In this learning episode, from the Institute of Physics, students derive the equation relating electromotive force (emf), terminal potential difference, current and internal resistance. They then tackle questions about the internal resistance of a power supply.

In this learning episode from the Institute of Physics, students tackle practical work looking at the efficiency of a ramp to think of force as a mechanism by which energy is transferred from one body to another. The activities include: • discussing students' current understanding of force, gravity, energy and work...

This learning episode, from the Institute of Physics, uses demonstrations and worked examples to examine the forces involved in changing momentum. It introduces the concept of impulse.

The activities in the learning episode include:
* showing that impulse equals change in momentum
* a...

The Thames is a working river, providing transport, trade and of course water to London but also presenting significant engineering challenges, such as defence of the city from flooding. This unit covers the topics of pressure in liquids and gases and simple machines from the key stage 3 science curriculum and uses...

Produced by the Institute of Physics, this learning episode considers the forces acting on a falling body in air and moves on to related experimental work.

The activities include:
• demonstrating the motion of...

The simple pinball machine in this activity is made from a cardboard box, with ice lolly sticks as the flippers. It provides a great opportunity to explore the science of forces and motion. Game on!

Learning outcomes:

• Investigate simple mechanisms and Newton’s Laws of Motion
• Use...

In this topic, from the Institute of Physics, students learn to describe motion in terms of displacement, velocity, acceleration and time. There is only a limited discussion of the forces involved as kinematics is concerned with describing motion, while dynamics is concerned with explaining motion in terms of the...

The work suggested in this Nuffield Working with Science unit was planned so that students should:
1. be aware of the advantages of a systematic approach to car selection and purchase
2. be aware of the legal and social responsibilities of car ownership
3...

What do dental fillings, catalytic converters, mobile phones and jewellery have in common? They all make use of the metal palladium. This Catalyst article explains the properties of this metal, and how it can be used for a vast array of objects.

This set of four profiles of UK industries give an overview of each one and is designed for students to gain an insight into careers available to people who have studied STEM subjects. The industries featured are the nuclear power, pharmaceutical, renewable energy and maritime industry.

Each profile includes...

This IPSE publication from the Association for Science Education (ASE) presents findings from the evaluation of the Local Education Authorities (LEAs) taking part in the Government funded scheme for promoting science in primary schools, 1985-8. The different LEAs adopted a wide variety of strategies for developing...

National Science and Engineering Week (NSEW) is the UK’s widest mass celebration of all things science and engineering. Students from all departments across the Reading College showcase their work to portray scientific and engineering aspects. The week is full of events, participative activities, experiments and...

This resource shows how you can successfully lift a person off the ground using two cordless leaf blowers, problem-solving skills and some STEM knowledge: the same knowledge and skills that are used to design hovercraft.

Curriculum links include:

This video shows how a slinky, which is being held at the top with its bottom freely dangling, falls when released.

Students are asked to predict what happens when the slinky is released.  Does the top fall first? Does the bottom fall first? Do both ends fall together or does the centre of the slinky remain...
