Published in 2016.  Mathematics anxiety (MA) is the state of discomfort around the performance of mathematical tasks. Does MA cause poor performance in mathematics, or is it poor performance in mathematics that causes MA? The question is important, because it affects the “treatment” that results. Should the focus...

This video demonstrates how applying pressure to ice melts it, yet on removal of the pressure the ice re-freezes.  This is called regelation.

This article, from the Association of Teachers of Mathematics (ATM) publication ‘Mathematics Teaching’, is written by Pete Griffin and taken from MT227.

The notion of ‘understanding’ and its place in the learning process is often placed in sharper focus when considered in the context of learning and teaching...

A Catalyst article about Dorothy Hodgkin who was a pioneering scientist, a peace activist, a mother of three and a Nobel Prize winner. The article looks at her life and work in science. She did valuable work as an X-ray crystallographer and in finding the structure of biologically important molecules such as...

Like the Deflection tube investigation this allows A-level students to measure the specific charge for an electron. It provides a step-by-step guide, along with the calculations that are required to find this measurement.

A series of images representing double helix images.

• DNA double helix and sequencing output: molecular model of a DNA double helix showing the individual atoms (apart from hydrogen) as coloured balls. Carbon atoms are in white, oxygen in red, phosporus in purple and nitrogen in blue....

This kit and their associated resources are designed to help teach about double-slit and diffraction patterns.

Before teaching this, students should:

• be familiar with constructive and destructive interference;
• be aware that we get diffraction when a wave travels through a gap;
• ...

Produced by Science & Plants for Schools (SAPS), the investigations suggested in this resource use duckweeds. These seem to be simple plants - small, green, and with no flowers. However, this simplicity makes them ideal experimental organisms for investigations into...

A Catalyst article about Charles Darwin's home and in particular his study which is open to the public. Visiting information is included in the article which puts into context the importance of this room in his work.

This Catalyst article looks at how people lived in the past, archaeologists look at the items (artefacts) these cultures left behind. Using chemical analysis of residues in the artefacts an enormous amount of additional information can be gleaned. This article investigates early dairy farming. Analysis of tiny...

From the Microbiology Society, this resource contains information about biofilms. These are communities of microbial cells attached to a surface. For example, the slime lining plugholes and drains or the rough deposit that can coat teeth at the end of the day. The information clearly describes: * What are biofilms...

Computer modellers use computers to help them understand how the world works and to help predict what might happen in the future. Sea ice modellers use computer software to simulate how ice freezes, melts and moves and how different things such as ocean temperature affect it. A Levels: Maths, Further Maths, Biology...

A Catalyst article about the working life of Dr Gillian Lockwood, a reproductive biologist who specialises in IVF. The article looks at the ethical issues surrounding fertility treatments for problems such as polycystic ovary syndrome.
