In this resource from Shirley Fall, students are presented with a general straight line y=mx+c and are shown that the gradient of the line between any two points that lie on the line is always equal to m. Students should be encouraged to explain the proof to check...

This activity, from Shirley Fall, requires students to use and interpret function notation, sketch graphs using key points, explore the common transformations of translate parallel to the y axis, translate parallel to the x axis, stretch parallel to the y axis from the...

A collection of various resources, from the Association for Science Education (ASE), set in the context of sea, the moon and chemistry of the oceans. The resources are part of the SYCD: Science Year Is There Life? collection.

'All at sea? The chemistry of the oceans' is a very attractive ten-page booklet...

This Catalyst article takes the form of a practical activity. Many breakfast cereals are fortified with iron and it is possible to extract this from the cereal by following the instructions in the article.

This article is from Catalyst: Secondary Science Review 2008, Volume 19, Issue 2.

In the 1970s astronomers took an image of a region of the surface of Mars called “Cydonia“ which resembled a face.   ...

This resource contains two interactive excel programs which enable students to investigate cubic functions and the relationship between the factorised form and the graph.

This question asks us to consider a person opening a burger bar, doing all of the cooking themselves, and then estimate how much space should they rent?

The main topics required are rates (number of burgers per hour that one person could cook, number of customers per hour), and areas. 

This resource presents some real seismic data recorded before a volcanic eruption and allows students to locate some of the resulting earthquakes by use of graphs and maps.

This resource, produced by SEPNet and Queen Mary University of London, uses Lego to represent the building blocks of matter. Different colour and size Lego bricks are assigned to protons, neutrons and electrons. Fusion is shown by joining bricks together and fission by breaking large collections of bricks apart....

This challenge, from Practical Action, requires students to design and build a model structure that will enable farmers to grow crops even in an area that may become flooded. A floating garden, built on a base of aquatic weeds, is a low cost and sustainable way of allowing people to grow vegetables. The resource...

The network flow problem involves finding the optimum route through a flow network; a directed graph where each arc has a capacity and each arc receives a flow. Typical examples include: evacuation plans and delivery services. The problem involves students analysing the plan of a school canteen and deciding whether...

These resources cover themes of food sustainability and security. Included are technical briefs which focus on low cost approaches related to food production and preservation. Technical briefs are documents produced by Practical Action which are freely...

What is the perfect curve of a ball’s trajectory, what must the ideal turf be like, and...

This excel file contains a series of sheets which give practice in rearranging formulae and substituting values. Clicking on the subject of the formula reveals the rearranged form. The answers to the calculations are also available.

Mathcentre provide these resources which cover aspects of functions and graphs. They include explanations of linear functions, the exponential constant, the graph of a function and linear relationships.

Comprehensive notes, with clear descriptions, for each resource are provided, together with relevant...
