Sexually+Transmitted+Disease

What does one out of four or one out of six mean? Would you get on a brand of plane that had a one in four chance of crashing? Would you get on a brand of plane that had a one in six chance of crashing? This activity will explore the probability of one in four and a one in six. Put three red beans and one black bean in a bag. Shake the bag and pull out one bean. If the bean is red, your flight made it and if the bean is black, your flight crashed. Make six flights and record you number of crashes. Now put five red beans and one black bean in the bag. Fly around the world again and see if you crash. Did everyone in your group make it around the world both times? Did even half of your group make it?



In sexually active people, the rate of genital warts/HPV is one in four and the rate of genital herpes is one in six. Surveys indicate that over 50% of high school students are not sexually active, so they don't worry about catching a disease with NO cure.

There was a three year study of female college students who were virgins at the start. Three out of seven caught HPV/genital warts while using condoms every time. Condoms helped, but it stinks for the three that caught a cancer causing virus. Only abstinence is 100% safe.

(The decision to say No to STD is made ahead of time.)
