Class notes on fossil fuels, fractional distillation, cracking, alkanes, alkenes, isomers, functional groups.

An in class worksheet used for understanding moles, concentration and empirical formula. Best used with a number of reinforcement activities, i.e experiments.

Uncertainties and errors in measurement, suited for IB Chemistry Topic 11. Also useful for improving lab skills with glassware.

Power point used as a starter for starter IB chemistry.

This can be used as a good way of getting students to think about how they are perceived and their reality. How do they set realistic goals? The aim being to stimulate debate.

A presentation that helps students to understand that atoms are not lost or gained during a chemical reaction. Run the presentation and you will find some examples that can be done as a warm up activity. I start with Calcium chloride and then show how water is produced. It can be shown at KS3 or IB standard chemistry too. It can also be linked with moles.

Esters, aldehydes, ketones, alkanes, alkenes, sn1 & sn2 These pptx were prepared by a PGCE student for an IB chemistry class. I think they are very good and worth sharing.

Introduction to indicators, using red cabbage as a natural indicator, in this example hydrochloric acid, sodium hydroxide & distilled water are used. It's easily edited for other natural indicators. Why is red cabbage called red cabbage when it&'s purple? There are two activity sheets with simple observation questions.

A series of mole and concentration questions that can be used as an in class activity. They can be differentiated or used as a basis for a test.

Three versions of the same test for mole calculations.
