EXIT EXAM

All the sophmores had a EXIT EXAM at Feb 2-3. I took the test to. It was very easy. It was basic stuff so even if some sophmores have an F they will still pass it. I got very tired because I had to wakeup earlier then usual. But on friday we had a day off so that was a good thing.

Mg LAB

Yesterday we did a lab about Mg. We were trying to melt the Mg but unfortunately it didn't melt. We couldn't do our lab but still we got the result from the teacher and i guess it went well at the end.

this week we did a lab and we have a project to do. the project is about making a molecule webpage. i picked citric acid for my molecule. i picked this one because i knew most of what citric acid is in something. like it is in lime and lemons. now for the lab we had to do this lab where we had to heat up this matal and see if we can split it in to have if we boiled the metal. the results were that it split in to half. it was a success.

on Tuesday we did a lab where if the materials that were on the lab table were conductible or not. most of the materials that were on the table weren't conductible. only 2 out of i think 7 of them only worked. i thought the materials that were liquid would conduct. But i was wrong. none of the materials that were liquid conduct. I guess since we were using a small amount of electricity the liquids didn't conduct. well I had fun with the lab and I would want to try other stuff see if they can conduct.

Today we continued to watch Einstein's big idea. In the video, we learned how light was found and how the square root sign was found. Also today I went to Chemistry tutoring to get help on my homework. It was fun because I knew the tutors.
