Comets - harbingers of doom or agents of life?

During the summer of 2012, 40 secondary school teachers from European Space Agency member states gathered in ESA's Space Research and Technology Centre, ESTEC in Noordwjik, NL to participate in a 3 day Teacher Workshop. Here they participated in activities geared towards helping them use space as a teaching tool. This session, given by Anu Ojha, Director of the National Space Academy in the UK, uses comets as a hook to bring space into geography, physics, chemistry and mathematics classes.
