Science A body of knowledge and the process for building that knowledge of the natural world.
Based on inquiry that develops explanations and is rooted in unbiased observations and experiments
Theory An explanation of a natural phenomenon supported
by many observations and experiments
Scientist consider an idea a theory when enough evidence from many related investigations supports an idea
Most highly regarded theories in biology that are supported by countless observations and investigations, have extensive supporting evidence Example: Cell Theory
Organisms are made up of one or more cells, basic units of life, and cells come from preexisting cells
Scientific Law
Describes relationships under certain conditions in nature
Example: Law of Conservation of Matter
Indicates that before and after a change the same amount of matter exists
Does not explain why, just says that it does happen
Science Makes Observations and Draws Conclusions
Observations lead to questions
Investigations and experiments help to draw conclusions
Science Expands Knowledge
Research that results in a constant reevaluation of what is known
Reevaluation often leads to new knowledge that scientists then evaluate
Search for new knowledge is the driving force that moves science forward
What is Pseudoscience?Pseudo – meaning false
Areas of study that try to imitate science, often driven by cultural or commercial goals
Examples: Astrology, horoscopes, psychic reading, tarot card reading, palmistry, science fiction, magical medical cures, etc.
Not science based explanations
Bias claims that are a mixture of factand opinion
Claims that can not be tested
Not based on scientific research
Do not look to extend knowledge base
Science Challenges Accepted Theories
Scientists debate one another’s ideas
Discuss new developments and findings
Disagreements lead to further research
Your ViewsWhat do you think should
happen when investigations begin to show data and observations that do not agree with current scientific understandings?
Science Questions Results
Inconsistencies lead to additional investigations
Scientist find interest when observations and data are not consistent with current scientific understanding
Science Tests Claims Standard experimental procedures
Based on unbiased investigations and carefully controlled experimentation scientists make claims and draw conclusions based on a large amount of data and observations
Use of data to test and support claims
Data is analyzed before any conclusions are drawn
Scientists Undergo Peer Review
Peer review is a process by which the procedures and results of an experiment are evaluated by other scientist in the same field
Gives credibility and prevents false information
Compare and contrast their work - how new information is stumbled upon sometimes
Importance of Scientific Literacy
Science is in everyday life
Vast amount of information in print, online and on television
A scientifically literate individual can be an educated consumer who can participate in discussions about important issues and support policies that reflect their views.
Ethics – a set of moral principles or values that guide society
