Jamie JohnsonHost: Jamie (BSc (Hons), MSc, PGCE) is a Science teacher who is passionate about breaking down complex topics into digestible bites for students.

Half Life considers the how the radioactivity of a substances changes over time. 

In this class, students will cover the idea of the half life of a radioactive isotope, including what it means and methods to calculate it, both from a graph and mathematically. Students will then consider the half life of an isotope in relation to its particular uses and implications for storage and safety.

This is a difficult subject for many in Physics and this class provides a step by step description of the topic allow students to gain a full understanding and be able to apply their learning to assessments in the future.
