In this class, that was a part of one day camp in a high school, this teacher is teaching about how HIV spreads. The theme of the day was "choose better life skills" and a tee shirt with this logo was given to each kid. There were more than 100 teenagers participating in this camp. The camp had four objectives, preventing HIV, preventing teen pregnancy, preventing drug abuse, and preventing harm from cosmetics. In this class of 25 kids at a time, they educated kids about body fluids and before the class started they prepared some glasses with some water in each. In two of them they had put some soda, which was clear (as a asymbol of HIV). Then they asked each student to find a partner and pour some of his/her water in his/her glass and do this twice with two different people. At the end they put a drop of phenolphthalein in each glass and six of them turned red. They showed how in the beginning there were just two with HIV, but after just two times mixing the fluids, there were six.
