Oleic Acid Lab/ Niels Bohr model

Today, Wednesday, the hump day of the week, we started an experiment called the Oleic Acid Lab. If you need the lab you can find it here. We also went over some notes on Niels Bohr and his atomic model. He concluded from his experiments and the experiments of other scientists of the time that the electrons orbits around the nucleus in set orbits. If you are interested in learning more on Niels Bohr click here. He was influential throughout the 40s and 50s with his work on the Manhattan Project. Now on to the lab. The Oleic Lab had to do with Determining the width, mass, and length of an oleic molecule. Here are some pictures of the experiment.

This is an example of a good circle that most people got with the oleic acid.

This is...well...not such a good example. It just looks like someone spit in it. :(

Mr. Lieberman also went over the Rutherford Experiment with us. He told us how to calculate the are of the circles:

circle area = (# of dots inside the circle divided by # of dots total) x total area of the paper

That will give you the area of all six circles together, so don't forget to divide that by six. Then the are of the squares inside the circle follows the same equation except its the # of dots inside the square divided by the total # of dots inside the circles. Mr. Lieberman also told us that everyone should have at least one dot inside the square. If you don't have one inside the square, add one.

Homework is the Rutherford Experiment and the Oleic Acid Lab which are both due Friday

Thank you everyone. This is Conor signing out. Next scribe is Lauren C.
