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

Ball Drop Test | Gravity and Acceleration Activity for Upper Elementary
The Ball Drop Test is a self-contained Montessori science activity designed for upper elementary (grades 4–6) students to investigate how gravity affects falling objects. This engaging work allows students to measure and compare the time it takes for a ball to drop from different heights and to understand acceleration due to gravity. Students will: Drop a ping pong ball from three different heights (0.5 m, 1.0 m, and 1.5 m) Use a stopwatch to measure drop time for each height Repeat trials,
