Construction of an Air Bag Lab

Today we were instructed to form a procedure and equations to figure out the amount of baking soda and vinegar needed to fill a random size plastic bag. When our class first heard the instructions, we were a bit confused and intimidated. But after some deliberation we all figured out how to make this happen. After all, everything worked out and we all passed the lab! Here are some links i used as research:

Post- Quiz

After the quiz, i've realized that i definitely need to study more for the test next week. One thing i was confused on was the graphs, so i found this picture that helps.

Charles' and Avogadro's Laws

Charles' Law states that When the pressure on a sample of a dry gas is held constant, the Kelvin temperature and the volume will be directly related.
Charles' law

Avogadro's Law states that equal volumes of all gases, at the same temperature and pressure, have the same number of molecules. 
Avogadro's Law

Boyle's Law

For our first lecture, we talked about the first gas law, boyles law. Boyle's law tells us that pressure and volume is an inverse relationship.

Biodiesel Summary

In this unit, we learned about how many affects that diesel fuel has on the environment, and how biodiesel is the better choice. We also made our own biodiesel using the chemical reaction shown above. Once we had our fuel, we constructed boats to race using our fuel. Addie and I's boat came in 1st! We were very excited to have our hard work pay off. I enjoyed the environmental aspect of this unit very much! Here are some links to better inform you of what biodiesel is and does:

Specific Heat Lab

In our first lab of the new unit, we tested the specific heat of copper and iron. Our group did copper. We tested the temperature of our tap water, then boiled our copper in a test tube in a hot water bath. The lab was short and somewhat interesting, but not my favorite. This lab did help me visualize what is happeneing in our practice problems and on tests.
