# Real World

This collection of STEM resources is based around real world topics.  Resources are listed in order of stage.

### Tom Learns to Cook

##### Stage: 2 and 3 Challenge Level:

If Tom wants to learn to cook his favourite supper, he needs to make a schedule so that everything is ready at the same time.

### Observing the Sun and the Moon

##### Stage: 2 and 3 Challenge Level:

How does the time of dawn and dusk vary? What about the Moon, how does that change from night to night? Is the Sun always the same? Gather data to help you explore these questions.

### Bird Watch

##### Stage: 2 and 3 Challenge Level:

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

### Terrariums

##### Stage: 3 Challenge Level:

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

### Chocolate Cake

##### Stage: 3 Challenge Level:

If I don't have the size of cake tin specified in my recipe, will the size I do have be OK?

##### Stage: 3 Challenge Level:

Is it cheaper to cook a meal from scratch or to buy a ready meal? What difference does the number of people you're cooking for make?

### Hmm ... When Should Tom Have Put the Rice on ...

##### Stage: 3 and 4 Challenge Level:

Creating a schedule to cook a meal consisting of two different recipes, plus rice.

### Speed-time Problems at the Olympics

##### Stage: 4 Challenge Level:

Have you ever wondered what it would be like to race against Usain Bolt?

### Bio Graphs

##### Stage: 4 Challenge Level:

What biological growth processes can you fit to these graphs?

### Natural Shapes

##### Stage: 4 Challenge Level:

How does shape relate to function in the natural world?

### Using the Haemocytometer

##### Stage: 4 Challenge Level:

Practise your skills of proportional reasoning with this interactive haemocytometer.

### Guessing the Graph

##### Stage: 4 Challenge Level:

Can you suggest a curve to fit some experimental data? Can you work out where the data might have come from?

### Alternative Record Book

##### Stage: 4 and 5 Challenge Level:

In which Olympic event does a human travel fastest? Decide which events to include in your Alternative Record Book.

### 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.

### How the Velodrome Found Its Form

##### Stage: 4 and 5

The Velodrome was one of the most striking buildings in the London 2012 Olympic Park. This article explores how mathematics helped design the iconic building and its track.
