The power point forms the lesson presentation and includes links to the youtube videos that the video worksheets are designed to be completed with and answers are included on the following slides.

The lesson would be well accompanied by a set of questions from your school’s textbook or an exam question from a past paper.

Structure of the lesson:
-Starter recapping atomic structure (also a suggested homework)
-Content on the structure of the atom - relative sizes of nulceus and atom
-Recap activity (video worksheet) on isotopes

• Introduction to nuclear decay and why it happens
• Video worksheet activity
• Introduction to the three main types of nuclear radiation (to be discussed in more detail in a following lesson)
