Chemistry can be broadly defined as the study of matter and the changes that it undergoes. In Chemistry there are several different branches including organic chemistry, inorganic chemistry, physical chemistry, analytical chemistry and biochemistry.

Alright, here in Chemistry class and you're wondering, what I'm I going to be learning? Well Chemistry is the study of matter and the change it undergoes but that's kind o broad. So Chemistry actually is brought into five different branches.

The first branch that we're going to talk about is organic Chemistry and organic Chemistry is anything dealing with carbon atoms. So anything bonding with carbon, and it has a whole branch of it. So we're dealing with plastics, dealing with pharmaceuticals, anything that falls under that will be falling under organic Chemistry and that's a whole other course on it's own.

Inorganic Chemistry is actually what you're going to be learning in class this year. Inorganic Chemistry is dealing with metals, anything non-carbon based. That's why they called inorganic. So dealing with metal, dealing with minerals, dealing with salts, dealing with solutions, those things are dealing with inorganic Chemistry, non-carbon based Chemistry.

Then it's been broken down further into physical Chemistry and physical Chemistry is where you bring in Physics and Chemistry together, talking about nuclear Chemistry, talking about different ways that they actually interact with other substances, you know physical Chemistry is a mixture of Physics and Chemistry together.

Then we have analytical Chemistry and analytical Chemistry is when you're analyzing different substances. So he has to analyzing them in all five areas. However, analytical Chemistry is focussed strictly on how do we analyze this? We're dealing with things like within the FDA, how to do measure percentages within solutions contamination, dealing with environmental things, things like that.

And Biochemistry is the last of the five branches and that's dealing with a lot of medicinal things. Dealing with metabolism, fragmentation, how Chemistry deals with Biology so this is how Chemistry is a sister with another science of Biology.

So Chemistry is actually what we have in college, it's like the sister, the middle child of all the three sciences. We have Biology, and how Chemistry deals with that, and we have Physics and how Chemistry deals with that and Chemistry actually encompasses all the Sciences into one.
