Lesson details

Key learning points

  1. Scientists carry out investigations to measure and compare the amount of friction created between different surfaces.
  2. The results from an investigation can be recorded in different ways, including tables and graphs.
  3. The findings from an investigation can be summarised into a conclusion.
  4. Objects experience more friction when moving across rough surfaces compared to smooth surfaces.
  5. Test results can be used to make predictions to set up further investigations.

Common misconception

All graphs can be used to present all types of data.

Examples given of different types of graph and sample data.

Keywords

  • Surface - The surface is the top or outside layer of an object or material.

  • Friction - Friction is a force that acts between surfaces.

  • Variable - A variable is something that can be changed, measured or kept the same in an investigation.

  • Conclusion - In a conclusion, scientists explain what the results show and what they mean.

This lesson should link directly to the previous lesson in this unit (lesson 3) whereby pupils planned how they are going to carry out a comparative test to find answers to the question: Do different surfaces create different amounts of friction?
