period 2 sts biology

Today in biology we started out class by discussing and taking notes on why cells reproduce. I learned that cells reproduce for three main reasons. 1. To replace dead cells in case of an accident like a cut or wound. 2. To keep a cell from growing to large, it needs to follow the cell cycle and split every now and then. 3. To let the body grow and develop through childhood. If cells would not reproduce then we would not be able to live, grow, and exist.

After discussing we were given time to finish up the lab from the day before. we quickly set out our microscopes and started filling in our lab in our lab packets. If you did not finish the lab it is not to be completed for homework. Mrs. Stein is giving us an opportunity to come in before school Monday morning to finish it!

The homework for Monday is:

read pages 43,44 in text book skip buffers.

read section 10.3 in text book up to 52b-52d and create a flow map

Cancer paper is due on 10/25

Mrs. Steins's 2nd period STS Biology

Today science class was definitely out of the ordinary. Class started out with a series of drills, first came the no warning and warning tornado drills, then came the fire and lock down drills. I thought that class was going to be easy, but I didn't think that class was going to be extended! Soon we began our real biology class, we started out discussing last nights homework. We talked about how primary succession takes place when a whole new ecosystem is being created.This can take hundreds of years. On the other hand secondary succession is a much quicker process, this takes about fifty years. secondary succession takes place after a natural disaster hits and repair to the ecosystem is required.

we also discussed the three stages of primary succession. In the primary stage Lichens break down rock into soil, mosses and grasses start to sprout. In addition perennial plants also start to grow. For the intermediate stage shrubs pines and cotton woods start to grow. Lastly in a climax community a dense forest of beach and maple trees develops. Toward the end of class we were given about twenty minutes to work on the biom charts. What was not finished was to be completed for homework.

Tonights homework is to complete pages 35-41 in the unit packet and collect your 10 oil spill pictures
