This collection of STEM resources is based on the living world.  Resources are listed in order of stage.

Bird Watch

Stage: 2 and 3 Challenge Level:

Do you know which birds are regular visitors where you live?

Food Chains

Stage: 3 Challenge Level:

When a habitat changes, what happens to the food chain?

Terrariums

Stage: 3 Challenge Level:

Using the Haemocytometer

Stage: 4 Challenge Level:

Practise your skills of proportional reasoning with this interactive haemocytometer.

Solving the Genome Puzzle

Stage: 4 and 5

The human genome is represented by a string of around 3 billion letters. To deal with such large numbers, genome sequencing relies on clever algorithms. This article investigates.

Influenza Virus: It's All in the Packaging

Stage: 4 and 5

This article explores how researchers in disease dynamics are using mathematics to understand how the influenza virus replicates.
