I chose to cover luminous sources using this cooperative learning activity (CL) as a way to make the topic more interesting and meaningful to the students. Students can be easily grouped according to the light source for which they are responsible, another reason why this activity works well. It is truly remarkable that once all the instructions (see Instructions sheet) were given out, the students were engaged — working quietly and attentively as they knew they all had roles to perform. Giving a time limit for the various parts of the activity ensured students maintained their level of readiness/involvement.
