This resource is part of a collection of Nuffield Maths resources exploring Calculus. The demand is roughly equivalent to that in GCE A level.

Students solve differential equations to find functions to model the value of a car in terms of its age. Then they compare their results with real data.

A function is defined so that f(xy) = f(x) + f(y) for all positive integers x and y. Students are given the value of f(10) and (40) and are challenged to determine the value of f(500).

In each student worksheet contains different values for f(10) and f(40) but for...

A Catalyst article about the naming system used for biological species, devised by Linnaeus. The purpose of biological names is investigated and the article also explains how the naming system works.

This article is from Catalyst: Secondary Science Review 2009, Volume 19, Issue 3.

The aim of this investigation is to find the value of a number of resistors using a Wheatstone bridge.  Although this is an historical piece of equipment that has been superseded by modern methods it provides an excellent way to understand potential difference in circuits.

This Core Maths activity includes four problems that remind students of familiar probability theory concepts, enable discussion and highlight possible misconceptions.

This Catalyst article looks at agricultural plants, that are prone to many diseases, and scientists who develop new techniques to fight these diseases.

The video asks students to predict when a bungee jumper experiences maximum acceleration.  The answer is at the very bottom of the jump.  This is often counter-intuitive as the velocity at this point is almost zero. 

However, acceleration is the rate of change of velocity over time, a = ^Δv/_Δt...

This Catalyst article explains why there are many anti-bacterial drugs but few antivirals. There are millions of bacteria everywhere – on skin, in the gut, and on food. Bacteria have been troubling human beings for as long as they have been around, so a lot of effort has been directed into finding ways to fight...

Produced by the Royal Observatory Greenwich, this booklet guides students to use Einstein’s mass-energy equivalence equation to determine when the Sun will become a red giant. Included is an online video that discusses how we can determine how old the Sun is. Details on the relationship between mass and energy in...

This podcast from the Natural Environment Research Council's (NERC) Planet Earth Online collection looks at how scientists are using fish scales to figure out why the UK salmon population is falling; and how carbon dioxide emissions from power stations could be used to make household bricks.

Salmon numbers...

Produced by the Learning Skills Improvement Service (LSIS), this case study tackles the theme of progression through STEM subjects. By Newham Adult Learning Service, it describes an action research project that aimed to capture progression and learner voice data from a sample of learners who had recently completed...
