• We are learning how light behaves in different conditions.

• We are learning how shadows are formed and affected by the distance between objects and light sources.

• We are learning how to plan and carry out fair scientific investigations.

• We are learning how to analyse data and explain results using scientific language and diagrams.

• We are learning how light technologies help us in everyday life.

Success Criteria:

• ✅ I can describe how light travels in straight lines.

• ✅ I can explain reflection, refraction, and absorption.

• ✅ I can draw and label ray diagrams accurately.

• ✅ I can plan and conduct a science experiment with a clear method and variables.

• ✅ I can present data using tables, diagrams, and scientific vocabulary.

• ✅ I can describe how technology uses light to improve our lives.

• Light is a form of energy that travels in straight lines.

• It allows us to see things when it reflects off objects into our eyes.

• Light can be natural (e.g. Sun, stars) or artificial (e.g. torch, lightbulb).

• Light travels faster than sound.

• Light behaves differently depending on the materials it hits.

• Light bounces off shiny or smooth surfaces.

• The Law of Reflection: The angle of incidence = angle of reflection.

• Mirrors reflect light in predictable ways.

• Reflection helps us in everyday life (e.g., mirrors, periscopes, road signs).

Your Turn!

Have a go at uploading a labelled Ray Diagram showing reflection.

• Refraction happens when light changes speed as it passes through different materials (like air to water).

• This makes objects look bent or distorted.

• Refraction occurs in lenses, water, and glass.

• It's used in glasses, microscopes, magnifying glasses.

Your Turn: Student Task:

• Post a photo of a refraction experiment.

  
  

• Dark colours absorb more light, light colours reflect more.

• Filters are coloured materials that absorb some wavelengths of light and let others through.

• If you look through a red filter, you see mostly red light.

• Objects appear different colours under different lights or filters.

Example:

• A red apple under a green light looks black because it can't reflect green.

Student Task:

• Try using different coloured cellophane filters and post your findings.

• Shadows form when light is blocked by an opaque object.

• The closer the light source, the larger and fuzzier the shadow.

• The further away, the smaller and sharper the shadow.

Student Task:

• Describe how shadow size changed and why.

• Light is used in:

  • Cameras – to capture images.

  • Torches – to see in the dark.

  • Solar panels – convert light to energy.

  • Projectors – send light through lenses to display images.

  • Lasers – used in medicine, measuring, or cutting.

• Student Task:

  • Find and post a photo of a light-using device.

  • Write how light helps that device work and why it’s useful.
