Video on the Physics of Food - No ordinary yogurt

Why is set yogurt a solid, while milk is a liquid? That's because it's a gel!

Discover the magic of yogurt-making in this video

The video here is just a cut of the...

Enzymes are Proteins

Enzymes are proteins that speed up the reactions by acting as catalysts. They increase the rate of reaction without being consumed or permanently altered by themselves. In Greek enzymes are divided into sections “En” which means “in” and second part is “zyme” means living. The study of enzymes is known as...

Spread of disease

This Core Maths resource enables students to explore various models of the spread of disease. 

The presentation has links to instructions for three activities:

  • a practical investigation using a die and counters to model the spread and decline of a disease and an activity sheet to...

Histograms

This is a series of interactive excel sheets that look at histograms.

The first sheet contains a histogram displaying a summary of time spent travelling to work. A new set of data can be generated at the click of a button. Alongside the graph tables calculating class width and frequency density can be...

Anthropometric Data

This resource from the Nuffield Foundation allows students to investigate relationships between anthropometric variables and write a report on their findings, which may include the use of scatter diagrams, lines of best fit, regression lines, and correlation coefficients. The spreadsheet contains anthropometric...

Seeing Temperatures

This activity allows students to investigate how images are produced from data streams by using first a spreadsheet and then an image-processing program. They then go on to see how the usefulness of such a monochromatic image may be enhanced by using lookup tables and calibration. The materials used focus on the...

The Safety Deposit Vault

This is an exercise with complex spreadsheets and mail-merged documents. It is based on an actual implementation in a vaut with over 1500 boxes of different sizes.

The simplified example uses nine boxes of three different sizes, each has the price for annual box rental.

Also recorded are the renters'...
