This Catalyst article looks at diamond and graphite which are allotropes of carbon. Their properties which depend on the bonding between the carbon atoms are also examined.

This article is from Catalyst: Secondary Science Review 2016, Volume 27, Issue 2.

A Catalyst article looking at what matter is made of. Snooker balls, plum puddings and solar systems have all featured in descriptive models of atoms. The article explores how people’s ideas about atomic structure have changed over the years by using specific examples of scientific study.

To understand how everyday devices like mobile phones, routers and satellites work, we need to understand what radio waves are and how we can transmit information with them. Radio communication is one of the key elements in our CanSat. All the data needed for our scientific experiment will be sent from the CanSat...

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

• Distinguish a chemical from a physical property.
• Use observations to identify substances with similar chemical properties.
• Sequence elements in the Periodic Table...

Teachers’ Guide I and Students’ Book I of Revised Nuffield Advanced Chemistry covered the eleven topics which constituted the work suggested for the first year of the course.

These downloadable videos and animations are part of the multimedia package Stuff and Substance, and are intended to be used to establish the concept of a substance. The individual video and animation files are provided separately here to allow flexibility in their use. The...

This Nuffield Advanced Physics Unit explored the topic of electricity and matter. It sought to develop basic ideas about current, potential difference, and charge, and to show some of the electrical properties of materials. These ideas were then used to understand...

This task involves investigating various aspects of interest and depreciation, including compound interest and the effects of calculating  compound interest over different periods of time (e.g. monthly vs. weekly). The task requires...

This resource contains exercises requiring students to answer questions relating to the dimensions of the square, the circle, sectors of circles, the cube, the cylinder and the sphere. The resource begins with teacher notes to provide some additional background information.

Squares: Students...

This collection of resources from the National Strategies includes resources for activities and lessons that make effective use of ICT in teaching and learning secondary mathematics. The resources include the use of spreadsheets, programs, dynamic geometry software, graph plotting software, video and internet...

In this activity, students take the role of data analysts of the World Water Resources Board (WWRB) a fictional organisation charged with providing financial aid to countries most in need of water. They will compare the availability of water in Algeria, Jordan and Turkey. Students will determine how to fairly...

These activities from the BEST project can be used with primary pupils. The diagnostic question probes pupils' understanding of the different elements of a sound. The response activity helps to develop pupils' understanding of how the size and frequency of vibrations affect the volume and pitch of sounds and is...

In this session you will look at how images are made on computers using picture elements or, more commonly known as, pixels. If you have access to a computer you can follow the computer based activity. If you do not then you can follow the unplugged activity. Either way you will begin a journey into understanding...
