Living World

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

Bird Watch

Age 7 to 14 Challenge Level:

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

Food Web

Age 11 to 14 Challenge Level:

Is this eco-system sustainable?

Food Chains

Age 11 to 14 Challenge Level:

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

Terrariums

Age 11 to 14 Challenge Level:

Build a mini eco-system, and collect and interpret data on how well the plants grow under different conditions.

Big and Small Numbers in the Living World

Age 11 to 16 Challenge Level:

Work with numbers big and small to estimate and calculate various quantities in biological contexts.

Investigating Epidemics

Age 11 to 16 Challenge Level:

Simple models which help us to investigate how epidemics grow and die out.

Maths Is Everywhere!

Counting Dolphins

Age 14 to 16 Challenge Level:

How would you go about estimating populations of dolphins?

Big and Small Numbers in Biology

Age 14 to 16 Challenge Level:

Work with numbers big and small to estimate and calulate various quantities in biological contexts.

Bio Graphs

Age 14 to 16 Challenge Level:

What biological growth processes can you fit to these graphs?

Biology Measurement Challenge

Age 14 to 16 Challenge Level:

Analyse these beautiful biological images and attempt to rank them in size order.

Time to Evolve

Age 14 to 16 Challenge Level:

How many generations would link an evolutionist to a very distant ancestor?

Genetics

Age 14 to 16 Challenge Level:

A problem about genetics and the transmission of disease.

Natural Shapes

Age 14 to 16 Challenge Level:

How does shape relate to function in the natural world?

Robot Camera

Age 14 to 16 Challenge Level:

Could nanotechnology be used to see if an artery is blocked? Or is this just science fiction?

Solving the Genome Puzzle

Age 14 to 18

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

Age 14 to 18

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