Produced by the Royal Observatory Greenwich, this booklet uses the context of exoplanets and alien worlds to develop students understanding of speed, distance and time. Included is an online video that discusses where and how we might find alien worlds. Questions and answers are included that test a student’s...

Karsten works at the University of Leeds as a scientific researcher, in the School of Earth and Environment.  He uses images taken by satellites to look the movement of structures such as railways, roads and gas lines.  He also examines the movement of the Earth due to volcanic eruptions and earthquakes. ...

Purpose: It is good practice for science students to record information as they progress through an investigation. This information may include adjustments in the procedure followed, safety notes, rough data, processed results, links to relevant information and so on. There are a wide range of commercial lab book...

This Salters’ Chemistry Course unit from the University of York Science Education Group covered:
* The use of soaps and soapless detergents.
* Emulsions and the action of emulsifiers.
* The hardness of water.
* The manufacture and use of cosmetics,...

A Catalyst article about modern car engines and how they can run smoothly and propel drivers for thousands of miles without needing much attention, apart from refuelling with diesel or petrol. The engine also needs oil. The article describes engine oil, its composition and ingredients, how it works and how to...

This topic, from the Association for Science Education, is designed to allow classes in schools across the world to explore and exchange information about common diseases, their treatment and the importance of lifestyle in determining good health.

A Year Ten module from the Salters’ double award science course. Practical tests using “urine” samples illustrate chemical diagnostic testing for illness. Different types of illness are classified, also different types of micro-organisms and the body’s defences against them. Experiments show how bacteria grow and...

A Catalyst article about homeostasis describing how the process enables birds and mammals to be active on cold days when other species are not.

This article is from Catalyst: GCSE Science Review 2004, Volume 14, Issue 3.

This Mathematics Matters case study, from the Institute of Mathematics and its Applications, looks at how mathematics modelling can aid investigations into the circulatory system. Blood-related diseases can seriously harm patients’ quality of life and even lead to death. Many of these diseases are caused by...

This activity, from the Royal Observatory Greenwich, illustrates Kepler’s Third Law for our own Solar System using graphical methods, with a further look at how the same law can be used to derive information about the orbits of exoplanets around their parent stars....
