Exploring the Science of Light
Key Stage 2 / Ages 7-11 / Intermediate
Instructions: This worksheet will guide you through various activities to understand the properties of light. You will explore how light travels, how we see, and the concepts of reflection and shadows. Follow the instructions for each activity carefully.
Understanding Light Paths
Light travels in straight lines. Draw a line to show how light travels from the sun to the earth. Then, answer the question below.
Draw a straight line from the sun to the earth. How does light travel?
Reflection and Mirrors
Explore how light reflects off surfaces. Draw lines to show how light reflects off a mirror. Then, answer the question about the angle of reflection.
Draw lines to show light reflecting off a mirror. What is the angle of reflection if the angle of incidence is 30°?
Shadow Investigation
Shadows are formed when an object blocks light. Use the diagram to predict where the shadow will fall. Then, explain why shadows change size.
Draw where the shadow will fall when the light source is on the left. Why do shadows change size throughout the day?
Refraction of Light
Refraction occurs when light passes through different materials. Draw how light bends when it enters water. Then, answer the question about the bending of light.
Draw the path of light as it enters water from air. Why does light bend when it enters water?
Colour Mixing with Light
Discover how different colours of light mix to form new colours. Use the colour wheel to show what happens when red and green light mix.
Draw the result of mixing red and green light. What colour is formed when red and green light mix?
How We See
Light enters our eyes and allows us to see. Label the parts of the eye involved in seeing. Use the diagram below to help you.

Light Sources
Identify different sources of light. List at least three natural and three artificial sources of light.
Natural sources:
Artificial sources:
Exploring Shadows
Conduct a simple experiment to see how shadows change. Place an object in sunlight and observe its shadow at different times of the day.
Record your observations of shadow changes throughout the day. Morning:
Noon:
Afternoon:
Activity 1: In straight lines
Activity 2: 30°
Activity 3: Because the angle of the light source changes
Activity 4: Light slows down and bends
Activity 5: Yellow
Activity 6: Cornea, Iris, Pupil, Lens, Retina, Optic Nerve
Activity 7: Sun, stars, fire ; Light bulb, torch, streetlight
Activity 8: Answers will vary based on observations
