Matter and nuclear CPD videos

CPD for 11-14 14-16 16-19 IOP RESOURCES

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.

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.


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.
