Lesson details
Key learning points
- Light reflects from mirrors obeying the laws of reflection. Some reflects into our eyes causing an image to be seen.
- The image in a mirror is located where the light rays seem to have come from.
- A reflection appears to be directly opposite the object, the same distance behind the mirror as the object is in front.
- The image in a mirror is the right way up but is laterally inverted.
Keywords
Reflection - this word has two meanings: 1. the process of light 'bouncing off' a surface, 2. an image seen in a mirror
Image - a representation of an object
Laterally inverted - describes an image that has been 'flipped' horizontally (as occurs in mirror images)
Common misconception
Ideas about the nature of light and reflections are often taken for granted at this stage and simple misconceptions often persist, e.g. that all reflections appear to be on the surface of mirrors.
Give pupils practical experience of systematically investigating reflections, e.g. measuring the apparent location of a mirror image. Explicitly assess for misconceptions about the location and visibility of mirror images of an object.

We use learning cycles to break down learning into key concepts or ideas linked to the learning outcome. Each learning cycle features explanations with checks for understanding and practice tasks with feedback. All of this is found in our slide decks, ready for you to download and edit. The practice tasks are also available as printable worksheets and some lessons have additional materials with extra material you might need for teaching the lesson.
The assessment exit quiz will test your pupils' understanding of the key learning points.
Our video is a tool for planning, showing how other teachers might teach the lesson, offering helpful tips, modelled explanations and inspiration for your own delivery in the classroom. Plus, you can set it as homework or revision for pupils and keep their learning on track by sharing an online pupil version of this lesson.
