Light Fantastic Unit Plan

This Physical Sciences unit addresses the properties of light. It explores the phenomena of reflection, refraction, shadow and more.

It consists of 8 lessons of approximately 60 minutes duration.

The sequence of lessons and suggested time frames should be regarded as a guide only; teachers should pace lessons in accordance with the individual learning needs of their class.

An assessment task for monitoring student understanding of the unit objectives is included and will require an additional lesson.

Teachers are encouraged to collect samples of students’ work throughout the unit to add to a learning portfolio. These can also be used to assess students’ understanding of the unit objectives.
