Awww!!!

  • I like swimming & I like tigers.

  • My Favorite thing that we did in Bio was The Blog because we got to teach, and write about things that we were interested in.

  • This is a video of student saying why they like The Blog.





Opabinia

By: Jenna

The opabinia is an instinct creatureand was very rare. There are fewer than 20 specimens that have been found. It went extinct by the end of the Cambrian. The opabinia had five eyes and can grew up to three inches long, not including the one inch proboscis which is the long trunk like tentacle growing from the front of its mouth. The opabinia used its proboscis it search in holes for worms and then grab them with the proboscis and pull them to its mouth so it can eat, much like an elephant. The opabinia lived in the soft seabed in the sediment, but could swim around the sea with it's side lobes.
The opabinia looks like a crustacean, which would mean that it would have a hard outer shell like a shrimp or lobster. However it lacked the trait joint legsand it also has five eyes and a of proboscis, which is not a trait of a crustacean. The opabinia is very different than any animal alive today, which makes it very difficult to place in a group. Scientists believe that they are part of the arthropods. Arthropods is a group that contains the sub-groups myriapods, trilobites, chelicerates, crustaceans, and insects. Here is a video of how the opabinia might have swum around the sea.

What group do you think the opabinia belongs in? Can you find other interesting creatures that went extinct?

Student Expectations
How Will I Meet This Expectation?
How Did I Meet This Expectation?
Demonstrate ability to evaluate sources of biology information on the internet
  • I will review sources of Blogs that people write
  • I will have my peers review things that I have written
  • I will only use sources that end in .edu or .gov, because they are more likely to be reliable.
  • I have gone to the creatable sources page and reviewed sources
  • I reviewed them based on the time that they were updated
  • I looked to see if they had endings with .edu or .gov because they are more likely to be reliable
  • I looked to see if they were selling any thing on the web sights, if they are then they are usually not credible
  • I looked to see if the sources are research based, and i reviewed their research methods
  • I looked to see if the sources had sources to their infotmation
Demonstrate an ability to read and understand current biology news
  • I will read and comment to recent bio news
  • I researched opabinia for my post and only used the information that I understood.
  • I looked up all of the scientific words that i did not know so that I was able to understand the information, at this website.
  • I did not plagiarize in my post
  • I made sure that my post was biology related
  • I did not add information to my post that i did not understand
  • I read, understood and commented to Caitlin's post Vitamin D Levels in Arab-Americans Too Low, Which is very current because there was a study done on Febuary 12, 2009
Demonstrate proper use of online resources
  • I will only use sources approved by Miss. Baker or by many of my peers.
  • I will review my peers sources
  • I have put my sources on the creditable sources page and they have been review as creditable
  • I hyper linked my sources properly so that people could look at the source of the information that is on my post
  • I looked on creative commons for the pictures for my post and did not use any because i understood that they were all rights reserved and it would be plagiarizing to use them
Publish work that is available for peer-review
  • I will post Blogs on the wiki so people can check it before I post it on the blog
  • I have posted by blog on my wikki above so my peers can review it
  • I have asked Mary, Clarke and, Teddy to review my post
  • All of my sources that i used are on the credible sources page, and they have all been approved
Discuss published work with a practicing biologist in that particular field
  • I will try to find a biologist who specializes in the area that I an writing about

Provide constructive peer-review to classmates
  • I will review my peers Blog posts and try to give good suggestions about how they could improve it
  • I will comment to my peers Blog posts
Discuss in-class assignments
  • I will talk about in class assignments on the blog
  • I will try to make posts, or comment to posts, that are connect to the things that we do in class
  • I have commented to Caitlin's post Vitamin D Levels in Arab- Americans Too low we talked about vitamin D in class, which helped me understand this post. I provided a source and a little bit of information about the study
*
Apply creativity to work
  • I will make videos and take my own pictures
  • I will find new and creative ways to make a post other than writing them on paper

Chloroplast


Chloroplasts are specialized organelles found in all plant cells. These organelles contain the plant cell's chlorophyll,which provide the green color. They have a double outer membrane. Within the stroma are other membrane structures - the thylakoids and grana where photosythesis takes place. Chloroplast's have their own DNA and RNA located in the stroma.

  • Stroma- Is the tissue that supports the organs/ organelles, it also hold the DNA and RNA

  • Thylakoids-Is the membrane that converts the energy from the sun to potential energy which is the stored energy that the plant can use to do photosynthesis

  • Grana-Are staked Thylakiods that contain chlorophyll
