CLEAPSS Supporting practical science and technology
Welcome to the new CLEAPSS Science Website
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)

COVID-19 (Coronavirus) in Schools - Updated 10/07/2020
Latest News

CLEAPSS office is  closed following government advice.

We will however continue to answer ALL helplines, and continue to develop both emergency guidance for COVID-19 and longer term developmental guides across all the areas we cover.

Returning in September Guidance 
CLEAPSS is currently working with DfE and other agencies reviewing the latest DfE guidance for schools returning in September. 
We will publish our updated guidance in response to this in early August when the DfE confirm that this guidance is being implemented.

If you have an EMERGENCY Helpline i.e. pupil with chemical in their eye, a chemical spill, or radioactive issue. 
Then please call 07565 114 059 (available 8.30am-5.30pm weekdays)

If you have a more routine question e.g.  what is my password, can I pay an invoice, or technical question. Then please email it to

Please do NOT call the above mobile number with routine questions.

Primary schools should refer to our primary website for their guidance on managing practical work.

DT Staff should refer to our DT website for their guidance on managing practical work.

Please continue to check this web page for updates, and follow our Twitter account (@CLEAPSS ) for more updates.

Following government advice, CLEAPSS has cancelled all our courses until the end of July. 

We have now created a series of new guides to support schools during the COVID-19/Coronavirus Pandemic :-

Check your chemical store!
One thing to do BEFORE schools shut down for the summer holiday.

Make sure you check the chemicals in the chemical store are secure, not leaking and stored appropriately e.g. ensure there is water surrounding your 2,4DHP(H).

Refer to guides GL246 and our chemical stocklist E233 for more guidance on how to do this.
CLEAPSS Podcasts
CLEAPSS is now running a new series of Podcasts, the first edition is with Dave Parry our DT adviser discussing the new DT MRATs (Hazcards for DT).

Episode 2 is now live and about radioactive sources and your RPO/RPA.

Episode 3 is now live and with 'Uncle' Bob all about Hazcards and SDS's.

We intend to record more of these in the near future.

New Log In Details
The new login and password has been sent to members via the printed bulletin.

As part of the move to online membership processing, direct members of CLEAPSS (ie not via a local authority or other brokering organisation) will have been sent a renewal notice by e-mail. We have sent out over 2500 electronic requests and so far almost half of those we have contacted have successfully navigated the online membership renewal process.If the renewal request has been passed to you by someone else and you are not sure what to do next, give us a ring (01895 251496) and ask us to resend the renewal directly to you. That way you can simply click on the link in the e-mail to access the online portal. 

If your school has not renewed its membership by the end of January, membership will lapse and your password will stop working.
CLEAPSS at the ASE Conference 2020
CLEAPSS once again had a large presence at the ASE Conference.

We had a stand (AS10) where you could collect your latest #CLEAPSSMug, please tweet pictures of your mug in use (via @CLEAPSS).

We ran lots of workshops, which you can find exact detail of here

The resources linked to the workshops you can find here.
