Science Class of Thursday, May 19
Hello everyone, in my scribe post I will be giving a summary of Thursday’s class. Enjoy reading and be sure to check out the links.
We started off the class with talking about some final details of the CERN trip to Geneva, Switzerland. After that, we reviewed the order of everything. Here is the order:
?-Quarks-Protons/Neutrons/Electrons-Atoms-Molecules-Elements-Compounds/Mixtures-DNA-Cells-Tissues-Organs-Systems-Organisms-Species-Genus-Families-Order-Class-Phyllum-Kingdoms-Biomes-Planets-Galaxies-Clusters of Galaxies-?
- Cells are the basic units of structure and function
- All cells are created by other living cells
- All organisms are made up of cells
- One square centimeter of skin holds 100,000 cells
- Cells weren’t
discovered until the late 1600’s - People couldn’t see them, but when microscopes were invented, it was possible to see cells
- There are two types of cells
- One type is Prokaryotes cells, they have a nucleus and are very small
Microscopes:
- The first cells were discovered using microscopes
- The first microscope was a tube with a lens at each end
- The first light microscope was made in 1886 and magnified 1,000x
- Electron microscopes were created in 1933 and magnified 500,000x
- In 1981 the first tunneling microscope was made and magnifies 1,000,000x
- Tunneling microscopes go inside of a living thing
- Today only light and electron microscopes are used
- A common lens used today is convex, which are in eyeglasses and magnifying glasses
Ms. D told us to get with a partner and then grab a microscope. She gave us some safety and usage tips about using microscopes, for example, hold the microscope by the base and the arm, or, make sure to start off with the lowest powered objective and put it back at that one too. She gave us slides with small things on them, like volcanic ash or blue wool, and then we got to look at them under microscopes. I think the best view was with the middle objective, which was 40x, because it wasn’t too far away or too close. We finished up using the microscopes and put them away. For the last few minutes of class, Ms. D reminded us of the last few critical details about the CERN trip. Then that was it for Thursday’s class.
Real Life Example
I don’t know if you’ve heard about this recent debate in the USA and other parts of the world. It’s about stem cell research. To extract stem cells, embryos inside of people are killed. Embryos are vital for reproduction and many other things inside the body. There was a recent article about in the NY Times. This is another article from the University of Wisconsin about the history and more information relating to stem cells.
I hope you all liked reading my scribe post for this quarter.

This post was great Ben,
ReplyDeleteIt was not too short and long enough to not be boring to read. You had great and informative pictures with captions, you also had some nice links that were hyper linked. Your text was also nicely colored and easy to read, but there was one section of your post where one of your pictures cut off some of your text. The last thing is, you had a list in order of the smallest to biggest things, for before quarks you have a question mark, I know that these are theoretical and I don't know if your class has talked about them, but you could have included strings and I think that it would be even more appropriate now that we have all been to CERN.

Hey Ben,
ReplyDeleteGood post and great coverage of everything we did on the thursday before the trip. You have labeled pictures that match the topic, but the labels on the animal and plant cell pictures are very small and difficult to read. You used good color and had good links, but the first link to the game (very cool) doesn't stand out in color, making it hard to find. Your first part of this post, the blue text, is a bit confusing. First, you don't really say what we talked about for our trip; you just said that "...talking about some final details of the CERN trip to Geneva, Switzerland." Second, you don't explain clearly what we finished up next. You just called it "order of everything", which isn't clear of what order everything is in. For the list that you gave, you maybe could have explained what the question mark meant just for a bit more clarity. For your labels, you should probably have two more things listed: Cells and Microscopes. Your grammar is good and so is spelling, good work overall.

Ben - This is a well written post for the blog. You have covered everything we did during the class. Although I don't agree with your Prokaroytic and Eukaryotic information. Make sure to check these before the quiz. Your coverage of microscopes is thorough and I like the pictures you included. Your labels are a bit too vague, as you did not include cells or microscopes and they were a focus of this post. I think your strength this time lies in your links, but I do agree with Nathan in that the first one is hard to find. However, I love that site and am glad you brought it back to my attention. Spelling, grammar and sentence structure are all very strong as well. Nice job on your last post of the year! ~Ms. D.
ReplyDeleteHey Ben,
ReplyDeleteThis is a really good post! You had a lot of information on microscopes, cells, etc and you really did cover it well. You also included a lot of links. The few things you could have changed are CAPTIONING your pictures, adding more links about microscopes, changing the format in the beginning (there is a line break after every bullet) and like Ms. D said, change the labels. The first link is not really recognizeable. Your science is good, but I think that prokaryotic cells DO have a nucleus and eukarytoic ones DON'T. That's quite important. Other than that, you have definitely improved as a blogger this year! Keep it up! :)
Hey Ben
ReplyDeleteI think you Improved a lot and you had such a great info a bout everything and you coved important things that we did in science class. I really like everything, and I think you included enough science. But the few things that you should next time are the colors of some of the paragraphs, and you links and by links I mean that you should put youtube link of something that might could helps us better.

Ben,
ReplyDeleteNice post overall You did a good job in including a real world example and the link about the order of things from largest to smallest was interesting. I might have been a good idea though to include the names of the quarks which are top,bottom,up,down,strange, and charm. Your post also seems a bit stretched out with a lot of empty space. Overall a nice post. Bryce
Hi Ben! First off, your pictures, colors, hyperlinks, and spelling and grammar are all good. I also liked how you added a real life example to your scribe post. It makes you see how cells really do relate to real life and it makes the post more interesting. One of the only criticisms I have is that you could have made the order of everything clearer and explained the question marks. My other criticism is that, like Ms. D and Viktor have mentioned, your descriptions of Prokaryote and Eukaryote are a little off. Other than those few things, good job!
ReplyDeleteHi Ben I liked your post. I liked the fact that you mentioned the trip to Cern. Your writing was overall good. Your font was clear, but there was too much space between sentences. In the third paragraph the link is hidden, next time put the link in another color so every one can would be able to recognize it. Under the picture there were no captions, and it was pretty hard to understand which picture was the plant cell and which one was the animal cell. The labels on the pictures were very small. I am not sure why did you label the post with Cern, because that is not what you are talking about. Overall good job
ReplyDeleteHey Ben!
ReplyDeleteGreat job on your last scribe post! I liked your links and pictures, and the length was appropriate. Though you forgot to caption your pictures, their position in the post was helpful. I liked the fact that you gave the definition of a cell, but I think you could have gone more into detail about the two types of cells because for those of us who aren't in your class, it's new. Besides, the information about the two types of cells is incorrect. Overall, though, nice job!
