A simple and effective practical demonstration of inertia using a spinning raw egg.

When the egg is spun its contents also spins.  Momentarily stopping the egg does not stop its contents from spinning.  On release the egg begins to spin again. The contents of the egg resist any change in its motion.

From the Integrating Mathematical Problem Solving project by Mathematics in Education and Industry (MEI), this activity shows how changing the price of a product changes the demand so putting the price up can reduce income. Modelling helps decision making. The mathematical ideas covered are:
• Percentage...

This video shows a simple method for making an electric motor using a battery, strong magnets and a copper coil. It allows students to investigate Fleming's left hand rule and the forces generated in an electric motor.

This STEMNET resource describes the background and career of electrical and electronics undergraduate, and STEM Ambassador, Caron Malone.

Caron had always been interested in electronics and studied physics, maths and technology at school. She gained a Power Academy scholarship, which was introduced by power...

This STEMNET resource describes the background and career of STEM Ambassador Peter Damer, an engineer working for General Electric.

Peter works in selling and installing control systems. His engineering background has led him to take on a variety of roles that have included maintenance, project management...

A Catalyst article about what causes faults in electrical appliances and the wiring installations in homes, and why people receive electric shocks. How regulations can reduce the risk of electrical faults and electric shocks is also examined together with the use of fuses, fuse wire and modern RCDs (residual...

A Catalyst article about the UK's extremely reliable electricity supply system generated in power stations which burn gas or coal, or use nuclear fuel. The article looks at how this is achieved using high voltages and how the demands for power at different times of the day and year are met.

This article is...

A multiple choice quiz on electricity, sensing, waves and quantum physics.

Although it is written for OCR AS/A level physics (H156, H556, H157, H557) it can be edited to suit your scheme of work.

This booklet contains a range of suggested teaching activities and contexts for teaching about electricity at A level. Curriculum links include charge, electron drift, energy, power and resistance, circuit symbols, electromotive force (e.m.f.) and potential difference (p.d.), Ohm's law, resistivity, series and...

This resource from the Institute of Physics, describes how electrocardiagrams (ECGs) record the activity of the heart through electrodes placed on a patient's skin. The teacher's notes contain an introduction to ECGs and lesson notes for the associated PowerPoint file. A mark scheme for the worksheet is also...

This series of activities from NASA take a mathematical approach to looking at electromagnetic radiation. They are intended as supplementary problems for students looking for additional challenges in mathematics and physical science from age 11 to 19 years. The problems were created to be authentic glimpses of...

Produced by StoryCog, this video demonstrates the process of electromagnetic induction. The video shows a simple piece of equipment that can readily be made which contains spinning magnets, a wire coil and a lamp. Spinning the magnets past the coil produces an electric current and lights the lamp.
