On Thursday in class we learned about the history of the big bang, and its theory. It was first proposed in 1927 by a priest named Georges Lemaitre.
Big Bang Order:
1) We started of as NOTHING!
2) The first big bang is thought to have been equivalent to dropping a 2.2 kg's bag of sugar.
3) What we call the "Real Big Bang'' was an inflation or an expansion of the universe that interrupted the standard linear expansion shortly after the first big bang.
4) Particle Soup- HUGE amount of matter formed which gets cooler and gets a larger volume (plus, - , 0 , Q , N) In other words:
(protons, electrons, neutrons, quarks, neutrino)
5) The first elements after this were;
1) Hydrogen- (first most abundant element/ first created element)
2) Helium- (second most abundant element/ second created element)
3) Lithium- (third most abundant element/ third created element)
What happens next?
Scientists are still debating on which one of the three will happen next.
- Some say the universe will have a continual expansion
- Some say it will have a "big crunch" and it will all crunch together
- Others say that eventually everything is going to stop
At the end of class we got a Chemistry Unit Note Taking Guide and a Chemistry Packet.
In the Chemistry Unit Note Taking Guide we have to do the thirteen questions about Describing Matter which is on pg. 6-15 in the textbook.
And bring Chemistry Packet to every class from now on!!

Cornelia - Thanks for posting your Scribe post. Keep in mind, you are missing labels at the bottom, which means I will not grade it until they are there. Please be sure to read all of the directions of the assignment on Moodle. If you have questions, please come and speak with me. Thanks - Ms. D.
ReplyDeleteCornelia - Just a quick reminder - you are still missing labels on your Scribe Post. You have until 1600 this Friday, May 28th to get them on here, otherwise the Scribe Post will be a zero. Come speak with me if you have any questions. Thanks ~ Ms. D.
ReplyDeleteCornelia - you have explained The Big Bang clearly and in an understandble manner. plus, it was great that you included the homework. However, this post lacks pizzazz. No pictures, no links and no colors. Think a bit more about your layout and how you can make this information appealing for your readers. You are also missing a link to real-life, which was the newest requirement for blogs this quarter. The font you used was clear and easy to read. ~ Ms. D.
