SCI-FUN Do-It-Yourself Activities
Based at the University of Edinburgh, the SCI-FUN Roadshow has been delivering interactive activities to school and community groups for 25 years. On this page, we share some of the activities that can be reproduced at home or in the classroom with the use of some basic materials and perhaps access to a printer.
If you have any trouble with these materials, or would like to send us any comments about them, please contact us:
The activities are grouped below by how difficult they are to recreate.
