Biology Basic Ideas
The Goal of Science • To understand the world around us.
The Scientific Method • Process (Way of Thinking) • Observe and state a problem • Form a hypothesis • Experiment • Record and analyze data • Form a conclusion • Repeat
Experimenting • Variable • Control Setup • Experimental Setup
Hypothesis-Theory • A hypothesis becomes a theory when it can be proven over and again.
Metric System • Based on multiples of 10. • Also known as SI. • Length-meter • Volume-liter,cc or cm3 or mL • Mass and Weight-kg • Temperature-Celsius scale
Facts and Truth • Constantly Changing • Science is a process • Some scientists can misapply data for their own prejudices • You need to know about science to make sure people don’t try to mislead you
Characteristics of Living Things • Made up of one or more cells- unicellular and multicellular • Reproduce- sexual and asexual • Grow and Develop • Obtain and Use Energy- anabolism, catabolism, metabolism • Respond to their environment-stimuli, irritability, homeostasis
What is Biology? • The study of living things • Study Prefixes and Suffixes
