CLEAPSS Supporting practical science and technology
Welcome to the new CLEAPSS Science Website
What is CLEAPSS
CLEAPSS resources give teachers ideas for exciting and engaging practical activities that fire pupils' imaginations and then, unlike many other sources of ideas, go on to show teachers and technicians in detail how to translate the ideas into safe and exciting experiences in the classroom.
CLEAPSS advice and documentation is recognised by the Health and Safety Executive and the Department for Education.. (read more)

Copper Sulfate
CLEAPSS has recently received multiple Helplines about incidents with copper sulfate. 

This includes situations where pupils are deliberately consuming Copper Sulfate, please ensure you enforce the no eating / drinking rules in your labs and also are aware of how to deal with emergencies.

E-cards : How to deal with lab emergencies

No eating or drinking guidance 

Please also review the updated Hazcard before using copper sulfate.

2025 Hazcard updates includes and update to the safety advice for copper sulfate. Hazcard 027C - Copper Sulfate


A quick and safe method for preparing hydrated copper sulfate crystals and beautiful blue crystals may be obtained within 30 minutes.
CLEAPSS and LabLogger are collaborating to support practical science!

The collaboration will use anonymised requisition data from LabLogger to build a picture of school science practical work. Participation is entirely voluntary (opt-in), and no personal data is shared in the process.

Real-time anonymised requisition data has the exciting potential to provide unique insights into what practical activities are actually taking place in schools across the UK.  The data will also allow CLEAPSS to track data over time to build a more accurate picture of trends and providing answers to questions about the perceived decline in practical work.

CLEAPSS also plans to use the findings internally to identify areas of practical work where it can offer more tailored support as well to support CLEAPSS’ research and advocacy work to strengthen the place of practical activities in science education.

So, we need your help!

If you would like your school to participate in this exciting project and help us achieve these ambitious goals, all UK-based schools that use LabLogger can now activate the new Share our anonymised Request History data with CLEAPSS setting on their Account Settings page.

More information on the new setting, as well as a short Q&A, is available by clicking on the information-icon on the top-right of the ‘Account Modifiers’ section of the Account Settings page on LabLogger.

If you want to know more about read GL489 our FAQs guide about this project.

Eye protection; a change in standards
Eye protection; a change in standards

The standards for eye protection have recently been reviewed and updated to an ISO (worldwide) standard. 

Although the new standard is more demanding than previously, there is no need to replace your current stocks. 

Suppliers will start to sell eye protection to the new standard during the autumn term, but they can still sell existing stocks to the old standard. Therefore, the likelihood is you will end up with a mixed stock of eye protection to either standard for a while. 

Safety glasses were labelled EN166 and will in future be labelled EN ISO 16321 C Safety goggles were labelled EN 166 3 and will in future be labelled EN ISO 16321 3

Existing products certified to EN 166 can continue to be sold until the expiry of their certification, up to a maximum of five years from the date of issue. 

For example, if a product is certified to EN 166 before the November deadline, it may remain valid until late 2029 depending on the certificate’s issue date. BSI have a blog about this change.

We also have a buying guide for eye protection

This information is simply to inform you about the upcoming changes. For a while, both standards will be in use. 

You do NOT need to replace your current stock of eye protection — you can continue using them until they are worn out. There is no set deadline for users, so just be aware that you will have a mixture of both standards
