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

• Describe how energy can be transferred from one store to another.           
• Describe how the amount of energy in each store changes as energy is transferred.
• Explain why...

From the Institute of Physics, this learning episode looks at the resistance of a metal and a semiconductor, giving a microscopic explanation of how resistance can vary with temperature. There is also a brief look at superconductivity and its applications.

In these activities, from the Institute of Physics, the concept of electrical power is explored. Students find that the energy transferred by an electrical component depends on the potential difference, current and the time for which it operates.

In this learning episode, from the Institute of Physics, students discuss, examine and enhance their understanding of scalars and vectors. For some students this will be a revision session whilst others may be less familiar with the concepts. The topics examined include: * defining scalar and vector quantities *...

Produced by the Institute of Physics, these discussions and demonstrations show that in a generator, motion of a conductor in a magnetic field induces an electromotive force (emf). In a transformer, it is the changing field that induces an emf in a fixed conductor.

The activities in this learning episode...

Produced by Science & Plants for Schools (SAPS), this investigation looks at the effects of ethene of fruit ripening.

Ethene is a colourless gas and is produced by plants, acting as a plant growth substance. Its...

Written in 1999, and published by the Biotechnology and Biological Sciences Research Council (BBSRC), this book looks at issues surrounding the ethical use of animals in the field of biotechnology.

The chapters in the...

Written in 1996, and published by the Biotechnology and Biological Sciences Research Council (BBSRC), this book looks at issues surrounding the use of genetic modification in agriculture.

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

• Use a light microscope to make and record observations of a variety of cell types.
• Describe the common structures of eukaryotic cells and the functions of these structures.

This book from the SISCON series starts with Darwin's ideas about natural selection; including the religious and scientific reactions. It then discusses some of the achievements and problems of genetics up to the 1980s.

The objectives of this activity are to expose common misconceptions about the nature of forces and to introduce Newton’s Laws of Motion. Students are asked to place the headings, true, false, unsure at the top of their paper and place the accompanying cards into the appropriate column, giving reasons for placing it...

These PowerPoint presentations from MEI demonstrate a variety of methods which can be used to factorise polynomials. The techniques include factorising cubics and quartics by inspection; using a table and algebraic long division.

The activities in this collection link the study of textiles and materials with the science programmes of study. They show how textiles can be used in two very practical ways to reduce the danger of severe burns and in medical applications.

The activities are designed for key stage three students and help to...

These downloadable videos and animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to develop ideas relating to flames, from hydrogen to candle wax.
