Jessica Klein Deters Host: Jessica is currently the Head of Science at a secondary school in Somerset. Previously she was both the Head of Science and Head of Sixth Form at a school in Greater London. Jessica has a total of 7 years teaching experience in schools from KS3 to KS5; AQA Combined Science, AQA Separate Science, OCR, IBMYP and IB Diploma.

In this class we are going to focus on more Calculations in Chemistry. 


Students will be introduced to isotopes and learn how to calculate the relative atomic mass from isotopes.  They will get the opportunity to practise some GCSE past paper questions as calculating relative atomic mass is a topic that appears frequently in examinations therefore it is vital to practise these questions to excel. 


Applying knowledge students have just learned to past questions allows them to make sure they have a good understanding of the topic and feel confident and ready for any exam or teacher assessments.
