The History of Atoms

Several days ago I read about the history of atoms, and how they were discovered. J.J. Thomson was the first scientist to come up with the idea that atoms had both a negative and positive charge. His model consisted of a cloud of positive charge with tiny particles of negative charge are randomly despersed inside as show in this model known as the "Plum-Pudding Model."

Later it was Ernest Rutherford who discovered that the center of every atom contained a positive charge not the entire atom itself. He did this by firing alpha radiation at gold foil and finding that some were reflected off when they hit. This diagram helped me visualize how he figured it out.

Beanium Lab

Earlier this week, me and a partner used beans as a way to act like an element, there were 4 different colors of beans and we took the total mass of each color acting as if the color group of each bean represented isotopes of an element. The reason we did this was in order to help reinforce our understanding and ability to calculate average mass and percent abundance of each isotope, and the over all average mass of all the isotopes which would represent atomic weight.

The lab itself isn't very exciting, but it does help anyone who is looking for practice in calcualtion atomic weight, average mass, or percent abundance of an isotope(s), and if you find yourself needing extra practice I have a video linked below to a video on calculating percent abundance. Using that formula you will end up with atomic weight.

The set-up doesn't require much either, the only equipment we used was a scale, samples of beanium, small cups, and a calculator.

Frontier Chemistry Project

Over the last month I have been constructing this blog and completing a project at the same time. This blog was structured in a way that you would be able to find certain plants to cure certain maladies, but I also have a page dedicated to plants I know from personal encounter, and with the names of each plant I have their habitat and what they cure. All of the plants I have from personal encounter are found in Missouri. The maladies have plants to cure them, but on each page it doesn't say what all the plant heals, but you will see that some plants cure more than one injury. I used online resources and books to find the information needed to complete the assignment, and on each page there are links to the sources I used. On my next time doing a project I will make sure to find the most efficient way to complete the project because the way i did this one consumed more time than what it needed.

Reflection of Frontier Chemistry Essay

Last week I wrote a semi-essay about different plants that can help heal certain maladies. I used pages that i created and posted on this blog to solve different situations there were presented. The injuries that were given to me were an ax wound, and tick bites. I used mostly plants from personal encounter to find out which plants could help mend the wounds. I hope I did well, I completed all of the requirements, so I presume that I did fine. I have trust in my blog, and the resources I used to create it, and the cool part is that I only used plants that I found from personal encounter, which means if a bear actually did attack me I would be able to use herbs to heal it. The difficult part of the essay was the time frame given, we only got one class time to complete it, and if I had an assignment like this again I would probably use my time more wisely since I barely finished it.
