Worksheet with answers on reactions of carboxylic acids and alcohols to produce esters. Used as part of AQA GCSE Chemistry Organic Chemistry topic.

This activity includes an information sheet which shows students how to complete dot-cross diagrams, and lots of examples to practice with. Answers in a separate file.

Worksheet designed for AQA GCSE Chemistry Chemical Analysis topic, covering: Positive ions - flame tests, flame emission spectrophotometry and line spectra, metal hydroxide precipitates. Negative ions - carbonates, sulfates and halides. Summary combining positive and negative ion tests.

Worksheet with scaled practice identifying species and writing ionic equations.

(No answers) Summary sheet on separating and purifying substances. This was created for the Edexcel 9-1 GCSE but could be adapted for other specifications.

2 differentiated worksheets where students work out the displayed and molecular formula of the first 8 alkanes. Second more difficult sheet also includes working out the empirical formula.

Practice questions for the AQA Chemistry calculations topic (relative formula mass, relative atomic mass, moles, reacting masses and limiting reactants)

A worksheet (with answers) I made to give my Y7 class at the end of their Elements topic. Would also work well with AQA( Kerboodle) Activate 1 Matter 1 topic. Includes elements (their names and symbols), elements/compounds/mixtures, pure/impure substances & heating/cooling curves, dissolving/solubility, filtration & distillation, naming compounds & chemical formulae.

Made for AQA Activate 2 - Organisms part 2 (breathing and digestion).

This worksheet helps students practice the calculations needed for titrations, with scaffolding that is gradually removed. An answer sheet is included.

Worksheet for practising drawing displayed formulae of alkenes and their reaction products (including hydration producing alkanes, halogenation producing haloalkanes, and water producing alcohols). Used for AQA GCSE Separate Chemistry, Organic Chemistry topic.

Activity on predatory-prey cycles. Students can be given either the scaffolded worksheet or just the graph for them to describe and explain independently. Includes a food web/producers and consumers recap starter. Used with Activate 1 Interdependence and Plant Reproduction with a Y7 group.

Worksheet on halogen displacement reactions and their colour changes.

2 worksheet versions, one includes drawing the scientific diagrams for each piece of equipment while the other is just naming and describing functions. Answers included.

Worksheet for practising drawing displayed formulae of alcohols and their reactions products, e.g. reactions with oxidising agents and sodium. Used for AQA Separate Chemistry, Organic Chemistry topic.
