predicted vs. measured; percent error

Build a Boat Challenge | STEM Engineering Project | Density, Buoyancy, and Force
Make density and buoyancy unforgettable with this hands-on Build a Boat Challenge! In this engaging STEM engineering project, students design and build a foil boat using one sheet of aluminum foil and test how many pennies it can hold before sinking. Students will apply density, buoyancy, mass, and engineering design as they create a blueprint, build their boat, test two trials, collect data, answer analysis questions, and improve their design. This fun and competitive activity ends with the e
