At what temperature does chocolate melt?

This resource provides a set of videos and a practical investigation aimed at supporting experimental science in the classroom and relating it to real world experiences. In the first video Professor Brian Cox joins a teacher to find out how to set up and run an investigation to find out the time it takes for different types of chocolate to melt. In the next video he then joins the class carrying out their investigation. Further videos show Brian Cox visiting a chocolate factory and a factory which produces parts for jet engines to find out more about the melting of different materials and how this can be applied to real world contexts. A written resource guides teachers on how to run the investigation in class.
