Questions for 2nd Quarter Chemistry Project

Click Here for the Questions for my Chemistry Project. They were taken from a passage in Jean Baptiste Perrin's "Les Atomes" which was translated from French. Enjoy!

Essential Question # 1

1. How do scientists model the structure of matter?
Scientists model the structure  of an atom using the electron cloud model. It was developed by Erwin Schrödinger after he took Neils Bohr's discovery and took it to a whole new level. Bohr's discovery was that he found quantum, energy an electron releases when returning to its ground state. Schrödinger took Bohr's ideas and found that electrons do in fact go in orbitals, but in different angles and shapes. Schrödinger 's model is the most exact and current model we have to use in the present day. It helps us to understand the structure of matter the best.

Flame Test Lab: Q # 4

This lab was a lot of fun to do. I learned that certain metal salts make a certain color flame when ignited. This can be useful when unknown chemicals are found and its necessary to know what kind they are. By igniting them, you can find out what they are by just knowing what color the chemical emits. If you can find a match then you can know if the chemical is harmful or not. This is important to know so the chemical doesn't contaminate a water supply. I found that some have to be viewed under a Co glass in order to see the correct flame. This is important because a substance could be viewed incorrectly if not using the correct identifiers. Overall this was a good and fun lab to do.

Essentail Questions Chapters 1, 2, and 3

1. How do scientists measure quantities?
Scientists measure quantities by using The Metric System or The English System.
2. How can error or uncertainty in measurements be
    estimated?
Error or uncertainty can be measured by first recording the digits that you know. You always have one estimated number in each measurement you make making all your measurements uncertain and estimated in some sort.

Summer Highlight

A lot of interesting events happened this summer. Out of all of them, my favorite was when I went to Edinboro University in Pennsylvania for a basketball camp. It was a lot of fun and I met a lot of new friends. I even got a new nickname! It was Zamboni. A girl couldn't pronounce my last name so she thought of another "Z" name to give me and then Zamboni stuck! I miss the people a lot, but we keep in touch. The only bad part of camp was leaving them all behind! I'm glad I was able to have this experience this summer and I can't wait to go back next year.
