No Prep Plans: Year 8 Physics – Distance-Time Graphs | Graph Analysis

No Prep Plans: Year 8 Physics – Distance-Time Graphs | Graph Analysis ProjectHands-On Cambridge Lower Secondary Science Companion
Year 8 / US Grade 7

Help students move beyond plotting points and begin thinking like physicists! In this engaging, hands-on lesson, students collect real motion data, create their own distance-time graphs, interpret graph features, and explain what a graph reveals about an object's movement.

Designed to complement Cambridge Lower Secondary Science, this investigation develops graph interpretation skills while reinforcing key concepts including speed, slope (gradient), constant motion, stationary periods, and changing speed.
