Outcomes
- Pupils understand the concept of reaction time, the factors that affect it and can recall one way of measuring reaction time.
Specification References
1.17 describe the factors affecting vehicle stopping distance including speed, mass, road condition and reaction time
Starter
Main Body of Lesson
- To guide the lesson, there is a power point presentation
- Make sundials; templates need to be printed onto card, a selection of templates can be found for inclined, equatorial, polar, cycloid polar, cross, equitorial, universal ring
- Make and use reaction timers; high ability worksheet and low ability, you may wish them to test their reaction time using a fake 'fiver'
- Discuss factors affecting reaction time. There is a really nice web site to simulate reation time and stopping distances.
Plenary
- Wordsearch - this can be found at the end of the power point presentation
Homework
- For their homework the pupils will need to use this web site and answer the questions in this worksheet.
Additional Information
Resources Required
- Sundial kits, images and videos of sundials, craft equipment
Textbook References

Skills Addressed
Safety/Hazards
- Craft equipment, particularly any knives or scissors, please see the risk assessment about using Knives and sharp objects
Notes
As an extension to the lesson work can be done on sundials:
- Pupils can explain how a sundial is used to measure time.
As a starter:
- Display images of different sundials, progressing through time; Show time-lapse video of sundial, an examples can be found here, here, here and here
