carrie blog #2 March 25th 2/3

So on wednesday we marked the investigation C and D questions. And we also have a unit test on Friday March 27th on the reproductive Unit. This includes the male and female reproductive parts. Bith, hormones involved and everything involved with giving birth and what exactly happens. Half way through the class Mr. Challoner brought out a bunch of bith control methods. We looked at sponges that have a spermicide that kills sperm, birth control pills, condoms, nuva rings. We had to compare what they did and just how effective they are. Most of them have over a 90% chance of preventing pregnancy. I thought it was a very good class, learning about all the differnt methods people invented for preventing pregnancy...where they all basically do the same thing, killing sperm or preventing sperm from getting pass the vagina.
