Another day at science

HW- u.p. pages 73-76

and continue the

plant project.

-today in class we reviewed the homework from a few days ago, which was pages 81-85.

-We reviewed all the things we previously knew about photosynthesis and the structure of a chloroplast

-In photosynthesis there is a light dependent and light independent cycle

the light dependent cycle takes in sunlight and water.

When the water is split to form ATP oxygen is released.

-Once enough ATP and NADPH are created they go on to the light independent cycle, or the calvin cycle. In this cycle the energy from the ATP and NADPH is released and combine with other things, like carbon dioxide, to form glucose.

Last day of November already?

Today we finished learning about meiosis( is that how you spell it?). We took notes on meiosis phase 1 and 2. The chromisomes only replicates during INTERPHASE which it goes through once. We also talked about how the chromisomes will cross over, while doing this they can exchange genetic information.

During Meiosis the chromisomes do not line up at the center like the do in mitosis, they are in more of a box formation. After meiosis 1 and 2 you end up with 4 sperm cells in a male, but in a female only one egg will survive.

the HW is finish pages 29 through 31 in the packet and read chapter 11.1
The next scribe is Tara.

Friday Blog post

Today we started class by going over the previous post and talking about influenza. The disease of the day. Influenza is a virus and it can be spread by saliva and mucus. You cannot get rid of influeza it just goes dormant.

Next we started 2 labs. One on page 13 and the other on page 16. We received 2 petri dishes. For the first lab we took the one with the cross shaped divider and labeled the sections on the back 1-4. Then we took samples of 3 different places around the school and put them in sections 1-3. #4 is the control group. Then they were put in an incubator.

For the second lab we took a petri dish that was not divided but on the back we still labled 4 sections. then we took 3 different kinds of antibiotics and one little piece of paper and put them in each section. One antibiotic in each section but 4, which had the paper in it. We put this in the incubator too.

Something about cells

TODAY IN CLASS: Today we went over the functions of some organelles and what they looked like. We also got homework that I will list at the bottom of this post. We began to work on a color coding packet which is homework. We shortly talked about the similarities and differences between plant and animal cells.

Other things like HW: -Do color coding with annotations in the color coding packet.

-Read Pg.226-228 and Pg.250-251 and do check my understanding,make one row for things you knew, one for things learned, and one with a minimum of 3 questions.
