W57: Microscale Chemistry from the United Kingdom

Log in to save this to your schedule and see who's attending!

The session will show how qualitative and quantitative microscale techniques in practical chemistry, can tease out of the students a greater understanding of the particulate model of molecules and ions interacting with each other; how chemists interpret the visible with the invisible.

It will feature redox and precipitation reactions, volumetric and gravimetric analysis, electrolysis, a Hofmann voltameter, environmental, gas and organic chemistry.

Using equipment such as plastic folders, Petri dishes, crown bottle tops, plastic and Pasteur pipettes, syringes, very robust carbon electrodes and accurate microbalances, the participants will carry out most of the activities and asked to offer more possible applications of the techniques.

Positive comments point to the reduction of wasted lesson time allowing more discussion and questioning, better classroom control with less walking about, students able to work on their own, reducing working memory overload and improved safety. It also addresses green issues such as less waste.

I taught 11-18 year old students for 20 years and now for the last 22 years I (although retired - hah) continue to work as the chemistry adviser for CLEAPSS, www.cleapss.org.uk, a UK organisation, to which all high, middle and primary schools in England, Wales, Northern Ireland and many parts of the world, subscribe. It provides support and advice on practical activities in science, D&T and art to teachers, technicians, Head Teachers, School... Read More →
