No Prep Plans: Year 8 Physics – Speed Calculations | Motion Investigation
Hands-On Cambridge Lower Secondary Science Companion
Grades 6–8

Bring physics to life with this engaging Speed Calculations: Motion Investigation lesson! Instead of simply solving textbook questions, students become scientists by measuring real-world motion, calculating speed, collecting data, comparing results, and presenting evidence-based conclusions.
Designed to complement Cambridge Lower Secondary Science, this investigation helps students develop a practical understanding of speed, average speed, and instantaneous speed through an exciting outdoor investigation that combines science, mathematics, and teamwork.

What's Included
- Teacher Directions (45–60 minute lesson)
- Student Research & Planning page
- Motion Investigation Data Sheet
- Investigation Report & Reflection page
