Energy: Light and shadows
Unit outcomes
Pupils who are secure will be able to:
- Recall examples of light sources, objects that do not give out light and that darkness is the absence of light.
- Describe ways to protect eyes from harm.
- Describe what happens when light reflects, give examples of reflective surfaces or materials and describe factors that may affect the quality of a reflected image.
- Describe how shadows form and identify patterns between groups of materials and the shadows produced.
- Recall factors that affect the way a shadow appears, including what causes shadows to change throughout the day and factors that change the size of a shadow
- Describe the pattern of changing shadows throughout the day.
- Describe how the light source’s distance affects the shadow’s size.
- Explain why a particular material is appropriate to make a shadow puppet and use knowledge of shadows to animate it.
When working scientifically, pupils who are secure will be able to:
- Recall what information needs recording to decide the number of columns in a results table and suggest suitable headings for the results table.
- Record information in the correct columns.
- Identify if a question is testable, explain why and plan ways to answer a testable question.
- Identify and explain why something is an advantage or disadvantage of a method and suggest an improvement to the experiment.
- I can describe patterns in data and quote values as evidence of patterns in data.
- I can identify odd results that do not fit the pattern.
- I can use patterns to make predictions for missing data.
Please note that Kapow Primary Science lessons are designed to be 1 hour and 30 minutes long, to reflect the requirements of a core subject.
