These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Describe the heating effect of current on a conducting wire.
• Predict changes to current through transmission lines using P = I x V. 
• Calculate power dissipated by a wire...

This issue of Catalyst includes the following articles:

Diving Deep

Many mammal species can dive to great depths. This article explores how their bodies are adapted to cope with the great pressures involved.

We know that in the current situation, STEM activities may be harder to run, especially with concerns about sharing equipment in groups.  We have selected over 50 activities that can be done in any classroom, with very little equipment.  These can...

We know that in the current situation, teaching is taking place in bubbles, where teachers and students will often not have access to laboratory spaces, or equipment.  We have selected over 50 activities that can be done in any classroom, with...

In this topic from the Association for Science Education, students study the life cycles of plants and the adaptation of plants to different environments. The topic allows classes in schools across the world to exchange information about plant cultivation. The topic also provides a context for studying plant...

The Nuffield Primary Science in-service pack was created to introduce teachers to the SPACE approach and its potential for the teaching and learning of science in primary schools. The pack follows the SPACE approach in content and style so that teachers can experience...

This topic, from the Association for Science Education, allows classes across the world to exchange information about waste management. Students discuss the ways in which their community deals with waste and what can be done to cope with the problems caused by waste.

This topic introduces students to the...

This topic, from the Association for Science Education, allows classes in schools across the world to explore and exchange information about the applications of photovoltaic devices. The version of the topic that can be downloaded here is a trial version and is provided only in English. This resource was edited by...

Purpose: As students progress through secondary science they will develop an understanding of waves as a means of transferring energy. Practical science activities around the study of sound are often used as a basis for understanding features of waves such as wavelength, frequency and amplitude. Digital technology...

This Catalyst article explores the processes undertaken during the construction of a white water canoe course for the Olympic Games which requires a huge range of practical skills, but also great science skills too. The scientist must calculate how much noise from both the course's construction and its use during...

A Catalyst article about the life and work of the physicist Robert Hooke. Hooke was a man of many interests. He invented many mechanical devices, including the universal joint used in all cars and designed a balance wheel for a watch. As part of his wide ranging observations, using a microscope, he first coined the...
