Isotopes & atomic structure

A short introduction to isotopes, with a recap of atomic structure first.
Self and peer assessment opportunities. Worksheet with past paper questions and mark scheme included.

This is a short lesson I used to try and explicitly get my year 10 students to recall what isotopes are. This is something they always struggled with, and is a regular question in exams!
The lesson has a starter activity with a fun fact, followed be a recall activity where students recall atomic structure (this is split into bronze/silver/gold with success criteria). This is followed by model answers and a chance for self-assessment.
Then it leads into isotopes using carbon as an example.
The included worksheet can now be used to encourage recall for calculating atomic/mass number.
This is followed by definitions and then the second half of the worksheet, which has isotope related questions to put their knowledge into practice.
Finally an opportunity for peer-assessing the worksheet with the answers on the final lesson slide. Worksheet is at the end of the PPT.
