Unit 1 Chapter 1 Lesson
The Science of Biology
What is science?
One ancient evening, lost in the mists of time, someone looked into the sky and wondered for the first time: What are those lights? Where did plants and animals come from? How did I come to be to? Since Then, Humans have tried to answer those questions. At first, the answers our ancestors came up with involved tales of magic or legends like the one that accounted for the eye-like markings on the peacock's tail. Then Slowly, humans began to explore the natural world using a scientific approach.
What Science Is and Is Not
What does it mean to say that an approach to a problem is scientific? (Key) The goal of science is to investigate and understand the natural world, to explain events in the natural world, and to use those explanations to make useful predictions. Science has several feature that make it different from other human endeavors. First, science deals only with the natural world. Second, scientists collect and organize information in a careful, orderly way looking for patterns and connections between events. Third, scientist propose explanations that can be tested by examining evidence. In other words, Science is an organized way of using evidence to learn about the natural world. The Word science also refers to the body of knowledge that scientists have built up after years of using this process.
Thinking Like a Scientist
Suppose a car won't Start. Is the car out of gas? A glance at the fuel gauge tests that idea. Perhaps the battery is dead. An auto mechanic can use an instrument to test that idea. To figure out what is wrong with the car, people preform tests and observe the results of the tests. This familiar activity uses the approach scientists take in research. Scientific thinking usually begins with observation, the process of gathering information about events or processes in a careful orderly way. Observation generally involves using the senses, particularly sight and hearing. The information gathered from observations is called data.
