STD Bleach and Peroxide Activity

This bleach and peroxide activity marks the beginning of our STD unit:

 1. Every student gets a plastic cup full of water except for 3. Those 3 lucky students get a plastic cup half full of hydrogen peroxide which signifies that they have an STD, however they do not know that this is the case. Everyone thinks they have a cup of water.

2. Each student picks 3 people to share their water with. One student pours half of their cup in the other students cup and then vice versa.

3. After they get done sharting water they return to their seat and write down the names of the 3 people they shared their water with.

4. Once everyone is back in their seats they are informed 3 of them were infected with an STD. The students are asked if they know who those 3 are. Normally no one will know who they are.

5. The students are then told that the only way to know for sure if someone has an STD is to be tested for them and that is what you are going to do now. 

6. For the "testing" simply drop a little bit of bleach in each students cup using an eyedropper. It their water begins to fizz/bubble they have an STD! Remember that only 3 people started out with an STD. Of course many more students will have water that fizzes.

7. After "testing", the original 3 carriers of an STD are shared.
