Hello everyone!
On the 13th and 14th of May in Science class we have showed our cell project to our classmates and we have worked on an assignment in order to discover the mycroscope!
For the cell project we were supposed to find a common object from our house that meets the function of the organelles (little organs) within the cell and with it make a 3D diagram of a cell!
As for the Microscope project we learned what the different parts of a Microscope are as you can see on the left:
- Ocular Lens (Eyepiece)
- Body Tube
- Revolving Nosepiece
- Arm
- Objectives (there are 3 or 4 of them on a normal microscope)
- Stage
- Stage Clips
- Diaphragm
- Light Source
- Coarse Adjustment Knob
- Fine adjustment knob
- Base
What we did was partner up with someone and cut the letter "e/E" from a magazine. After that we took a microscope, a beaker with water, a pippete, two glass slides and two cover slips. We put the "e/E" on the glass slide and put a drop or two on it. We then dropped the cover slip from a vertical position onto the "e/E" in such a way that no air or water bubbles will remain. After that we looked trough the eyepiece of the microscope trough the smallest objective (4x, but with the eye piece = 40X). We then saw that the "e/E" was seen upside down because the light refracts trough 5 lenses. If hte number is even then you will see the "e/E" as it is but if the number is odd you will see it upside down. Then we made a formula to find out the magnification power of a microscope.
Here it is:Magnification of eyepiece (e.g. 10 x) multiplied by Magnification of objective (e.g. 100 x) = Total magnification (1000 x)
Lastly, Ms. D told us what homework we have which is the blog comment, to read chapter one in our book and take notes from it.The next scribe is Alix
Hi Cip
ReplyDeleteI think that you did a very good job when writing the blog post. The pictures were very nice and the information too. You could have told more about the pieces of the microscope. Overall it was a nice blog post.
Good work, lots of info... not too much. However there are little bit too many pictures in the beginning and you could add color to the text at the bottom. Otherwise good picture of the cell, really cough my attention!
ReplyDeleteCiprian - Just a quick note. Reza has already scribed, please pick someone else. Be sure to look at the list of Scribes still available from earlier this quarter. Thanks. Ms. D.
ReplyDeleteGreat scribe post, Cip! I liked the pictures a lot, especially since not only did you take pictures of the cells, but also of the students. I also liked your picture of the microscope. I think you could have talked a bit more about the cell project. Sort of like a wrap-up. I also think you could have better introduced our new chapter, although you did a great job describing microscopes and our new project. Overall, great job!
ReplyDeleteCip - Nice blog post! I liked the pictures you included, except you could've made our "cell" pictures a bit bigger. Bu the first picture is really awesome! And at some places the pictures cut into the text, cutting the word weirdly. You could fix that (one example is at the microscope). Also you forgot to add how this relates to our daily lives! It's a new requirement this quarter! However, I liked how well you described the microscope lab. A great help could also be to add descriptions of each part of the microscope.
ReplyDeleteI really liked the ending homework picture, because it just makes me laugh.
Overall, nice post!
Cip - good work on this Scribe Post. I really like your use of color and the pictures you have throughout the post. They definitely "spice" things up. Your spelling in places is off, so next time make sure to carefully proof your work. Also, you could have gone into more depth about what the Cell Project was or included a link to Moodle. You could have also explained the Microscope Packet more. The science in places is a little to vague for someone who was not in our class at the time. Finally, you have not included a real-life relationship to what we were doing, which is the newest requirement for blogging in the fourth quarter. Overall, it was easy to read and covered what we did in class. Nice work! ~Ms. D.
