This worksheet looks at electrolysis, its use in the extraction of sodium and aluminum and in the purification of copper. Having completed it, students are then asked to set up a simple electrolytic cell to obtain pure copper and calculate and measure the amount of product deposited at an electrode during...

Climate change has increased heat waves and drought on land, and doubled the probability of marine heatwaves around most of Africa. This resource contains a PowerPoint presentation, a graphing skills activity drawing and interpreting line graphs and a spreadsheet containing data. This is a good source of material...

This Catalyst article looks at life in extreme environments on Earth which can suggest how life might exist on Mars. One of the developments in recent years that really opened up scientists’ eyes to the possibility of life on Mars has been the realization of just how adaptable and versatile life on Earth is.

A Catalyst article examining the basic functioning of the eye and what can be done to maintain function when something goes wrong. In particular, the article looks at problems with focus, cataracts and colour blindness and how these problems can be detected and treated.

This activity is produced by the Maths Magic project. F=ma in a Helicopter provides examples and ideas for A-level mathematics and physics students investigating what happens to packages hanging below a helicopter. The lesson plan describes an active lesson designed to promote discussion about what happens when the...

This activity is produced by the Maths Magic project. F=ma in a Lift provides examples and ideas for A-level mathematics and physics students investigating what happens when they are being weighed in a lift and to have a discussion about mass and weight and the difference between the two quantities. Ideally...

Scientists at the University of Oxford are investigating the link between sporting activity in young people and the development of osteoarthritis. In very active people, bony lesions can form on the hip joint which increases their risk of developing the condition.

This Catalyst article describes how human faces contain a wealth of information about the individual - so how do we go about interpreting faces?

This article is from Catalyst: Secondary Science Review 2016, Volume 26, Issue 4.

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

These fact sheets, from the National Physical Laboratory, are ideal posters for the classroom. They include illustrations and images to accompany the text. The following curriculum areas are covered: 

• Acoustics: sound, frequency and ultrasound
• Einstein: relativity, mass energy relation and...

This article explores...

This Catalyst article investigates how scientists make images using colours to represent electromagnetic radiations which humans cannot see. Human eyes detect visible light, just a small region in the electromagnetic spectrum. Using scientific instruments, many other types of radiation can be detected. Different...

A Catalyst article about encountering the fossils of the bones or shells of individual animals embedded in sedimentary rocks. This article looks at some extraordinary fossils of plants and animals preserved together in an ecosystem - it is even possible to see the cells of which they were made. The article also...
