Forensic Archeology Lab

This lab reminded me a lot about what we recently did in Human body systems. In this lab we had to use radioactive dating to determine the age of a skeleton. In HBS we had to find out who the person is using the information given. I enjoyed the concept of the lab but didn't enjoy cutting the pieces of the paper out. It was very tedious. Using the formula and information given we were able to determine how old the bones approximately are and who it was.\

Unit Test

We had our Unit test over Atomic structure and Radioactivity. There weren't many difficult questions but there were some that were time consuming. I knew how to answer every question. If i get something wrong then it was because I didn't work it out correctly. I feel like I got a very good grade on this test,. This unit was pretty interesting but it was harder than the last unit.

Beanium Lab

We recently did the beanium lab. It is an activity to help understand isotopes. Isotopes are elements with same proton count but different neutron count. There were different types of beans and each bean had a different mass. These beans represented isotopes. We used these isotope masses to find out the average atomic mass of the beans. This is a way to help us understand how to do this with different elements and their isotopes.

Atomic Structure and Radioactivity Weekly Quiz

I was well prepared for this quiz. This quiz was over the atomic structure. I understood how to find mass when number of protons and neutrons are given. I also knew who discovered what about the atom. Dalton discovered that the atom was like a solid ball. J.J Thompson discovered that there are electrons in the atom. Rutherford discovered that there is a nucleus in the center of an atom. I also learned how to find the average atomic mass of a substance.

Lab

I n class we recently did a lab. This lab we did was a guess the shape inside a little circular can. There was a ball inside and we had to feel around with the ball to try and guess the shape. It was fairly hard but I was able to figure out a couple. Most people didn't get many and overall is was an easy lab to do but guessing was a little difficult.

Pre-Test

We took a pre-test on Atomic theory and radioactivity. I did not understand  anything in the test and probably didn't get over a 20 percent. The only thing I sort of knew was half life. I probably got those right.  I hope I can learn everything that was on that test and ace the unit test and any quizzes.
