We did the fetal pig dissection and it was really interesting to see the heart and the intestines. The fetal pig showed how everything Is all connected from all the. This was a very valuable expiriance and learned a lot from it.

how much urine can a bladder hold?
A normal adult bladder can hold anywhere from 16 to 24 ounces about 500 to 750 mL before the urge to urinate becomes overwhelming. Everyone's bladder is different though, so some can hold more than that amount, some less.
PLAYLAND!!!
- Heart Rate: how does waiting in line for a ride affect your heart rate? Did you record your heart rate before and after (any evidence)? How about riding on the ride - what affect did it have on your heart rate?
- Why do you think your heart rate is affected?
- Breathing Rate: Was your breathing rate affected by the rides? Which ones?
- What other physiological effects (on your body) did you experience? Can you explain any of them?

I may be short but but i have big lungs!
so we did a vital capacity test in class and it tuned out that i got the second highest in class wich was a 4.1! yeah i can hold lots of air.
1. How does your vital capacity compare to others in the class? Describe some reasons why you think your vital capacity is what it is. Why are the highest and lowest vital capacities the way they are?
-your vital capacity compared to others in class can all vary depending on how we all exercise our lungs some people are more athletic or some people play intruments.my vital capacity is the way it is because i may be short but i have a big frame compared to other girls in class. the lowest vital and the highest capacity are the way they are because some people have bigger or smaller body frames and it depends on how they exercise thiere lungs.
2. How much air is in a usual breath? Why are our breaths the volume that they are?
-There is 500ml of air in our usal breath we only breath that much in order to conserve our energy.
3. How is the mechanism of exhaling forcefully different than a usual exhalation? Why would practice at this via exercise/instrument playing/singing make you better at it?
-Breathing for us is automatic no need to think about it we just do. just like any other muscle in our body if we work it the stronger they will get that is why when people who exercise or play insruments have stronger lungs they are consitanly working them out.

i made a lung!!! yeah just one.
So, we learned how we breath the contraction of the diaphragm is what occures when we inhale, and it relaxes when we exhale. When we breathe, the ribcage expands to allow the lungs enough room to inflate. When the diaphragm contracts the air rushes through the trachea and into the lungs. They deflate when the diaphragm goes back into it's resting position that part requires a muscle contraction of the diaphragm.

Bio 12 Interim Report.
1. Provide an example of a experience (or more than one) where you felt successful in class.
An experience that I felt very successful in was when i finished my digestive system project. When i finished that project I had memorized the whole digestive system I felt very proud.
2. Write about your work habits in class - if you look through your binder is there a lot of unfinished work? Have you handed in all your assignments? If not, why not? Provide evidence if possible.
When I look through my binder I see all my work done and I have handed in all the assignments that need to be handed in.
3. Have you had a chance to work collaboratively with other students in the class? How has that enhanced your learning? Or not?
Yes. I got to work with some of my friends in labs and in a project worked out very well. We did a good job on our lab and finished it on time. And I did a digestive mind map that came out wonderful.
4. What goals do you have for Biology 12? What do you need to do to get there? If your goal is about a mark, please reframe that into the work/learning that you hope to achieve?
My goals are to do a better job and to try my hardest in order to achieve what I want.I also want to get a mark in that I know I deserve from all my hard work.

Today we watched in awe as a the laws of gravity were supposedly defied by the mighty hydrogen bonds.
After watching this video.... http://www.youtube.com/watchv=7ctaA2mERzI&feature=player_embedded
we remain convinced that this is a falsity!
Hydrgen bonds found in H2O, can only withstand so much before gravity takes hold. We became experts on this subject after yesterday's experiment wherein we dropped this magnificent compound onto an ordinary penny one tedious drop at a time. In this endeavour, we found that a small bubble of roughly 20-30 drops of water formed before it's collapse. It is for this reason that we find this video to be slightly... very exaggerated. An ordinary cup of water would not be able to hold its shape once the cup was removed, that's one of the defining aspects of a liquid.
Sincerely, scientist Evelyn and Scientist Adrielle.
