OCR Physics decay equation and half-lives

This is a complete lesson covering sections 6.4.1 d, e, f, g and h of the OCR Physics specification- the decay equation and half-life. It starts by introducing the decay equation with worked examples before outlining how dice simulation can be used to model nuclear decay. The lesson then moves to looking at activity as an alternative expression for the decay equation. Half-lives are then covered including how to calculate it and how to work it out form a graph. The lesson closes by looking at how age can be assessed using C-14 dating.

The lesson includes a starter, full notes, various student led activities and a differentiated summary at the end.

All answers are included.

I actively try to reduce photocopying, so all of the lesson resources are within the PowerPoint rather than as extra sheets.
