Kat Vanderzwan - Nov. 15/2007 - 3/3

What we did:

• Kyle drew a picture of a plant cell on the board, and a picture of a chloroplast. We went over his drawing and reviewed most of the stuff we learned about chloroplasts in grade 10.
• We talked about the thylakoid, grana, stroma and chlorophyll. The thylakoids are the site of "light independant" reactions of photosynthesis. Stacks of thylakoids form the grana, and the grana are connected by stroma.
• We also talked about light and dark reactions. Light reactions or light dependant reactions convert sunlight into chemical energy. Dark reactions or light independant reactions require the products of light reactions, they take them and preform further chemical processes on them. There is two dark reactions The Calvin-Benson Cycle and carbon fixation.
• We watched a short movie on photosynthesis.
  

Thoughts and Opinions

We had a double block today and those usually go pretty slowly, and so now that I think back to it I have a hard time differenciating between the two classes. I think that today was useful in reminding us what we already know, but at the same time a little bit tedious because we already knew some of the stuff. Today was a slow class because some of it was review, but I was a little suprised at how much kids in the class forgot from last year. We did learn some new stuff today, but I'm doing this like 5 days later so I'm having a hard time remembering and I might have added stuff that we learned on Friday, Monday or Tuesday. Oh well. Personally I think that this topic is pretty interesting and I wonder why someone looked at a plant and was like "I WONDER WHY IT'S GREEN!?" because it seems like one of those things that just are, y'know? But who knew that there was so much stuff to it? Photosynthesis is pretty complex.

here is a song i found about photosynthesis, im pretty sure that we're at a deeper level then this song is. but hey, it's a good time!

What we did?

• took some notes on cellular respiration
• reviewed the 4 stages of C.R many times
• looked at how ATP was formed handout

What I think?

• I find it really confusing and I don't really see the point of learning about cellular respiration because I don't have to do it my body does it for me, which is great. I can't imagine having to do C.R myself, I would most likely be dead guy.

Above & Beyond

• when i think about the "great" topic of cellular respiration i can't stop to think....is there an easier way, i did some research and the answer is no! So i thought I would just talk about some interesting facts about C.R...oh dang there arn't any but I did find a cool cellular respiration song at: http://www.youtube.com/watch?v=fmyby8zWeSU

I can't believe someone made a song about cellular respiration...haha

What we did:

• Marked Cellular respiration sheets from friday.
• Took some notes and review.
• Went over the ATP formula sheets

Thoughts and Opinions

The class was kinda slow. we didnt get any homework or anything today. dont really see how this is something that we need to know for a career unless you want to be a genetic scientist.

Above and Beyond

Through the class the use of glycose in our body and where our body gets them from (simple glucose, complex glucose, fat, and eventually protein). From this I wondered (as creepy as it may seem) how long would it take for the body, without food to finally resort to eating its own protein? Here was what i found http://www.goaskalice.columbia.edu/1340.html.

Finished quiz on evloution
Marked quiz
reviewed for unit test on wednesday with a Jeopardy game

Evolution is an amazing thing to learn about and with every turn there is something new and exciting to find. You never know what will happen.

Remember to Study for your exam on october 31. 2007 and have your worksheet done so you can write it.

Class Review:

- Handed in late Bio Field Projects.
- Marked homework.
- Learned about embryos, homologous and analogous features, vestigial features and similarities/differences in DNA.
- Did Analysis assignment.
- Went through and took notes on "Early Beliefs about Evolution" handout.

Thoughts and Opinions:

Its crazy to think that all of the evidence that we base our evolution and scientific history on is as much as we could fit in the back of a pickup truck. I had never thought of it that way and it amazed me. Its interesting how closely related some species are to others. For example, the T-Rex and the chicken. It was hard to picture that image in my head. Overall, it was an interesting class and I learned a lot of new information. I'm just wondering, what species humans are the closest to?

Additional Insight

http://www.amnh.org/exhibitions/permanent/humanorigins/past/dna.php

The chimpanzee and another ape, the bonobo, are humans' closest living relatives. These three species look alike in many ways, both in body and behavior. But for a clear understanding of how closely they are related, scientists compare their DNA, an essential molecule that's the instruction manual for building each species. Humans and chimps share a surprising 98.8 percent of their DNA.


The light and dark bands on these chromosomes, created by a laboratory dye, reveal similarities and differences among human, chimp and mouse DNA.

Class Summary

-Hand in quadrat projects
-Take notes from over head on 1st hand out (fossils/evolution)
-Do questions on 2nd hand out (fossils/evolution)

Thoughts/Opinions

- Evolution is such an abstract concept because it's hard to imagine that every living thing may have come from a single one-celled organism.
-Many people may be skeptical of evolution because of religous beliefs, but there is serious evidence (through the study of DNA bases) that proves that some organisms are closer related than we think.


Above and Beyond

Oldest Fossil Ever Found-A team of Swiss and Austrian geologists found some 3.45 billion-year-old dolomite in the Pilbara range in North West Australia. After etching it with acid they found the fossils using an electron microscope.
It is believed that the fossils are of a cyanobacteria - an organism that still forms thick mats in warm shallow seas today.
In the early pre-Cambrian period, they played a vital role in the development of more complex species by being among the first life forms to use sunlight to help them absorb carbon dioxide and release oxygen and therefore making the atmosphere breathable.

Today we learned about evolution . the kingdoms of certain species .

I think this class is super fun :). The topics we discuss are fun and educational.

I have no questions
