Sujith's job as an environmental consultant enables him to make a difference and improve our environment. He consults on how to lessen air quality issues, noise pollution, green house gases and climate change.

In this learning episode, from the Institute of Physics, students look at the forces involved when one vehicle impacts another object. This can be used to illustrate the forces, acceleration and deceleration involved. It considers the effect of the distance over which a force acts rather than the time of action of...

This learning resource, from the Institute of Physics, introduce students to Coulomb’s law which describes the force between two charges. The activities compare this to the way Newton’s Law of Universal Gravitation gives the force between two masses. Both follow the inverse-square law. The difference being that an...

NASA's Gamma-ray Large Area Space Telescope, or GLAST, is a space-based telescope that looks at the universe in the gamma ray wavelengths. This telescope will study known sources of gamma rays in detail but will also discover thousands of new gamma-ray sources in its five-year mission. This resource has an image of...

The Nuffield Foundation provide this activity which uses graphical methods to find a suitable model to connect two sets of data. There are a variety of ways in which the data could be used, depending on the focus required. It is possible to use a log graph to find an exponential model, which is the intended focus...

Five squares are given. Each square contains a pattern of squares or triangles that become smaller and smaller until they are infinitely small. The challenge is to work out what fraction of each square is shaded. The challenge provides an introduction to the concept of geometric progressions and the idea of a limit...

This simulation allows students to visualise the gravitational force that two objects exert on each other. It is possible to change properties of the objects in order to see how that changes the gravitational force between them.

The simulation can be used to:

*Relate gravitational force to the masses...

In this resource the head of a circular snowman rolls around its circular body to make one trip back to where it started. The ratio of the diameters of the circles is given. The challenge is to find how many times the head will revolve throughout the journey, and find a general rule.

The resource contains a...

Carom Maths provides this resource for teachers and students of A Level mathematics.

This presentation demonstrates how the interesting idea of Hikorski triples was developed from writing a GCSE Equations worksheet in 2002. The triples are identified as (p, q, pq+1/p+q).

The activity is designed to...

Origami squares are shown with different colours on each side of the paper. Two folds are made and then a hole is punched through all of the layers. The challenge is to determine where the holes appear when the squares of paper are unfolded. This resource is suitable for Key Stage 3 and could be used as an...

This video shows people’s misconceptions regarding the age of the Earth. It shows how imagining the difference between a million and billion is very difficult for people to do.

The video uses an arm span to model the age of the Earth and shows how recent in the Earth’s history the evolution of more complex...

Keys to Chemistry Book 1 was the basis for an introductory course of chemistry in secondary school. The book is a reflection of chemistry teaching in the 1970s, following the Nuffield developments in the previous decade.

Contents

1. What is chemistry?
2. Separating mixtures
3. Action of...

This activity introduces children to the Kodu games programming environment through tinkering. They are asked to experiment with an existing game code, and also to start from a blank screen.

Guided...

An ‘L’ shape is shown and the task is to find the centre of mass using only a straight edge and pencil. The solution makes use of the fact that the centre of mass of two objects will lie on a...

• Using tried and tested ‘Cloud’ based software that simulates the setting up of a racing car, students, working in small teams, complete a series of STEM relevant tasks in an effort to produce the perfect car. This ‘virtual’ car is then entered into a competitive race in the hope of...
