Final thoughts on Atomic Structure and Radioactivity

In this unit we learned about what happens to atoms over time. We learned about three different scientists who contributed to our knowledge of atoms, Dalton, JJ Thompson, and Ernest Rutherford. They all conducted different experiments that helped to understand how atoms work. We also discussed radioactive decay and how it affects the nucleus of the atom.

Half-Life and Forensic Archaeology Lab

Today we learned a new lesson about half-life. We had 567 squares and we flipped them 5 times until we could get them to "decay". This was honestly kind of annoying and took a long time with all of the counting and when you miss count it messes up the data. But it did help me to understand better how radioactive decay works.

Beanium Lab

I assumed by the name "Beanium" that it would have something to do beans. We used our newly learned skill of calculating mass to do this lab. Each bean was one isotope. We had to calculate the mass of each "isotope". This lab helped us learn and practice calculating average atomic mass.

Isotopes

Today we did a lab using beans to calculate atomic mass. Also we learned how to write an isotope in proper notation. I understand how to calculate the amount of subatomic particles. This was a new concept to me, but after taking notes and going over the lesson I understand this topic.

First things learned about Atomic Structure and Radioactivity

We first learned about different scientists and how they contributed to the atomic model. We learned how to calculate percentages. of certain elements. During the pre-test I was very confused but afterwards after the notes and lesson I understood the concepts.

First thoughts on Atomic Structure and Radiation

During the pretest I felt like I was back in kindergarten learning how to write letters for the first time, by that I mean I was clueless. This was a very difficult test for me. I have no idea what Beta or Alpha mean and I actually don't even know how any of this works.
