THE WORLD OF CHEMISTRY
I learned a lot about chemistry. Chemistry is the branch of science that deals with the identification of the substances of which matter is composed. I learned about the different sugars like glucose, fructose and the differences between them. I also learned how to balance electrons in elements in compounds. Although I will not use this in the future, it surely sharpened my skills by making me think harder.

To be honest, chemistry is my least favorite branch of science. To me it is too complicated, which is why I don't always get it once it is taught the first time. Ironically, the current quarter focuses on it. Being a student left with no choice, I learned to accept the lessons in which I am equipped to learn; regardless if I like it or not. Besides, I actually learned a lot this quarter regarding the said branch of science.
Gas laws were one of the first few lessons in the 3rd quarter. This is equipped with several equations that involves volume, pressure, temperature, and moles. These 8 laws have different formulas that may seem confusing most of the time. These also show the direct and inverse relationships between quantities. It is with this that I know that Boyle, Charles, Gay-Lussac, and Avogadro made great impacts in the field of science with the discovery of their respective laws.
Several lessons were also discussed that actually got me frazzled and confused. From carbohydrates--the most abundant class of organic compounds, lipids--insoluble nutrients, and chemical reactions, it is actually very hard to understand. Although I do understand chemical reactions as it was my topic for my infographic, the subtopics related to it are quite complicated. But I do know giving it the attention it really needs, I will be able to master the topics.
The world of chemistry, overall, is very diverse. I learned a lot. It contains many simple and hard concepts. Though it often gives me a headache, I can definitely say that chemistry was such a pleasure to learn about. Well, without it, where would we be?

Actually, I didn't want to study chemistry. But since it's in my favorite subject, I had to study what it is all about. I learned that chemistry is kind of part of our lives. The air we breathe, everything we see in this world. Everything, even our very own DNA. So I guess, without chemistry, we won't be having this new kinds of stuff like medicines or something we call the nuclear bomb.
Chemistry has different branches. Theoretical Chemistry, it's just or theoretical things. Nuclear Chemistry, about the properties of nuclear reaction and my favorite. Reminds me of Fallout 4, you know. Neurochemistry, like Biochemistry but specialized in neurochemicals. Biochemistry, study of chemicals and reaction that occur in living organisms.

What I learned on chemistry during 3rd quarter is about the laws that Boyle, Charles, Gay-Lussac, and Avogadro have made. Also about the replication of DNA. I learned about this during making my infographics Some of the topics is quite hard to understand like balancing chemical equation. The trial and error part is fun but it takes a lot of time to answer 1 problem.
I also learned about Carbohydrates, organic compounds, lipids, and nutrients. 3rd quarter is quite fun even if it is hard. The collision theory is quite fun to learn also.

I had learned a lot from the topics taught and explained this quarter ( 3rd ). Starting with the different kinds of gas laws and up to the chemical reactions and equations. In a nutshell, below are the main points I have understood from each lesson: ( lesson 16) As known by many, gas is a state of matter and like solid and liquid, gases also have properties. To cite a few, gases have much lower densities than liquids and solids but they have no definite shape nor volume and they can be compressed readily. Gases also have laws — namely Graham's law of effusion; Boyle's law, Charles law, Gay-Lussac's law, Dalton's law and the ideal gas law. Some of them deals with the volume, pressure and temperature. It varies depending on the law.
The next lesson that was discussed is about carbohydrates in general. (lesson 17 ) Carbohydrates refer to the nutrients produced by plants and consist of carbon, oxygen and hydrogen — it undergoes condensation reactions and hydrolysis reactions. Monosaccharides are the simplest carbohydrates.
Lipids are a group of biomolecules that have a high percentage of C and H content. Fatty acids consist of a long hydrophobic nonpolar hydrocarbon and a hydrophilic polar carboxylic acid functional group. Carbohydrates and lipid contents of food proteins can be located at the nutritional value chart in the product labels.
( lesson 18 ) Proteins on the other hand are large biomolecules that consist of long chains of building block molecules called amino acids. They are part of different bodily functions including; catalysis, protection, movement, transport and regulation. Amino acids are organic compounds made up of a carboxyl group. The protein structure has four levels namely the primary, secondary, tertiary and quaternary. Nucleic acids are made up of a long chain of nucleotides — breaking it down, nucleotides are composed of three parts ( a ) nitrogen-containing base, ( b ) sugar and ( c ) phosphate group.
Lesson 19 basically consists of chemical transformations. A chemical equation consists of symbols and formulas that represent a chemical reaction. It is an indication that the physical state of the reactants and products in the reaction. The equation is said to be balanced when the numbers of each element are the same in both sides of the equation. There are four different types of reactions that can be represented by chemical equations:
i.) Combination reaction A + B -> AB
ii.) Decomposition reaction AB -> A + B
iii.) Single replacement reaction AB + X -> AX + B
iv.) Double replacement action AX + BY -> AY + BX
