Produced by the Wellcome Trust Sanger Institute, in this activity students have to use their observational skills to identify and record the difference (phenotypic change) between two images, one wild type zebra fish and one mutant zebra fish.

To aid in their diagnosis of the phenotypic change, a glossary...

Botanic Gardens Conservation International (BGCI) resources look at the effects of climate change.This activity encourages students to make observations, record data and be aware of the links between weather and trees Students work with their peers to collect data using drawings or photographs. They also make notes...

A Catalyst article about careers in meteorology (weather forecasting) and climate science. The article explains the work of EMARC (Environment Monitoring and Response Centre) and provides some advice on training as a meteorologist.

This article is from Catalyst: GCSE Science Review 2004, Volume 15, Issue 2...

Published in Electronics Education, this article is aimed at giving guidance to teachers and explains the ideas and models behind the understanding of electric current.

The article begins by discussing the make-up of...

This video shows how electromagnetism can be explained using either models of magnetism or of electric fields, induced by length contraction caused by special relativity. Length contraction (Lorentz contraction) occurs to anything that is moving – relative to something moving...

In this activity students consider the questions: How does heat energy move around? How can we model the flow of energy and changes in temperature? What can be done to prevent hypothermia? Why do we need to try so hard to stay at the right temperature? In order to survive and be comfortable in hot or cold...

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

• State that the energy in the gravitational store depends only on the mass of an object and its position in the gravitational field.         
• Describe how gravitational field...

With a population of over eight million and many people commuting to London for work every day, transport is a key issue for everyone.   Modern technology has developed to cope with the movement of such large numbers of people. However the reliance on combustion for transport over time has resulted in problems of...

This Handbook for Teachers was one of the first publications of the Nuffield Science Teaching Project and explains the theoretical rationale underlying the Chemistry Sample Scheme. The analysis set out in the Handbook led to developments that are still reflected in...

These resources from the Wellcome Trust look at how populations grow, change and move, and why understanding them is so important. The resources use real research to illustrate many aspects of the study of populations, including:

• ecology
• epidemiology
• ...

This video explains how zero point energy in helium-3 and helium-4 atoms means that atoms, even at absolute zero vibrate. The smaller size of the helium-3 means it vibrates more.  In a mixture of helium-3 and helium-4 the helium-3 atoms can get closer to helium-4 than to other helium-3 (less vibration in helium-4...

This resource, from the Royal Observatory Greenwich, introduces students to how our understanding of gravity has changed over time, and what this means for the gravitational field strength of different bodies in our galaxy.

...

This resource is designed to help students understand:

• Different averages: the mean and the median.

• Measures of spread: the standard deviation and the interquartile range.

• Statistical diagrams: histograms and boxplots.

Self teaching notes and questions are contained on the work...
