Summary

Each topic is designed for teaching over roughly 1-2 lessons.

This unit focuses on some of the numerical aspects of chemistry in terms of the ability to calculate amounts of products and reactants based on chemical reactions. It is a key skill that students must possess, in that it provides an extra layer of understanding and appreciation of chemical reactions. Each topic is presented so that new numerical ideas have an opportunity to settle into place before they are further developed and applied. There is ample time devoted to worked examples – giving students the chance to think and practice – with questions on each slide to deepen students’ understanding and learning. The unit brings to life a topic that many students find challenging, using meaningful and imaginative examples, that illustrate beautifully how chemistry can be interpreted quantitatively.

The complete series covers the AQA GCSE (9-1) Chemistry 8462 and combined science (Trilogy) 8464 specifications for Chemistry. Content relating to the separate Chemistry specification or Higher level material is indicated throughout for easy identification.

What people say...

“
”

I have found PG Online resources not only time saving, but also comprehensive – following the specification of the GCSE and A-Level courses that I teach. They are engaging for students and with the added bonus of homework’s and end of unit assessments planned out. The textbooks are also the perfect companion. I cannot recommend PG Online resources enough.

Lots of questions to gauge pupils understanding, great real life links with the slides, short pieces of info on each slide.
