Relative Dating

Monday was Labor Day so we did not have school.


 On Tuesday in science class we began reviewing for our quiz on Wednesday. We went over some new rock terms used in relative dating. Relative dating is when you classify rocks with no certain number but in chronological order like youngest to oldest. Also in addition to that, we did a worksheet focusing mainly on relative dating and on the back we added some new rock terms. The pictures we drew with the terms really helped me understand the main concepts and helped me study for my quiz the next day.


On Wednesday we had our quiz. I think I did okay but in my opinion some of the rock questions were worded weird. I studied for about an hour but one thing I could improve on is double checking the notes to get any information I might have missed. Along with the science quiz we had another science Olympiad meeting. I am super pumped for this year and am glad to be a part of the whole thing.


On Thursday we reviewed our quiz we took the day before. I did not do as well as I hoped but there is always room for improvement. Since we had a substitute we finished the note cards for unit two. Most of the note cards we added were words I was familiar with but had no idea what they meant. Before doing these note cards I had no idea that Pangaea was when the earth was one large supercontinent(also a vocab word) that began to break apart with a process called uniformitarianism . I now know from the quiz that Hutton came up with the term uniformitarianism not unconformity.


On Friday we reviewed our notes cards we did the previous day in class. After that we started section 5 of our notes. One thing I took back from the notes is the science words used by  professionals. I bet you didn't know that ga stands for giga annum which is a billion years. So instead of saying the earth is 4.6 billion years old you could say the earth is 4.6(ga) years old. One of the Latin roots you probably didn't know, unless you took Latin, is eon which means big. In science words an eon is the biggest division in the geologic time scale.

Overall this week has been a week of review and notes. Next week will be much shorter so we will not be blogging.One thing I can take back from this week is even if you do not do so well on an assignment you can always take something back from it.
