Protecting our eyes from the Sun: plan

Introduction to light and shadows

Unit Summary

This unit explores the nature of light, recognising that light is needed to see and that dark is the absence of light. It covers how light reflects and shadow formation. The unit emphasises practical tests, observations, accurate measuring, and using evidence to support findings.

Lesson Summary

You will learn to plan how to investigate sun protection.

Key Notes

  • The Sun provides heat and light and is necessary for living things to survive on Earth.
  • Too much ultra violet (UV) light from the Sun can be dangerous.
  • There are ways to protect our eyes from the Sun.
  • It is not safe to look directly at the Sun, even when wearing sunglasses.
  • Scientists ask questions and plan different types of enquiries.

Vocabulary To Learn

  • Sun: The Sun is a star and is at the centre of our solar system.
  • protect: To protect something is to keep it safe from harm.
  • damage: When something is spoiled or harmed, it is damaged. If you damage something, it will not work well and may be broken.
  • ultraviolet (UV): Ultraviolet is a type of light produced by the Sun that human eyes cannot see. It can harm a human's skin.
  • plan: A plan is a method that maps out the steps that will be taken during an investigation.

Common Mistakes To Avoid

  • It is safe to look at the Sun on a cloudy day or when wearing sunglasses.

3 Quick Questions (With Answers)

1. Explain the scientific idea in this lesson using two key points.

The Sun provides heat and light and is necessary for living things to survive on Earth. Too much ultra violet (UV) light from the Sun can be dangerous.

2. Define this scientific word and use it in context. 'Sun'

The Sun is a star and is at the centre of our solar system. Include the word in a full scientific explanation, not as a single label.

3. Correct this common scientific misunderstanding.

Mistake: It is safe to look at the Sun on a cloudy day or when wearing sunglasses. Correction: Clear explanation that pupils should never look at the Sun, even if wearing sunglasses or if the weather is cloudy.
