Lesson 3 - Biodiversity (and food chains)

This lesson is intended for students to learn about:

1. Biodiversity

2. Food chains and food webs - Constructing, analysing and interpreting 

Resources: Work booklet (Pages 7 -12) found here.


Open the SGSEPS Bush Blitz teacher blog and view as a class.

Biodiversity is the variety of all living things, including plants, animals, microorganisms and their interrelationships.

Think pair share task: Think to themselves about some words beginning with bio. Give each pair thirty seconds to write down every word they know beginning with the prefix ‘bio’ on the mini whiteboards. Share your answers with the class. Analyse ‘bio’ words and discuss as a class – what meaning do these words all have in common? They are all about life – plants, animals.

In pairs, students think of some synonyms for ‘diversity’ and write them on the other side of your mini whiteboard.

Still in pairs, students draft a meaning for the word ‘biodiversity’. Then use a dictionary to check your answer and write the definition in the glossary.

Use a Bush Blitz report (click here) to demonstrate the biodiversity in one of the locations of a previous expedition – turn to the list of species and skim-read through them with the students. Can the students make a similar species list of the animals and plants in the school grounds? Students will know many common names of animals they've seen before to be able to do this task.

Read through pages 7 and 8 of the booklet, then students complete pages 7 - 12 on food chains and food webs.
