This experience report presents some situations involving the work of prospective teachers of courses of exact sciences with the Geogebra software. The work was developed based on a university extension course. Its aim was to introduce students to a dynamic geometry environment, and explore its potential use in Elementary and High School math classes. This paper highlights some episodes that occurred during the course, evincing investigative activities in a computational environment that were explored by participants. In particular, it reports an episode which places prospective teachers in the so-called risk zone.

Keywords: Mathematical education, Dynamic geometry, Geogebra, Risk zone.
