Last Meal Party

In chemistry today everyone brought in a dish from their last meal conversion project. The project was to help us understand how to convert measurements from one unit to another. The project was fun and helpful in reinforcing what we learned over the unit.

End of Matter and Measurement

Today we took the final quiz on matter and measurement. There were a lot of density and conversion questions. The questions were easy to make a mistake on and required a lot of attention to make sure they were completed correctly.

Matter and Measurement Quiz

I believe that the quiz was rather easy. There were just a few questions I was not sure on, such as the significant figure problems.

Mole Day

To celebrate mole day our chemistry class had a party. We also all made a mole with a theme. I think the moles were very creative and one of my favorites was the mole dancer.

Pre-Test Thoughts

I believe that the pre-test was semi-difficult. I recognized hetero- as being different and homo- as being the same from biology last year. Although I did recognize these words I did not know which zeros were considered significant. Overall I did not know much on the test.
