Dimensional Analysis Notes

     Yesterday we took notes on dimensional analysis. Most of it was review, but some things were new, like when you square or cube the unit, you have to square or cube the conversion factor too. Overall, I felt it was relatively easy, but it might get harder later.

Mole Day

Yesterday was Mole Day! A mole is a unit of measurement used in chemistry approximately equivalent to 6.022 * 10^23 (hence 10/23 being mole day). To celebrate, everyone sewed a mole and brought food. Most of the moles were themed and, my favorite being  the "mole dancer".

Matter and Measurement Pretest & Notes

     Yesterday, we took the matter and measurement pretest. At first, I felt like I didn't know anything, but after taking notes today, I understand a lot more than before (though there's still a lot left to learn). After notes today, we went around the room to answer questions at 8 different stations.

This was on of the easier stations

Aspirin Lab Day 2

     Today was the lab for day 2 people. Unfortunately, half of our group failed the pre-lab quiz, so I didn't get to do the lab. Luckily, one group in our class did pass, so we will have data for future labs.

Aspirin Lab Day 1

     Today was supposed to be day 1 of the aspirin lab, but unfortunately, no groups passed the pre-lab quiz. Instead, we all had a work day. This means that Wednesday, the day 2 people have to pass, or else everyone will get a zero.

Some Useful LInks

     I'm almost finished with my star log, and I thought I might share some of the sites I've been using in my research.

This website has a huge database of articles about stars that I've been using to find the Right Ascension and Declinations of stars. You can simply look up the name of a star in the search bar, and you'll probably find a couple articles on it

I've been using this website to figure out the Stellar Classification of certain stars. It has taught me how to read Stellar Classifications, such as what the number after the first letter means, and what the roman numeral represents.

Forensic Archeology

     This is the data table we created Microsoft Excel. We had to cut out 567 small pieces of paper and place them in the cup. We would then drop all our slips of paper onto a surface, and count all the slips that landed face up. We repeated this 6 times, to simulate the radioactive decay of a substance with a half-life of ten years over a course of 60 years.

     Though it was a pain to count all the tiny slips of paper, I learned a lot from this lab, and definitely have a greater understanding of half-life
