John Dalton’s Atomic Theory Essay

John Dalton was an English chemist, physicist, and meteorologist. Dalton was born in 1766. He is best known for his work in color blindness, and of course, his Atomic Theory. His theory gave us an idea about what the universe is really made up of, and he paved the way for many more important scientific discoveries after he died in 1844.
His theory was simple: He stated that all matter is made of atoms. He based his theory on two laws: the law of conservation of mass and the law of constant composition. The law of conservation of mass says that matter is not created or destroyed in a closed system. If a chemical reaction is preformed, the amount of each element we had has to be the same before and after the reaction. In other words, if we combine…

One skill that he used was Asking Questions and Defining Problems. Without asking questions, he never would have had the motivation to create his theory. He also most likely defined the problems in his theory while striving to perfect it. He also used Planning and Carrying Out and Investigation, and Analyzing and Interpreting Data. When he was studying different elements, he was planning and carrying out investigations to learn more about the atoms that he proposed where there. While he was taking his findings and looking over them, he was analyzing and interpreting his data.
Dalton used the NGSS skills and applied them to the Marshall Middle essential question: “which is worse, failing or never trying? “ He used his skills when trying to perfect his theory. He hit a lot of bumps in the road and probably wanted to quit multiple times. The fact that he didn’t connects to our essential question. He decided that never trying was worse than failing, so he developed and shared his theory although he risked his reputation.
Although Dalton did not directly work with anybody when developing his atomic theory, he used information from other scientists before him. He based his theory off of work that other scientists had done, which helped him improve it. This is a type of communication, although indirect. All scientists share their ideas with others, whether they tell them or somebody studies what they have…
