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.
