CHaOS is a student-run society at the University of Cambridge. We organise hands-on science events throughout the year at schools and public events, visiting venues in the Cambridge area and across the country. We have almost a decade of experience in inspiring children and families about science.

All our events are staffed by enthusiastic student volunteers who demonstrate the experiments. If you'd like to know more about helping then email us at contact@chaosscience.org.uk to be added to our news email list. Over 1000 volunteers are on the list and we send a few emails each term advertising our events. Just reply if you'd like to help!

Our largest event is Crash Bang Squelch! at the end of Lent term, as part of National Science Week and the Cambridge Science Festival. This popular event normally attracts over 2000 visitors and involves over 150 student demonstrators. We also tour the country for several weeks over the summer. Read about our Summer Roadshow.

This website is for our student demonstrators. We also have a website for the general public which can be found at www.chaosscience.org.uk. Find out how to do and explain lots of our Physics, Chemistry, Biology and Medical experiments. These are not instructions just examples to get you thinking. You may be interested in some general things we have learnt about demonstrating.

The idea of this site is to try and communicate ideas between demonstrators, so please make comments, write explanations of any experiments you have demonstrated, or suggest new experiments.
