Lesson Planning
Teaching
- Actively investigate how shadows change as the light source is moved.
- Take measurements and look for patterns in data to answer scientific questions.
Activities
- Make and attach a tissue paper screen to their puppet theatre in groups.
- Freely explore the effect of moving the light source on shadows in their theatre.
- Look for patterns and try to answer questions.
- Take accurate measurements of the length of shadows whilst controlling the distance of the light source.
- Observe a demonstration of light travelling in straight lines to help understand and explain shadow data.
Investigation - fair testing/pattern seeking
Investigate the effect of moving the light source on the size of shadows.
