I am a GCSE and A-level Chemistry specialist teacher in a 14-18 school with 15 years teaching experience and several years research experience. I provide GCSE, AS and A2 Chemistry resources (mainly for the AQA specifications) to help students practice the concepts learned in lessons and I am a firm believer in 'Practice makes perfect'. I strive wherever possible to include the answers to the worksheets.

GCSE Chemistry Calculating Relative Molecular Masses (Mr) starter/plenary

(0)
This is a PowerPoint activity that can be used as either a starter or plenary to assess understanding of how to calculate Mr for different substances. Slide 2 could be printed onto cards and each student given a different card to work out the Mr (30 different substances in total). If the relevant substance is clicked on slide 2, the PowerPoint shows the correct Mr for that substance. This is a useful AfL tool.

AQA GCSE Chemistry Trilogy 5.1/5.4 Ionic Formulae, Salts, Acids and Alkalis Formulae Activity Cards

(0)
A set of four activity cards to help learn the basic ions and to revise and practise writing formulae for ionic compounds including salts, acids and alkalis. This covers some of the formulae writing and ions recall required for AQA GCSE Trilogy Science and GCSE Chemistry. These cards are formatted as labels and can be printed as sticky labels (4 labels per sheet, 99.1 x 139mm) for sticking directly onto cards or for sticking directly in student books.
GCSE Chemistry Structure and Bonding Questions (Sticky Labels)
hf583hf583

GCSE Chemistry Structure and Bonding Questions (Sticky Labels)

(0)
The four files listed contain 4 different questions to assess learning of the fundamentals of Structure and Bonding. They are set up to be printed on 21 labels per page sticky label sheets. These can be used in conjunction with diagnostic homework - for example, if students have incorrectly answered a question on ionic or covalent bonding, these can be used to supplement and reinforce any corrections to be made upon student feedback. Bonding 1 looks at basic bonding questions for ammonia and Bonding 2 does the same for lithium fluoride. Bonding 3 asks students to draw the electrons arrangements for the atom and then the ion formed, working out the charges the ions end up with. Bonding 4 requires students to explain and describe the type of bonding in different substances.
AQA AS and Year One Chemistry Key Words and Definition cards
hf583hf583

AQA AS and Year One Chemistry Key Words and Definition cards

(0)
Key words and definitions for AQA AS and Year One Chemistry. In the key words and definitions file, the key words and definitions are attached but could be easily separated to produce a sort card activity or used as is for general revision. The pairs memory file contains the same key words and definitions but are separated to use as a matching activity. Definitions include oxidising agent, reducing agent, oxidation, reduction, electrophile, nucleophile, standard enthalpy of combustion, standard enthalpy of formation, hydration, substitution reaction, structural isomers, stereoisomers, mean bond enthalpy, enthalpy change, Hess’s law, activation energy, electronegativity, hydrolysis, addition reaction and elimination reaction.
