Key takeaways
Be able to describe radioactivity of a substance changes over time, recalling its unit.
Be able to define the term half life in two different ways.
Be able to explain and demonstrate how half life can be used to work out how much of a substance has decayed.
Host: 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 class is great for students in Years 10 and 11 who are struggling and need an extra push!
