Test Review
Chapter 1 Biology
Scientific Method
• What is the sequence after the problem has been stated?– Careful observations– Statement of IF….Then Hypothesis– Creating Experiment– Test hypothesis– Collect and organize data– Draw conclusions– Possibly revise hypothesis and retest
Hypotheses
• How are they formed? – Prior knowledge– Logical inferences– Imaginative guesses
Controlled Experiment
• Know it is to isolate and test a single variable.
Theory
• Well tested explanation using a broad range of observations.
Living Characteristics
• Growth • Use of energy • Reproduction• Basic unit(s) called a cell• Genetic blueprint• Homeostasis• Evolve• Respond to environment
