Free CMY Cube Light Worksheet & Demo Guide

📚 Overview

This free printable resource helps students investigate the science of light and colour through a hands-on demo with a CMY Cube. Using coloured filters (cyan, magenta, and yellow), the activity demonstrates subtractive colour mixing as students observe how overlapping filters change the light that passes through.

Designed for Years 5–9, the resource includes a student-facing worksheet and a teacher guide with detailed prompts, setup tips, and discussion questions.

✅ This resource provides:

• A student worksheet with guided observation questions and colour mixing tasks

• A teacher guide with clear demonstration steps and science explanations

• Real-world links to subtractive colour mixing (e.g. printing, sunglasses, lighting)

• A quick and interactive 10–20 minute classroom activity aligned with curriculum goals

🧑‍🏫 Teaching Tips

• 💡 Visual Hook: Use the cube as a lead-in to your light or colour theory unit.

• 🧪 Guided Inquiry: Let students make predictions about colour outcomes before shining the light.

• 🌈 Cross-Subject Link: Tie in with art, media, or technology lessons to explore how colour behaves across disciplines.
