Graffitti Exercise

In today's class, we had to read from page 1 to 7 in the green booklet "Nature of Light". After that, 3 students were assigned in one group and had to give examples for a the following question on a coloured paper and switch to another group to answer another question in every two minutes. Students switched papers about three times and Mrs. Kozoriz went over to the head board and put all of the answers that was written on the coloured paper. Nearly end of the class we were assigned to do an assignment which will be due on friday called "Concept Map" I hope that you can understand what I'm trying to say.
