Biology The Science of Biology Biology means the study of life.
2
Scientific Method: This involves making predictions, designing experiments (a series of observations to test predictions), making careful observations of that experiment, and interpreting those observations. This includes: Observations Hypothesis Experiment Theory http://www.google.com/imgres

Scientific Method: Observations: what our senses tell us: sight, sound, smell, taste, and touch. –We can use tools (like the microscope) to help us. –Do not confuse conclusions (assumptions based on observations) with observations. –Results in collecting data (recorded observations) Hypothesis: a possible explanation for a set of observations. –This serves as a prediction about the outcome of an experiment. http://www.google.com/imgres
4
Experiment: this is done to test a hypothesis. This focuses on a problem. –A variable is a factor that can change in an experiment (temperature, amount of time, size, etc). –There is usually only 1 variable in an experiment being tested at a time. This is called a control set-up (1 experimental variable). http://www.google.com/imgres
5
Theory: This is when many experiments have been performed over time and support a hypothesis. –A theory is a probable explanation that is supported by a lot of evidence and is generally accepted as true. Ex. Biogenesis, Cell Theory, Theory of Evolution, & Germ Theory. http://www.google.com/imgres
6
Compare Hypothesis & Theory: –H: “Mimicry protects nonpoisonous snakes from predators.” –T: “Adaptations such as mimicry evolve by Natural Selection.” Limitations of science: Supernatural forces
