• Define science• List 5 different branches of science
Science is a process of observing, studying, and thinking about things in your world to gain knowledge.
• Biology-living things• Chemistry-atoms/molecules• Physics-motion• Astronomy-space• Zoology-animals• Botany-plants• Microbiology-microorganisms• Genetics-genes/heredity• Ecology-environment• Paleontology-fossils• Psychology-brain/behavior• Gastroenterology-digestive system• Neurology-nervous system
• Anatomy-body parts• Physiology-how body parts work• Ichthyology-fish• Entomology-insects• Ornithology-birds• Geology-earth• Climatology-climate• Meteorology-weather• Oceanography-oceans• Pathology-diseases• Virology-viruses• Hydrology-water
movement/distribution
Through what method do scientists try to solve problems?
• Scientific method– Definition: a series of steps used to solve a
problem.
The Scientific Method
• Identify the problem• Gathering information• Develop hypothesis• Test the hypothesis• Analyze the results• Draw conclusions
The Scientific Method
• Identifying a problem• Purpose?• Enhance understanding
• Gathering Information• Research• Indicate if and where controversy exists
• Make a hypothesis• Definition- an educated guess
The Scientific Method
• Working with a partner brainstorm several ideas for an experiment.
• Come up with a testable hypothesis.
The Scientific Method
• Test the hypothesis• Experimentation
– Procedures• Choose variables
• Dependent variable—Change in response to other variables; what is being tested
• Independent variable—influences the dependent variable; variable that changes
• Control—independent variable is held constant; unchanged
– Materials gathered
• Reproducibility and repeatability?
The Scientific Method
• Analyze the Results• What occurred?
– Observations– Measurements– Graphs – Charts
• Draw conclusions• Answers the question• Is the hypothesis correct
– Theory—proven hypothesis
• Problems/Changes in the experiment
• Using the article “Is Txting 2 Much Bad 4 U,” brainstorm with a partner about a possible experimental design.
• Be sure to come up with a possible Problem statement, hypothesis, and experimental design.
