Blood+Wiki


 * Hey David Lee here. I thought that this video will be quite useful in helping us learn more about the circulatory system.**

And since the guy in the video recommended the song 'Pump your Blood', I've also attached it here. Seriously, this song's great and useful. ENJOY!!! (Watch from 2.00 to the end. You can also watch the front part for some comical relief ;P)

Dear 2E4,

I am proud of your efforts to learn how to contribute to each other's learning for the past 5 weeks. Keep it up!

When you learn to make constructive comments, you are learning the basic skills of building knowledge. In the real scientfic community, scientists do not sit at desks and listen to a teacher. They search for answers and discuss, make claims based on evidence and scientific reasoning like what you are learning to do now, and change their answers.

I think you are ready to move on to the next step. So far you are only discussing and making individual claims, it is now time for you to make group claims. Much like the indigestion wiki, I will assign each group certain questions to answer. As a group, you can discuss the question in the forum. Once you have agreed on what the answer looks like, you can post the answer in the space below. Your group mate can further improve on your answers by editing the answer on this page below. Remember your answer should follow the CER too! Feel free to insert links, images or videos to elaborate on your answer, but remember to quote your sources!
