A simple worksheet, with chlorine as an illustrative example, followed by a question on xenon.

This sheet is intended to provide practice in identifying and naming functional groups in organic substances. This is an important skill that repeatedly comes up in exam papers. As a theme, natural dyestuffs found in plants are used. There are five examples over two pages.

Applying knowledge of the chemistry of functional groups to an unknown organic compound is a typical exam question.

Exam boards often take unknown substances and ask students to apply their understanding of chemistry to them. To provide practice answering this type of question, I am developing a series of worksheets with this type of question. The series is called Practicexamquest. There are six questions.

A simple, very much introductory worksheet on this topic. Information on the front, a few questions on the back.

A simple cut and stick exercise to consolidate. In black and white. Students love cut and stick exercises.

A simple explanatory sheet for this thorny issue.

I have improved my video of this reaction mechanism.

One of the most useful skills in answering many GCSE chemistry questions is to work out what type of reaction is involved in the question. This helps you work out what the products may be, but also answer other questions about the reaction. Students often find this very difficult, mainly due to a lack of practice and experience. This simple information sheet with questions at the back is in black and white so can be readily photocopied.

Some synoptic questions in the form of an interactive web-based crossword. Unzip the file and double click on the index (Works with edge, chrome and firefox, but not safari)

Simple animated cartoon, with narration.

I have reworked this simple video as an mp4 file for anyone nervous of html. It is a bigger download than the html version though, at 2MB.

Double click on the html file. Use browser controls to zoom in or out. Useful for discussion around the whiteboard.

This is a simple powerpoint giving names and formulae of ions. Knowledge of these can provide a key to understanding chemistry at GCSE and A level. Print these off, laminate them, and display in a prominent position in a lab. (NB I have corrected the ammonium ion error)

Exam-style questions centered around tryptophan.

2,2,4-trimethylpentane, or iso-octane used to feature heavily in the OCR Salters A level chemistry, because it is an important additive to petrol. It has slipped out of the specification, but the examiner must be sitting on many questions that might be recycled to test understanding. This is a simple information sheet that gives answers to a legacy question that one of my students was completing. It aims to answer difficulties with the question in a graphic way. The sheet runs to three pages and examines isomerism.

Join the ions that cause precipitation. I have included an answer plus an OCR table of solubilities.
