This Salters’ Chemistry Course unit from the University of York Science Education Group covered:
* The range of properties of chemicals.
* The use of symbols, formulas and balanced equations.
* The commercial importance of chemicals.
* Factors...

The opposite corners of a trapezium are joined, creating four triangles within the trapezium. The areas of the triangles formed using the parallel sides as is given. The task is to calculate the...

A Catalyst article about increased levels of carbon dioxide causing global warming. The atmosphere is being polluted when fossil fuels such as petrol are burnt releasing carbon dioxide. Despite concern about global warming, it seems nobody wants to use their cars less. The article looks at what can be done to...

This interactive excel program covers distance/time and velocity/time graphs.

The first interactive sheet shows a distance/time graph made of line segments and some questions relating to speed for each segment and the...

In this challenge students are asked to produce a 10 minute presentation proposing sustainable travel plans for the journey from their school or home to two different event venues. One venue should be within the Greater London area and the other in any UK location.

Teams must show clearly how they arrived at...

This resource, from the Microbiology Society, gives an overview of the microbes that cause traveller’s diarrhoea (TD), how the infection is transmitted, how it is treated and how it can be prevented. TD is the most common illness that affects international travellers and each year 20–60% of globetrotters, an...

The first two interactive sheets deal with selecting objects from two bags. The outcomes are shown on tree diagrams and the probabilities can be revealed.

The next interactive sheet deals with the problem of passing...

A Catalyst article about wood as a renewable source of energy. Wood and biomass products could be used to generate electricity in the UK, and the article looks at the advantages and disadvantages of doing this and the technologies such energy generation would require.

This article is from Catalyst: GCSE...

In this resource from the Construction Youth Trust, students are asked to create loci and constructions when working with trees on a construction project. The materials have been written to help a non-teaching STEM professional to work with students in an educational setting.

The resources comes with a...

This resource contains three instant maths ideas requiring students to solve a quadratic equation, discuss what is meant by a degree of accuracy and explore discontinuous curves. The resource materials include an explanation of Cardano’s method of solving a cubic of the form x³ +mx =n and using the...

A triangle is split into two parts by drawing a line from one side to the base of the triangle. The ratio in which the sides are split is shown for each of the sides connected by the line. The task is to find what multiple of the smaller triangle is the larger triangle.

The ‘something in common’ between each...

A circle is drawn that is tangent to the three sides of the triangle. The two constituent lengths of the hypotenuse are given and the challenge is to calculate the area of the triangle. When...

This activity is based upon a practical task to fit a set of similar triangles into a spiral. It is in two parts, the first of which is more accessible.

In Part 1 students are presented with a series of different sized similar triangles. These fit together to form a spiral and students look at how many are...
