Light and Vision

Overview

This is the first lesson of a six-lesson unit entitled "Illuminating Art and Science" aimed at Year 6 students. The lesson introduces the fundamental concepts of light, focusing particularly on sources of light, reflection, and refraction. Students will connect these scientific principles with their artistic perception and understanding of how light influences vision and the way we perceive colour and shape.

Key Stage 2: Art and Design

• KS2 Art & Design: Develop their techniques, including their control and their use of materials, with creativity, experimentation and an increased awareness of different kinds of art, craft and design (Art and Design Programme of Study, Years 5 and 6).

Key Stage 2: Science

• Light (Year 6 Science Programme of Study):
  • Recognise that light appears to travel in straight lines.
  • Use the idea that light travels in straight lines to explain that objects are seen because they give out or reflect light into the eye.
  • Explain that we see things because light travels from light sources to our eyes or from light sources to objects and then to our eyes.
  • Recognise that light travels from a source to the eye and that shadows are formed when the light from a source is blocked by a solid object.

---

Learning Objectives

By the end of this 45-minute session, students will be able to:

• Define light and identify different natural and artificial sources of light.
• Describe key properties of light: reflection, straight-line travel, and refraction.
• Understand and explain how light affects visual perception and influences how artists use light and shadow.
• Engage in discussion and demonstrate understanding by providing examples of light in everyday life.

---

Success Criteria

Students will:

• State a clear definition of light.
• List at least three sources of light.
• Describe what reflection and refraction are in simple terms.
• Explain the importance of light for seeing objects and creating shadows.
• Participate actively in class discussion sharing observations related to light and vision.

---

Resources Needed

• A torch (flashlight) or LED lamp
• Mirrors and prisms or a glass of water (for refraction demonstration)
• White paper and pencils for quick sketches or notes
• Visual aids handout (bullet-pointed; dyslexia-friendly font, colour contrast)
• Images of famous scientists who studied light (e.g., Isaac Newton, Ibn al-Haytham)

---

Lesson Structure

1. Introduction (5 minutes)

• Starter question: "What is light? Where do we see it around us?"
• Gather initial ideas, noting student responses on a whiteboard or paper.
• Show a bright torch to illustrate an artificial source and point to a window as a natural source (the Sun).
• Briefly explain the definition of light as a form of energy that allows us to see and that travels in straight lines.

---

2. Explore Sources of Light (8 minutes)

• Discuss and demonstrate common sources of light:
  • Natural: Sun, stars, fire
  • Artificial: bulbs, torches, screens
• Use the torch to switch on/off; observe how light illuminates objects.
• Ask students to identify other sources in their environment.

---

3. Hands-On Reflection Activity (10 minutes)

• Using mirrors, let students explore how light reflects.
• Shine the torch light onto the mirror at different angles.
• Have students observe and describe the path of the reflected light.
• Sketch with arrows the direction of the light before and after reflection.

---

4. Introduction to Refraction (7 minutes)

• Demonstrate refraction with a glass of water or a prism.
• Show how light bends when it passes through a different material.
• Discuss briefly how refraction can explain phenomena such as rainbows or the ‘bending’ of a straw in a glass.

---

5. Discussion: Light and Vision in Art (8 minutes)

• Discuss how artists use light and shadow to create depth and perception.
• Show simple examples or ask students to think how light makes colours and shapes visible.
• Invite students to share any experience noticing shadows or reflections in artwork or nature.

---

6. Plenary and Recap (7 minutes)

• Quick oral quiz using success criteria questions.
• Recap key terms orally and in bullet points on the board.
• Distribute dyslexia-friendly handouts summarising the definitions and key points.

---

Differentiation Strategies

Learner Type	Strategy
Visual learners	Use images, diagrams, and demonstrations with mirrors and prisms
Kinesthetic learners	Hands-on activities with light sources and reflective surfaces
Dyslexic learners	Dyslexia-friendly handouts with bullet points, larger font, and clear spacing
EAL learners	Pre-teach key vocabulary using pictures and gestures

---

Extension Activity

• Task: Research a famous scientist who studied light (e.g., Isaac Newton or Ibn al-Haytham).
• Students to prepare a short fact file or poster for lesson 2.
• Encourage use of books or safe internet resources to find out about discoveries related to light.

---

Assessment

• Formative assessment through observation during discussions and practical activities.
• Assess students’ ability to correctly define light and describe reflection/refraction verbally.
• Review their sketches and explanations to check comprehension.
• Use the oral quiz at the end to consolidate learning and address misconceptions.

---

Teacher Reflection

• Did students link concepts of light and vision to artistic perception?
• Did all students engage actively with hands-on activities and discussions?
• Note any vocabulary that caused confusion for review and reinforcement in subsequent lessons.

This lesson blends science and art, aligns with the National Curriculum for England, and incorporates multisensory, inclusive, and differentiated learning approaches tailored for Year 6 learners.
