This video discusses the concerns people have about radioactivity and shows that, rather than the radioactivity itself, it is the radioactive atoms that are of greater concern.  Radioactivity (alpha and beta particles) is relatively harmless unless it enters the body.

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

• Explain that the properties of a compound may not be inferred from the properties of elements made up of its constituent atoms.

• Use particle diagrams to represent the...

This is one of the six Background Books published for Stage I of the Nuffield Chemistry Sample Scheme. The books were highly illustrated and designed to be attractive. This book describes aspects of the history of chemistry by exploring the discovery of the elements...

This lesson develops the concept of calculating the volume of compound objects. In particular, students enhance their understanding of:

• Computing measurements using formulas.
• Decomposing compound shapes into simpler ones.
• Using right triangles and their properties to solve real-world...

This video explains how atoms are the fundamental building blocks of all matter and that they are made from sub-atomic particles (proton, neutron and electron). The simple structure of a hydrogen atom is made from plasticine. The video explains how adding a neutron to the hydrogen atom does not change its...

This activity uses Rutherford’s gold foil experiment to show how a scientist carried out an experiment to test a theory and how the unexpected results led to the proposal of a new one.  Students carry out a process of observe, hypothesise, test and conclude in order to work out what a mystery object is.

This resource contains 13 instant maths ideas designed to provide the opportunity for students to explore the notation of time and the decimalisation of time, work with bus and train timetables, discover what speed an aircraft flies when it travels at ‘mach 2.5’, what crafts’ speed is measured in knots, calculate...

Keys to Chemistry Book 2 continued from Book 1 and took the study of chemistry in secondary school up to thw now discontinued 'O' level standard. The book is a reflection of chemistry teaching in the 1970s, following the Nuffield developments in the previous decade.

1. Particles in motion...

This simulation allows you to build an atom out of protons, neutrons, and electrons, and see how the element, charge, and mass change. Students can then play a game to test their ideas.

Curriculum links include:

• Atoms
• Atomic Structure
• Isotope Symbols
• Atomic Nuclei...

This Nuffield Chemistry Data Book contains the following sections:

Section 1: Basic information
Table 1.1 Selected...

From the Institute of Physics, these resources are split into topics and each topic is subdivided into a number of learning episodes. Each episode represents a coherent section of teaching, that takes typically one or two lessons to complete.

The topics covered are:

* Quantum physics
* Lasers...

This Nuffield Advanced Physics Unit offered an introduction to quantum theory presented in a single volume for teachers and students. The main work was theoretical. Many of the arguments were presented as a chain of questions.

This article describes the processes behind discovering and proving the existence of new chemical elements.

This article is from Catalyst: Secondary Science Review 2016, Volume 26, Issue 3.

A multiple choice quiz on elements from the sea for AS/A level chemistry.

Although it is written for OCR AS/A level chemistry (Salters) H033/H433 course, it can be edited to suit your scheme of work.
