Why This Matters
Understanding light is fundamental to how we perceive our environment, from the colors we see to the way mirrors work. This lesson connects abstract concepts to students' everyday experiences, fostering a deeper appreciation for the science behind sight.
Objective
Students will identify light sources, explain reflection and refraction, and describe how light enables vision.
Materials Needed
The Science of Sight Slide Deck
Rainbow Spectrums Activity Sheet
Lightbulb Moments Cool-Down
Flashlights (1 per group)
Mirrors (1 per group)
Clear plastic cups & Water
Pencils & White paper/cardboard
Prep (20 min)
Review all generated materials and slide deck sequences.
Gather physical lab kits for small groups.
Set up stations for the 'Rainbow Spectrums' activity.
Instructional Sequence
10 min
Introduction: What is Light?
Begin with The Science of Sight Slide Deck to introduce light sources. Facilitate a brief discussion: "Where do we see light in our daily lives?" and "How would our world be different without light?"
15 min
Exploring Reflection: Mirror, Mirror!
Explain reflection using the slides. Divide students into small groups. Provide flashlights and mirrors. Instruct them to experiment with angles and observe where the light reflects. Ask: "Can you make the light reflect to a specific spot?"
15 min
Investigating Refraction: Bending Light
Transition to refraction using slides. Give each group a cup, water, and a pencil. Have them observe the pencil in the water from different angles. Ask: "Why do you think it looks bent?"
15 min
Activity: Rainbow Spectrums
Introduce Rainbow Spectrums Activity . Guide students to use a prism or cup of water with a flashlight to create a spectrum. Discuss observations: "What colors do you see? Why does white light break apart?"
5 min
Conclusion & Cool-Down
Summarize key concepts. Administer the Lightbulb Moments Cool-Down to assess understanding and reflections.

Light Lab Adventure
Think about it:
What is light? Where do we see it every day?
Teacher notes: Welcome students and introduce the topic of light. Ask them to share what they already know or wonder about light.
Sources of Light
Natural
The Sun
Stars
Lightning
Fireflies
Artificial
Lightbulbs
Flashlights
Screens (TV/Comp)
Neon Signs
Teacher Note: Discuss how we need light to see objects around us.
Bouncing Back: Reflection!
Reflection is when light bounces off an object.
Think about looking in a mirror – the light bounces off you, hits the mirror, and then bounces into your eyes!
🚀 Experiment Time!
Use your mirrors and flashlights! Can you make the light bounce to a specific spot on the wall?
Bending Light: Refraction!
Refraction is when light bends as it passes from one material to another.
Imagine a straw in a glass of water – it looks broken or bent because the light slows down and changes direction!
"Observe Your Pencil"
Look at your pencil in the cup of water from the side.
What do you notice? Why does it look shifted?
How Do We See?
01
Bounce
Light bounces off objects around us.
02
Enter
This reflected light enters our eyes through the pupil.
03
Process
Our brain processes the signals into shapes and colors!
Wait... what about colors? Where do they come from?
The Colors of Light
White light is actually made up of all the colors of the rainbow!
When white light passes through certain objects (like water or prisms), it can split into a beautiful spectrum of colors.
🌈 GET READY FOR AN ADVENTURE!
We're going to create our own rainbows with the Rainbow Spectrums Activity!

Objective
To observe how white light can be split into a spectrum of colors through refraction.
Materials
Cup of water, flashlight, white paper, prism (optional).
1
Water Refraction Rainbow
Place the cup of water on a surface near a window or flashlight.
Hold the white paper up to catch the light passing through the water.
Adjust the angle until you see a rainbow appear.
Tip: Move the paper closer or further away to focus the colors!
Observation: Sketch your rainbow below. What colors do you see and in what order?
2
Prism Play (If using a prism)
Hold the prism up to a light source.
Angle the prism so white light enters one side.
Hold the white paper screen to catch the light exiting the prism.
Rotate until a clear rainbow appears.
Observation: How is this rainbow similar to or different from the water rainbow?
Lab Discussion
1. What do you think is happening to the white light as it passes through the water or the prism?
2. Why do you think we see different colors, even though the light started as "white"?
3. Can you think of other places you see rainbows or light splitting into colors in the real world?
