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

Paper Helicopters: Rotor Length vs Fall Time — Data Tables + Scatter Plot | 3–12
🚁 Forces & Motion meets Data Literacy. Learners design three rotor lengths (L1–L3), collect 3 trials each from a fixed drop height, compute averages, and graph Rotor Length vs Time on a scatter plot. Middle/high school extensions add best-fit analysis and force/drag reasoning. What’s Included Student Pack p.1: Background, IV/DV/controls, criteria, sketch box with dimension callouts Student Pack p.2: Three data tables (L1–L3), large scatter-plot grid, best-fit guidance, CER prompts Teache
