Aspirin screen experiment


The aspirin screen experiment is an interactive resource which allows you to run your own experiment. Each of the four levels take approximately 30 minutes to complete and are designed to be used as pre-lab activities in class or as homework.

Hands-on practical activities or ideas for front of class demonstrations


The aspirin screen experiment has been designed to be a flexible open tool for teachers and students. The synthesis of aspirin is an organic chemistry experiment in many specifications for students of ages 16-18 years.

This resource allows students to run their own reaction online before taking part in the real thing. The advantages to this approach are that the students will become more confident and familiar with the procedures in the laboratory. They may also feel less rushed and better understand the reason for each task. After using this resource feedback suggests there is more time in class to focus on practical skills and developing understanding.

The Royal Society of Chemistry would like to thank Dr Simon Rees (Chemistry Teaching Fellow, The Foundation Centre, Durham University) for his help and advice during the development of this resource.
