Unit 1: Introduction to Biology
Biology is the study of life. While biologists have made great strides in discovering things on earth, there are still many new things to learn. The first fundamental questions are: What is Life? What does it mean to have life? These inquiries are essential to the discoveries that biologists find every day. With such a vast scope of information, biologists must organize these discoveries that will stand the test of time. In this unit, we introduce the major topics that biologists study and the theories they use and apply to their work.
Completing this unit should take you approximately 4 hours.
1.1: Introduction to Biological Inquiry
Science is knowing. Scientists search for knowledge through inquiry, which is a way of questioning and explaining phenomena that occur in nature. Let's begin by exploring how biologists and researchers use the scientific method in the scientific inquiry of life.
1.2: Biology Systems and Water
There are some core properties that are found in all living things. Since it is unreasonable to memorize every biological discovery, biologists focus on unifying themes that every discovery falls under. Earth, the only known biosphere, is made of 75 to 80 percent water. Since the properties of water are conducive to life on earth, scientists search for life when they discover the presence of water on other planets.
