Activity 3:

The behavioral objectives for this activity include: (1) students will be able to explain how risky behavior practices affect the rate HIV pathogens enter a population. Preparation prior to students arriving: (a) Arrange 32 clear plastic cups on a table. (b) Place 25 ml. of water into cups #1-31. Place 20 ml of water and 5 ml of clear joy dish detergent into cup #32.

Once the students arrive into class, ask each student to grab a plastic cup. The activity will simulate a person having unprotected sex. Each student will mix the contents of their cup with another person in the class making sure that they retain 25 ml. of solution. This should be done twice. Students have been informed that one person in the class was HIV positive. The test indicating a positive reading occurs when I place a drop of phenolphthalein. Phenolphthalein is an indicator for a base and Joy dish detergent serves as the base. Students will be able to visually observe how a pathogen (HIV) can easily enter a population.
