IGCSE Physics: Core Practical — Investigating Motion | Edexcel Modular | Unit 1 | L4

This lesson covers spec point 1.5 — investigating the motion of everyday objects such as toy cars or tennis balls.

PowerPoint includes:
• Retrieval starter reviewing DT graph features and speed calculations
• Direct Instruction (I Do) — investigation method modelled step by step; equipment explained; ticker tape and light gate methods described; variables identified (distance, time); importance of repeat readings for reliability
• Guided Practice (We Do) — worked example calculating speed from ticker tape dot spacing; identify anomalous results from a sample data set; plan how to improve reliability
• Independent Practice (You Do) — students conduct the investigation, record results in the results table, calculate average speeds, and plot a distance–time graph from their data
• Review and Reflect — evaluation questions on accuracy, anomalies and improvements

Practical and Activity Sheet includes:
• Results table with distance intervals, three time trials and mean time
• Calculation section for average speed at each distance interval
• Blank grid for plotting the distance–time graph with labelled axes
• Evaluation questions covering repeat readings, sources of error and suggested improvements
• Full mark scheme for teacher use
