Year 3 – CBOL Session 11: Light (Reflection & Spectrum)

This fully resourced outdoor science session explores the properties of light — how it contains all colours and how it travels in straight lines before reflecting off surfaces.

Through structured team challenges and a practical torch investigation, students develop deep conceptual understanding of reflection.

🌈 Core Learning:

Students understand:

• Light travels in straight lines
• Light contains the 7 colours of the spectrum
• Reflection is when light bounces off a surface
• Smooth, shiny surfaces reflect best
• Rough, dull surfaces scatter light

Spectrum Order (ROYGBIV):

Red
Orange
Yellow
Green
Blue
Indigo
Violet

🚀 What’s Included:

✔ Full Teacher Guide with session script
✔ Spectrum Colour Stacking Challenge Plan
✔ Reflection Keyword Cards (Light Source, Beam, Straight Line, Surface, Mirror, Reflection)
✔ Ray of Light Swamp Relay Instructions
✔ Torch Reflection Investigation Worksheet
✔ Equipment & Setup Checklist
✔ Safety Reminder Guidance (Sun safety included)

🔬 Investigation: Reflection Test

Enquiry Question:
Which materials reflect light the best?

Students:

• Shine a torch at different materials
• Angle surfaces to bounce light onto a target
• Observe brightness
• Score reflections (1–5)
• Compare foil, plastic mirror, wood, fabric
• Draw conclusions using scientific vocabulary

They practise:

• Prediction
• Controlled testing
• Careful observation
• Comparative analysis
• Evidence-based explanation

This lesson develops:

• Vocabulary precision
• Spatial reasoning
• Scientific enquiry structure
• Collaborative teamwork
• Conceptual physics understanding

And most importantly…

Children leave understanding that light doesn’t just appear.

It travels.
It reflects.
It follows rules.
