This Physical Sciences unit addresses the concepts of light and sound and how they are sensed.

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.

Preparing for Learning

This Science unit provides excellent opportunities for cross-curricular integration. Look for ways to meaningfully integrate the content of the unit with other learning areas e.g. Literacy and The Arts.
Prior to commencing the unit, develop a classroom display which focuses on light and sound. Display word wall vocabulary and learning goals that the students will engage with throughout the unit to stimulate their learning. For examples of additional teaching resources to display in your classroom, browse the Light and Sound collection on the Teach Starter website.

The lessons and science experiments within this unit are structured in accordance with the scientific method. Ensure that the students are familiar with this process before commencing the unit. Alternatively, teach the method concurrently with the relevant lessons.

Some of the resources which accompany this unit plan will need to be prepared prior to teaching. For this reason, it is advised that teachers browse through all lessons before commencing the unit.
