A Catalyst article about the hunt for an explanation of inheritance. The role of chromosomes was announced in 1903 and the structure of DNA was revealed in 1953, both of which were major scientific breakthroughs in this field of research. This article examines the history of inheritance.

A Catalyst article about careers in geological exploration. The article contains a case study about an exploration geologist and looks at an undergraduate degree course in exploration geology.

This article is from Catalyst: GCSE Science Review 2007, Volume 17, Issue 4.

This publication from the Department for Education lists ten tips on how to help young students make informed decisions about STEM courses and careers. A list of useful websites including information on STEM initiatives and careers is also provided.

This booklet, from Science Community Representing Education (SCORE), offers a range of practical activities for use in the classroom. Most are aimed at Key Stage Three and Four and Post-16 students but a small number are provided for Key Stage Two to highlight the...

The resource includes an adapted version of an ethical framework for dementia, and an accompanying set of scenarios to help people work through dilemmas that may arise in the context of dementia care. The worked example can be used as a starting point.

The resource consists of:

• Introduction...

Produced by the Citizen Science project, this teacher guidance summarises ideas on how to run successful discussions and debates within the secondary classroom. Examples illustrate how a range of techniques, such as TV chat show formats, can be used successfully.

These materials will help teachers to:...

These images, from NASA, show crafts that have been used in the surface exploration of Mars. They illustrate space exploration including the Mars Viking lander which looked for signs of life on Mars.

From the Institute of Physics, this pack of activities aims to encourage teachers to work together in providing a consistent approach to careers advice and guidance. It will also help teachers to build on their own knowledge of physics-based careers and, in turn, help...

A Catalyst article following the journey of the space probes Huygens and Cassini, sent to explore Titan, a moon of Saturn. After a seven year journey Huygens was set to fall through the atmosphere transmitting data back to Earth via Cassini so more can be learnt about this distant moon. The article describes the...

In this resource from the DfE Standards Unit, students explore trigonometrical graphs by recognising translations, stretches and reflections from their equations, sketching the graphs and learning about the period and amplitude. Students should be familiar with the graphs of y = sin x and y = cos x and have...

Published by the Wellcome Trust in September 2011, this report aimed to find a deeper understanding of young people’s attitudes to science education, particularly regarding the value young people place on science education (for themselves as individuals and for society in general), as well as the key factors...

This activity, from Shirley Fall, contains ten linked problems which are intended to lead to students developing a rule for integrating functions of the form y=ax n where n not equal to -1. Problem 1 begins by exploring the area enclosed under a straight line y=2x+3 from x=0 to x=a for varying values of a, leading...

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 Catalyst article describes discovering hydrothermal vents at ocean sea-beds. Hydrothermal vents form along mid-ocean ridges. A mid-ocean ridge is where the Earth’s tectonic plates are moving apart, usually at a rate of about 6 to 18 centimetres a year. The presence of hydrothermal vents had been predicted by...

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...
