Yesterday on a beautiful Tuesday morning, I walked into first hour chemistry ready and prepped to take the pre-lab question test. I had studied all night the lab procedure and post lab questions. I was fully prepared for this quiz! So once the bell rang, Mrs. Frankenburg asked the class to pick a number between 1-5. The class agreed on number 3. After that the pre-lab question came up on the smart board, for it was about finding the average atomic mass of three isotopes. I was relieved to be able to know exactly how to do this type of problem. Once I got the answer correct, I was able to go into the back of the room to conduct the experiment with my lab partner. Mrs. Frankenburg told us to pick the bag with the smallest amount of beans, for it helped so much in the long run with conducting the lab quicker. So the first thing we did was separate the beans by their color and counted each of them, for later we took the masses of all the different types of beans using a scale. We then figured out the average atomic masses of the beans. In all, the experiment was actually pretty fun!!!! Plus my lab partner and I kept flaunting about how cute the mini red solo cups were!
The pictures were a nice supplement, rather than just explaining the lab in words. It helped further understand the subject of your post.
