Students will: Define the term half-life Make calculations involving numbers of half-lives Relate half-life to decay...

Lesson 16-19

This episode assumes that students already have an idea of half-life, and links it to the empirical decay curve.

Lesson 16-19

Here, the key idea is the random nature of the decay. Avoid simply pulling pull equations out of the air – at least make them...

Lesson 16-19

Students may find this mathematical section difficult. It is worth pointing out that they have already covered the basic ideas...

Lesson 16-19

In this episode, students look in detail at Rutherford’s experiment and relate it to a mechanical analogue.

Lesson 16-19

Having established the existence of the nucleus, you can now consider experimental evidence for its size, starting from the...

Lesson 16-19

This episode introduces an important phenomenon: wave – particle duality. In studying the photoelectric effect, students have...

Lesson 16-19

You could extend the idea of electrons-as-waves further, to the realm of the atom.

Lesson 16-19

Most schools will not have an X-ray set, but there are plenty of effective analogue demonstrations using other types of waves...

Lesson 16-19

This episode takes a very brief look at the topic of neutron diffraction.

Lesson 16-19

It is helpful to start this topic by discussing capacitors, rather than the more abstract notion of capacitance .

Lesson 16-19

Having established that there is charge on each capacitor plate, the next stage is to establish the relationship between...
