Click "edit" and then copy-and-paste the text below into your new lesson plan.
Contents
Outcomes
- Pupils can explain how a sundial is used to measure time
- Pupils understand the concept of reaction time, the factors that affect it and can recall one way of measuring reaction time
Specification References
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
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
Website References
- to use some of the sundials you will require the latitude, you can find this at this not so nice web site or just stand outside and use a GPS.
- Or ask Alby: Broadfield is at 51° 14' 11.27"N (0° 11' 32.83"W).
- excellent sundial website with all resources can be found at
Skills Addressed
Safety/Hazards
- Craft equipment, particularly any knives or scissors, please see the risk assessment about using Knives and sharp objects
Notes
None
