This presentation spans a series of lessons (2-3) covering the expressions of Ka and Kb and their magnitude. Slides contain modeled answers and questions for students to try, along with answer slides.

This presentation and student practical sheet looks through qualities of indicators and factors considered when selecting an appropriate indicator. The student practical sheet gets students to make ammonium sulphate using titration and methyl orange and also includes past questions with mark scheme.

This lesson pack introduces students to buffers, including an example in the body, plus calculation worksheet (with mark scheme) and student practical sheet to make their own buffer solution (recapping basic stoichiometry and making stock solutions) as well as comparing final pH of buffer using pH meter.

This lesson pack would be suitable over a 2-3 series and guides students through the preparation of Epsom salt (magnesium sulphate) and analysis to determine its water of crystallisation. This pack includes presentation, student practical sheet plus practical assessment paper with mark scheme included.

This presentation and student practical sheet guide students through the technique of preparing a stock solution of NaOH for titration against a primary standard (KHP).

This presentation and student practical sheet introduces the Arrhenius Equation and how it can be modified to determine activation energy (Ea) for a simple experiment using UV beads. The advantage of this task is it is far more straightforward for students to complete compared to more complex class practicals such as the reaction between bromate and bromide ions or the iodine clock reaction. There is also much less prep and tidying! This activity includes a spreadsheet of sample data and calculation which can be shared with students.

All empirical formula resources which cover: How to calculate empirical formula from mass or percentage composition How to calculate empirical formula from experimental data and associated sources of error and calculating uncertainty Water of crystallisation - preparing and analysing magnesium sulphate (includes a 20 mark formative assessment with mark scheme).

This complete workbook for structure 1 provides a comprehensive blend of class tasks, practical experiments, and exam-style questions to reinforce learning and ensure thorough preparation for assessments. The workbook includes key content aligned with the IB Chemistry syllabus, ensuring that students can build a strong foundation in this unit.

Presentation aimed as a starting lesson for introducing acid-base theory for KS4 or KS5. The lesson defines acids, bases and alkalis and includes a student task to develop a timeline on changes in acid-base theory from selected literature.

This 14 page guide provides students with a clear framework and instruction to structure their internal assessment (IA) for chemistry (first assessment 2025). It includes guidance on writing a descriptive RQ, how to format their report and how to process their data and report uncertainties.
