The Primary Science Fair @BTYSTE

The Primary Science Fair will take place in person alongside the BT Young Scientist & Technology Exhibition 2025, from 8th  – 10th January 2024 at the RDS Dublin with the successful applicants exhibiting their project to the judges and members of the public on one of these three days.

For over 20 years, the Primary Science Fair has been a core component of BTYSTE.  It encourages 3rd to 6th class primary school students to develop their interest in science, technology, engineering and maths (STEM) in a non-competitive environment.  It also inspires them to become future participants in BTYSTE, one of the world’s leading and longest-running school science exhibitions.

The Rules – not too many!

This is not a competition, all schools will receive participation certs to distribute to their students and will also receive a plaque to say that they have been part of The Primary Science Fair at the BT Young Scientist and Technology Exhibition 2025. Max number of pupils is 30 per project and where possible should be made up of a full class group For smaller schools multi grade classes can put a project forward and they should be a combination of 3rd to 6th class only. We may accept more than one project per school dependent on availability of spaces All ideas will go through a quick screening process which will be undertaken by judges from the BT Young Scientist & Technology Exhibition as we may receive more applications than we can accept.


Have a full class discussion about areas of interest in their science learning. Ask them questions about what they want to do and how they want to do it, make sure they have as much fun as possible while learning and learning scientifically. Agree on the focus of your idea so that you can work on your idea. Always remember that the student have to produce a poster for The Primary Science Fair which they can use as a reference about their project and to talk about what steps they have taken in their explorations/investigations. All projects will be interviewed by some of the wonderful BT Young Scientist & Technology Exhibition Alumni and past winners and also some guest judges

Ethics and safety

Throughout their science investigations children should be aware of and encouraged to adopt safe practices. They should observe safety procedures in designing and making tasks, particularly when they are using tools and materials.

There should be a maximum of 8 students on a stand at any one time.

Please ensure that your students bring a minimum amount of bags with them as there will not be any cloakroom facility. Students should keep their bag with them at all times.
