This resource supports the work on moments and turning effects.

An introductory experiment showing that electromagnets can conveniently be switched on and off.

The point of these questions is to stimulate curiosity and to demonstrate that waves have some interesting properties. At an introductory stage you must leave many questions unanswered.

A simple investigation of the factors affecting the resistance of a wire.

In this demonstration, students can get an overview of different types of radiation and can label them as alpha, beta and gamma. They can also see that there are different ways of detecting the different types of radiation.

A lesson focussing on Newtons Third Law of Motion.

<p>In this episode it is useful to extend the principle of Conservation of Energy to its wider context in order to give the students a full appreciation of the overarching nature of the principle when they meet it in different guises.</p> <p>Browse more conservation of energy resources <a href="https://spark.iop.org/search?query=&amp;f%5B0%5D=search__search__ontology_node%3A282" target="_blank" rel="nofollow">on IOPSpark</a>.</p>

This lesson demonstrates stationary or standing waves.

Students will be surprised how simple it is to make a loudspeaker, and are likely to remember their need for permanent magnets.

This lesson looks the processes by which the different types of radiation are emitted.

The common electromagnetic machines are motors, generators and transformers. All three are described in this episode but you will need to check your specification to find out which you need to cover and in what detail.

The final point in this topic is to return to the original definition of internal energy as being both kinetic and potential.

This episode establishes the ideal gas law, and how to use it.

This lesson demonstrates the effects of diffraction.

This lesson considers energy sources and resources, both renewable and non-renewable. There are many different ways to harness energy for human use. Though in the end, nearly all types of energy can be traced back to the sun and other stars

This episode continues to look at basic kinematics and introduces the equations of motion for uniform acceleration. This involves a little calculation practice. Uniform acceleration is compared with non-uniform acceleration.

Experiments to show that current (and therefore charge) is conserved around a circuit. They can be teacher demonstrations or student revision experiments.

<p>Energy must be supplied (or rejected) to increase (or decrease) the temperature of a material. Here is how to calculate how much.</p> <p>For more resources on specific heat capacity, head to <a href="https://spark.iop.org/search?query=specific%20heat%20capacity" target="_blank" rel="nofollow">IOPSpark</a>.</p>
