<p>Biomedicine workshops in the Science Park terrace. <br /></p>
11 May 2007

The goal of this activity, entitled “How does the scientific method work? Let’s do biomedical research!”, is to stimulate the creativity and thinking in students between the ages of 10 and 12, and to contribute to their educational activities. The project is part of the PCB’s “Science and Society” outreach programme, which aims to help improve the scientific culture of society in general, to promote research, and foster vocations in this field.

During the activity – which lasts from 10 to 12.30 in the mornings – students attend a theatre workshop in which two crazy scientists complete experiments using the scientific method, while explaining the function of cells, DNA...
