In this video, we start looking at waves. We explore the key differences between transverse and longitudinal waves. We then look at how when a wave travels, the wave moves but not the medium.

In this video, we look at static electricity. We start by looking at how electrons can be transferred from one insulator to another to create a static charge. We then look at how this is applied in a Van de Graaff generator. Finally, we explore how static electricity can be dangerous and how we can prevent this.

In this video, we look at nuclear fission and nuclear fusion. First we explore how nuclear fission works and what is meant by a chain reaction. We then look at examples of controlled and uncontrolled nuclear fission. Finally, we explore what is meant by nuclear fusion.
