Light and reflection

Pupils who are secure will be able to:

• Compare sources of light and explain how the eye is protected from light.
• Describe how light travels and how we see luminous and non-luminous objects.
• Recall factors that affect the size of a shadow and describe how the distance between an object and the surface its shadow is cast on affects the size of the shadow.
• Use ray diagrams to explain why shadows change size and why the shape of a shadow matches the object that cast it.
• Recall what happens to light when it reaches a smooth mirror surface.
• Identify the incoming and reflected rays and describe the relationship between their angles.
• Use mirrors to make a working periscope and explain how a periscope works using ray diagrams.
• Recall a range of uses of mirrors and reflection and describe how a mirror reflects light in different situations.
• Explain how light is reflected using knowledge of light and reflection.

When working scientifically, pupils who are secure will be able to:

• Make observations about the properties of light.
• Use my observations as evidence to support conclusions about light. 
• Draw ray diagrams.
• Pose testable questions in response to observations.
• Record my measurements as a line graph.
• Use my line graph to extrapolate data and make predictions about missing values.
• Recall various jobs or inventions that use mirrors and reflection.
