A Catalyst article about Earth’s biodiversity much of which appears to be teetering on the brink of a man-made extinction crisis. Scientists have suggested that, unless urgent action is taken now, many species will disappear in the next 50 years. This article looks at some of the issues involved.

Produced by the Royal Astronomical Society, this booklet examines the possibility of extraterrestrial life in the Universe. Many astronomers believe that there is life out there, but where is it? Is there life comparatively nearby, in our Solar System, or do we have to look to planets beyond the solar system that...

This resource from NASA describes how low-mass stars expand in size and become red giants at the end of their lives. Then they shed their outer layers and become planetary nebulae.

The image of NGC 2440, a planetary nebula, is on the first page of the lithograph. Background information about the life cycle...

This resource, from the European Space Agency, contains exercises in physics and chemistry based on real space data, designed for secondary schools. The exercises and data were developed and checked by ESA space scientists and engineers. They are most appropriate for students at Post 16 level. There are a total of...

Light is one of the titles in the series of ASE Lab Books that were published in the early 1970s for the Association for Science Education by John Murray. Each title covered one or two topics and brought together the best of the teaching notes and experimental ideas...

The best school environments give an impression of liveliness, with attractive spaces and a general feeling of pleasantness which it is difficult to define. There can be no doubt that in these cases the surroundings contribute to the happiness and well-being of teachers and pupils, and that lighting plays a...

Since 1951, Nobel Laureates and young scientists have met in Lindau in Bavaria for a scientific conference which aims to foster scientific exchange between different cultures and generations.

These animated videos use clips from some of the conference presentations to explain globally relevant scientific...

This resource, from Susan Wall, contains a number of advanced level activities designed to practise and strengthen understanding of linear functions. Although students have worked with linear functions at GCSE connections between properties, equations and diagrams are not always secure. At advanced level students...

Linear Programming involves creating a function that represents a real life problem. The aim is to optimise this function given certain constraints. Simple examples of linear programming will have few variables and constraints, however, real life situations will have many more variables and constraints that will...

This resource is part of a collection of Nuffield Maths resources that explore Algebra and Maths. The demand is roughly equivalent to that in Higher Level GCSE and Level 2 Functional Mathematics.

The resource is an introduction to linear graphs, leading to the link between the constants in the standard form...

In this DfE Standards Unit resource, students identify different forms and properties
of quadratic functions, connect quadratic functions...
