CLEAPSS: Reduced and Micro-Scale Chemistry (Secondary-Level Science)

  • 7 hours
  • 1 day


This one-day course will enable science teachers and technicians to conduct quick, small-scale chemistry in the classroom using various practical procedures such as electrolysis, precipitation and iron/sulfur reactions, among others.

Practical procedures using conventional equipment are often time-consuming and are consequently left out of teaching, which can lower pupil expectations of secondary-school science.

By contrast, small-scale chemistry is quick, saves on chemicals and offers variety in presentation.

During this course you'll have the opportunity to carry out the procedures yourselves in the laboratory.

This course is run by the Consortium of Local Education Authorities for the Provision of Science Services (CLEAPSS) at IOE, UCL's faculty of education and society.

Who this course is for

This course is aimed at secondary science teachers but technicians are also welcome.

Course content

The course covers:

  • indicators
  • electrolysis
  • precipitation
  • iron/sulfur reactions
  • working with toxic gases
  • carrying out small-scale vigorous reactions

You'll gain experience in carrying out the procedures yourself in the lab.

Entry requirements

You'll need to be a secondary science teacher or science technician in your school.

Learning outcomes

By the end of the course, you'll: 

  • be able to find information on chemicals and their hazards in school use
  • be able to handle chemicals safely for school practical work
  • have developed knowledge about storing, disposing and dealing with emergencies with chemicals

Bob works as an adviser for CLEAPSS.

CLEAPSS provides advice and guidance on all aspects of practical work in science, technology and art. This guidance explores ideas for exciting and engaging practical activities that fire pupils' imaginations and then, unlike many alternative resources, goes on to show teachers and technicians, in detail, how to translate these ideas into safe and exciting classroom experiences.

CLEAPSS has more than 28,000 schools and colleges in membership, predominantly in England, Wales and Northern Ireland, where its advice is recognised by HSE, DFE and OFSTED as representing best practice in these areas. As such it is used by employers as the basis for them to discharge their responsibilities under the H&S at work act 1999.
