Learning Intention
Students will investigate how light travels in a straight path, and describe how shadows, reflection and refraction occur.
Australian Curriculum
AC9S5U03
Identify sources of light, recognise that light travels in a straight path, and describe how shadows are formed and light can be reflected and refracted.
Teacher Notes
A torch, mirror and glass of water turn this into a hands-on demonstration before students complete the written reasoning.
Skills Practised
- Physical Sciences
- Mathematical/critical reasoning
- Real-life application
- Self-checking against success criteria
Why This Worksheet Works
- Connecting reflection, refraction and shadows in one worksheet mirrors how the curriculum groups them.
- Simple, safe hands-on demonstrations (torch, mirror, water) make abstract light behaviour visible.
- Diagram-based questions build scientific explanation skills, not just definitions.
- Written to AC9S5U03, so it drops straight into a Year 5 physical sciences lesson.
