# Matter and nuclear CPD videos

CPD for 11-14 14-16 16-19

In matter and nuclear physics, we explain macroscopic behaviours using descriptions of microscopic models. This presents challenges to student thinking; as teachers we have to work carefully to use the appropriate language to help students to build their understanding. These videos highlight this, student misconceptions and other suggestions for teachers.

#### 11-14

##### States and models

Peter and Helen explore models to explain the states of matter, addressing common misconceptions and language for the microscopic and macroscopic.

##### Radioactive decay 1: α, β, γ

Ben and Sue discuss the difference between irradiation and contamination, show how to model α, β, γ decay and demonstrate the spontaneous and random nature of decay.

##### Radioactive decay 2: half-life

In part 2 of the radioactive decay videos, Ben showcases a wide range of kit to model and measure half-life; he discusses how to help your students interpret decay graphs, and he describes uses of isotopes.

#### 16-19

##### Nuclear particle physics

Nuclear particle physics is an exciting, new topic for your advanced students. Gary and Nicky present an array of effective teaching approaches for this topic, including: the standard model; the scale and structure of the nucleus; quarks; the strong force; antimatter and mesons.
