Kayleen Fahrlander Thursday Dec.6th 3/3

Class Summary
-Review heart sounds from last class
-Watch short movie clip (of a heart beating)
-Read pages 331-334 (exercise adjustment) and 338-339 (lymph system)
-Blood Assignment due Wednesday (Dec.12th)
**Homework**-Make labels for tomorrow's heart dissection (put tape over them)

Thoughts and Opinions
The more I think about the heart, the more grossed out I get about it. There are so many different parts and something could easily go wrong and stop your heart from beating. After going to bio class, I'm more aware of my heart beating and it makes me really uncomfortable. To me, this unit is a lot more interesting and useful than cellular respiration/ photosynthesis ever will be. I'm really excited about the heart dissection tomorrow!

Above and Beyond (Heart Facts)
-According to German researchers, the risk of heart attack is higher on Monday than any other day of the week.

-By the time you turn 70, your heart will have beat some two-and-a-half billion times (figuring on an average of 70 beats per minute.)

-Women's hearts beat faster than men's.

Sarah Nov. 29 3/3

- 1st we went over the assignments from last day
-sandwich story
-thought lab
-jimmy digestion
-experiment
-started next section on circulatory system
-did notes
-got notes sheet

This class wasnt that bad. We didnt do a whole lot and i didnt have to worry about homework cause i had all my assignments done. So far the human body stuff sucks and theres a lot of dif things you need to know. Like we learnt the functions of the circulatory system
-waste removal/transport gas, nutrients
-immune system
-blood clotting/healing
-body temp
you need all these to be in homeostasis which is internal balance. Thast all we really learned which wasnt a whole lot so class wasnt all that bad.

http://hes.ucf.k12.pa.us/gclaypo/circulatorysys.html#AMAZING%20FACTS

This site claims to have amazing fact about the circulatory system. They're not that amazing but i though I'd share.

-One drop of blood contains a half a drop of plasma, 5 MILLION Red Blood Cells, 10 Thousand White Blood Cells and 250 Thousand Platelets.
-You have thousands of miles of blood vessels in your body. "Bill Nye the Science Guy" claims that you could wrap your blood vessels around the equator TWICE!
-Keep your heart healthy...it's going to have to beat about 3 BILLION times during your lifetime!

Brianna Melcher, November 26, 3/3

Today in class we:
  • Took some notes.
  • Learned about the digestive system.

Thoughts and Opinions:

I think the digestive system could be important to learn if you wanted to be a doctor, but I find it boring and kind of pointless considering your body does it for you so why know how it works?

Memphis Vanbeselaere, November 20, 2007, 3/3

Today in class we:
  • Did a lab, which involved making models with candy to represent the stages of Photosynthesis.
  • Worked on review questions once we finished our lab.
My thoughts and opinions:
I think this lab had great potential, although it seemed very unclear and confusing. It esspecially didn't help if you didn't understand the stages of photosynthesis to begin with. However once you got through the confusion I thought the lab helped me understand Photosynthesis a lot better.

Above and Beyond!

Here is an interesting video that explains photosynthesis. It's a tad bit more in depth than what we've learned but still a good video.

Here is another video. It's kinda funny too, and the music is pretty hardcore. :D

Rebekah O'Brien, Nov. 22/07


what we did:
  • finished the nutrients worksheet (carbohydrates/ lipids/ proteins)
  • looked at enzymes
    • took notes from the board (section 8.2, pg. 254-258)
    • went over questions on pg. 258, #1, 3, 11 a) b) c)
  • got a digestive system handout
    • started taking 1st page of handout notes
thoughts and opinions:
  • the material covered was all pretty straightforward, but i wondered how many amino acids are there in a protein?
  • but i'm not looking forward to the PS and CR UNIT TEST tomorrow!!!
additional info:
  • apparently there are about 288 amino acids in one average sized protein molecule!
(i couldn't get a picture of a protein molecule on here, but go to google images and type in proteins and amino acids, and you can see lots there)

Christina Rose: Monday November 20th, 2007: 3/3

What we did in class today...

  • Spent two blocks recreating photosynthesis with candy.
  • Worked on review questions.

Thoughts and Opinions...


I think the lab was a good idea. it helped us see photosynthesis visually, and helped us figure out what we know and need to know. The only part that I didn't like was that it was a completely open ended lab. You had to figure out every last detail your self with out aid.

Above and Beyond...

A overview of photosynthesis.




The Calvin- Benson Cycle.

























Light Dependent Reactions.

What we did in class today...
  • Pre-Lab Quiz
  • Seperating plant pigments from leaves Lab

Thoughts ad Opinions

Last night we had to read about the lab, and get an idea of what we were doing in the lab for Friday. The pre-lab quiz was useful because we were supposed to already know what we are doing in the lab, but for those who didn't go over the procedure still had an idea from when we marked the quiz. The lab itself was simple, enough that we got started and completed it in the time provided. I was suprised that it worked, and we could see that the pigments clearly seperated on the chromatography paper. The only uncontrolled variables that would alter the results slightly were the amount of spinach pressed on the paper, and the amount of solution used in the test tube. Other than that, this lab was easy, and effective.

Above And Beyond

Like Dylan, I found a cheezy video on u tube, but on photosynthesis instead of Cellular Respiration. The video is brief, but does explain the light dependent reactions we are learning about.
