IGCSE Physics: Distance-Time Graphs | Edexcel Modular | Unit 1 | L3

This lesson covers spec point 1.3 — plotting and explaining distance–time graphs.

PowerPoint includes:
• Retrieval starter reviewing the speed equation and scalar/vector distinction
• Direct Instruction (I Do) — distance–time graph features explained with annotated examples; gradient = speed; horizontal line = stationary; steeper gradient = greater speed; how to calculate speed from gradient
• Guided Practice (We Do) — describe the motion shown in a three-section DT graph; calculate speed from a given gradient; identify the fastest section and justify using gradient comparison
• Independent Practice (You Do) — multi-section DT graph interpretation; sketch a DT graph from a written description of a journey; calculate average speed from graph data
• Review and Reflect — 3 MCQs and exit ticket graph description

Activity Sheet includes:
• Labelled distance–time graph for interpretation questions
• 10 exam-style questions covering graph description, gradient calculation, motion identification and graph sketching
• Stretch question requiring students to compare two journeys on the same axes and explain the differences
• Full mark scheme for teacher use
