Reflection On Mole Day

Today we had our mole party to celebrate Mole Day. Everyone brought in snacks and drinks and I worked on work from another class. The moles that everyone crafted were creative and humorous. As I looked at all the other moles, I realized that my mole was inferior in creativity. Overall, it was nice to have a relaxing morning and be able to get some work done for my other classes.

Reflecting On Today's Test 10-27-15

Today in class we learned about dimensional analysis. We learned how to convert units by hand and were informed on what was expected of us on Friday. I also took a test today after school over significant figures and physical and chemical changes. I feel as if I did fairly well on it because it was not too challanging.  

Weekly Reflection 10-22

Last week we went through our matter and measurement unit and then had our mole party to finish the week off. It was a easy week due to the math involved.

Weekly Blog 10-9-15

Today we once again had a study/work day. Yesterday we concluded the aspirin lab and we came out with some good looking results. We scraped our acetylsalicylic acid crystals out of our beaker and put them onto a Pyrex watch glass. My lab partner and I put this out to dry over Fall Break to ensure there is no other contaminants within the product. Below are some pictures that were taken throughout the course of our experiment.
This was during the first day of the experiment. We placed the sulfuric acid, acetic anhydride, and the salicylic acid into the Erlenmeyer flask and then put it in a hot water bath for 12 minutes.
This picture is the first picture we took of the crystals after they formed overnight on the first night. After this, we scraped all of them out with a glass stir rod and put them into the top of our buchner funnel. This was a tedious process due to the fact that the solid crystals did not want to remain in the center of the filter paper.  
The picture above is when my lab partner and I retrieved our acetylsalicylic acid from the Buchner funnel. The purpose of the funnel was to separate the solid product from the liquid.

Class Reflection 10-6-15

Today, and yesterday as well, we have had study hall days in class. They have been of great assistance because it has allowed me to get 100% caught up in all my classes. While today and yesterday have been fairly lackadaisical, tomorrow my partner and I start the lab. I have gone over the procedure for tomorrow's aspirin lab and hope to ace the pre-lab quiz so I can conduct the experiment.
The picture above is showing the lab setup for the lab tomorrow. My lab partner and I must both pass the pre-lab questions so wish us luck!
