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...

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 Nuffield Working with Science unit was designed to help students to understand the need to consume less domestic heating fuel, to know the main ways in which heat can be lost from buildings, to find by experiment which substances make good insulators and to write a...

In this podcast from the Natural Environment Research Council's (NERC) Planet Earth Online collection, Sue Nelson reports from the Royal Botanic Gardens, Kew where she finds out that some plants like the Snake's Head Fritillary have enormous amounts of DNA in their genomes.

These plants struggle in extreme...

This set of inquiry-based teaching resources, created by the Royal Botanic Gardens, Kew, help teachers deliver inspiring lessons about plant science and the environment. These are a sample of a larger collection that are part of Endeavour, an extensive set of curriculum...

A presentation highlighting seven strategies for behaviour management.

This video discusses the use of video to learn science.  It shows that to be most effective a misconception is introduced at the beginning. The more mental effort used the greater the effectiveness.

A Catalyst article discussing how the human body has to handle all sorts of variations, balancing its inputs and outputs, if it is to work efficiently. The article concentrates on one organ, the kidney, and the way it helps to keep things on an even keel through the functions of homeostasis and excretion. What...

This Catalyst article looks at kidneys and how they are vital organs so it is important to understand how genetic disorders may affect kidneys and develop treatments to overcome them.

This booklet contains a range of suggested teaching activities and contexts for teaching about kinematics and dynamics at A level. Curriculum links include force, motion, kinematics, dynamics, speed, velocity, acceleration, displacement, suvat, free fall, projectile, trajectory, F=ma, free body diagram, drag,...

This video explains that moving objects have kinetic energy (E_k) and shows how E_k is proportional to both the mass and velocity of an object.

By combining the formulae F=ma and W=Fs to obtain W=mas and using v²=u² + 2as (assuming u²=0), E_k=...
