Reflection Post - German N.

Overall, I enjoyed using Blogger in this and previous quarters. It made my life easier by checking whether there is any homework assigned when I skipped school. In my opinion, next year, we should use Blogger instead of Moodle because it can be helpful for students who skipped school to find out what did the class do on the day the student skipped school. However, I also noticed some disadvantages about Blogger, such as it is not so easy to put pictures where you want them to be in your post, which I found very frustrating when I did my scribe post. Overall, I enjoyed using Blogger throughout the 2nd semester.

Stars - By German

On Friday, April 30, 2010, our science teacher, Mrs. DiPietro gave us a presentation about stars. She told us that stars differ in size, mass, color, temperature and brightness. The colors that stars have are blue, yellow, and red, and that their life cycle is as long as sun's, which is 9 billion years. If the star is blue, then it tells that the star is young a very hot, about 35,000 degrees Celcius. Blue stars can also die out sooner than other stars. If the star is yellow, then it is middle-age star. If the star is red, it is cold, around 3,000 degrees Celcius, and it is about to die.

Our teacher also explained us about the sizes of stars (see pictures at the left). First, she told us about Supergiant stars. Their size is 1000 times the diameter of the Sun. These star giants include Rigel, Betelgeuse, and Antares. Then our teacher told us about giant stars. They are 10 to 100 times as large as a sun, and these include Sirius, the brightest star in our sky. We learned that the stars come from Nebulae, and sometimes from EGGs (Evaporating Gaseous Globules)

We also learned Binary stars are stars that stay together because of gravity between them, and that there are 88 accepted constellations in our sky.

Reflection Post - German

Ireally enjoyed Blogger because it has many languages, and it sort of plays the role of Moodle, because you can check the notifications about homework that the scribes have posted, plus I enjoy the tools on the main screen of Blogger. Also, I think is is easy in some cases because of the minor comments you have to do. But the only challenges I faced were typing major comments and a scribe post. It was hard for me to do the scribe post because I didn't really remember all of the events that happened on a day a had to scribe about. The challenge about major comment was the format. First I thought it had to be just suggestions about a particular post, but in actuallity, it has to be positive comments and suggestions about the post. However, overall, I enjoyed using Blogger.
