1/9

In class, today we turned in 34.4 Flow Map on "Fertilization, Development, & Pregnancy" which was assigned on Friday as homework to do over the weekend. After, we took out UP 20-21 and we first went through the answers with the people sitting near us and then we went over the answers as a class. We didn't turn in UP 20-21. Next, Mrs. Stein has us work on Lab 31 with anyone we wanted. Even though, you were supposed to have it done for homework she let us talk to our partners about any questions we had trouble on. She walked around and answered questions while we worked on it. We worked on Lab 31 for about ten minutes, and then we turned it into the bin. Finally, we took notes on two slides that Mrs. Stein put up on the smart board.
Here are the notes:

Contraception
-preventing union of egg and sperm
-barrier method
- condoms, diaphragm, vasectomy
-chemical methods prevent gamete formation or kill gametes
- The pill, IUD, spermicide
-behavioral changes in sexual practices
- abstinence, rhythm, withdrawal

Fertilization and Implantation
-fertilization occurs in oviduct
- zygote- fertilized egg, diploid cell
-cell division begins

Since there isn't going to be much homework this week make sure you don't slack off and actually start studying a little each night for the TEST ON THURSDAY!! Just because there may not be mandatory homework DOES NOT MEAN you shouldn't study. Remember studying is part of the homework so do it, and don't procrastinate until the last minute!!

Andrijana will be our next scribe!
