Collision Course Visual Guide
A one-page visual anchor chart for 9th-grade physics. Explains Newton's 3rd Law, momentum (p=mv), and Conservation of Momentum. Now includes a comparison between Elastic and Inelastic collisions.
Crash Lab Worksheet
An enhanced 4-page student worksheet featuring student-designed scenarios, higher difficulty challenge questions, and a predictive math section where students calculate the outcomes of inelastic train collisions. Optimized for conceptual depth and practical math. Revised to use "Grocery Store" examples and fixed page break overflows.
Crash Lab Answer Key
Expanded 4-page answer key for the Crash Lab Worksheet. Now includes worked solutions for student-designed scenarios, challenge questions about asteroids and satellites, and the predictive math for train engine couplings. Revised for renumbering, unit consistency, and scientific terminology.
Collision Course Teacher Guide
Teacher's facilitation guide for the Collision Course lesson. Updated to include instructional strategies for teaching the difference between elastic and inelastic collisions.
Collision Momentum Slides
A presentation deck demonstrating the Law of Conservation of Momentum. Now includes a comparison between Elastic (bouncing) and Inelastic (sticking) collisions, showing that total momentum is conserved in both cases. Revised for visual clarity and contrast.
