Almost every dog owner has experienced their dog giving them a big, slobbery lick on the face or hand. Some people love it, others hate it, but it's a nearly universal part of dog ownership. But why does man's best friend seem to enjoy licking humans so much?

Everyone’s favorite Mythbuster, Adam Savage, once said: “the difference between screwing around and science is writing it down!” So true, Adam, so true. As long as you record your observations, you’re a scientist. Scientists gather knowledge, make observations, write them down, and test their theories. This process is known as the scientific method.

There are three main branches of science: physics, chemistry, and biology. These sciences combine with other fields to make specializations. For example, if you wanted to be a doctor, you would study human biology and organic chemistry. If you wanted to be an astronomer, you would study astronomy and astrophysics.

Those that study the sciences will tell you how closely related math, science, and engineering are. The acronym, STEM (Science, Technology, Engineering, and Mathematics), refers to the close relationship between these fields. People in STEM industries help to shape our understanding of the world. Without STEM, our quality of life would be poor. Not only would we be without cell phones and computers, but we also wouldn’t have vaccines and surgery. At this point in history, it is hard to imagine what our lives would look like without it.
