Scientific Behavior Flashcards
Material safety data sheets
A standardized information sheet for a substance; includes information about health risks, safe disposal and clean up of spills, and environmental risks
Accommodation
Occurs when existing schemas cannot be applied to new objects or situations, and must therefore be adapted and revised
Conclusion
A summary of the results of an experiment; states whether the initial hypothesis was rejected or supported
Hypothesis
And informed prediction (made based on previous observations) for a phenomenon. Should be testable
Precision
A set of different values which are close to one another
The Metric System
A standard system a measurement based on Powers a 10.
Experimental Group
A group of specimens in an experiment to which a change is made; receives experimental treatment
Line Graph
A visual representation of data which shows change over time or in response to a manipulated variable
Single-Variable Research
Type of nonexperimental investigation in which the researcher and makes observations before and after the application of a treatment or question
Organization
Student store new information and relate it to what they already know and understand about the world
Charles Darwin
An English naturalist who developed the idea of natural selection in theory of evolution these ideas were published in the book On the Origin of Species
Scientific Theory
A proposed exclamation for a phenomenon which may not be testable (Darwin’s Theory of Evolution)
Inquiry-Based Activities
Activities and allow students to participate in the scientific method with little guidance from the teacher
Feedback Loop
A series of experiments in which the results lwad to more possible hypotheses and subsequently more testing
Stem-and-Leaf Plot / Stemplot
A plot that splits each data values into a “leaf” (usually the last digit) and a “stem” (the other digits). Stemplots are used for smaller sets of quantitative data you can easily identify outliers, data clusters, or gaps on the stemplot.
Meters (m)
the unit for ditance in the metric system
Margin of Error
Deviation or variation of the value from the correct or expected value to allow for error and equipment or calculations
Guiding Questions
Quetions that lead to a deeper understaing by arousing curiosity and interest
Histogram
A visual representation of data which compares frequencies of different numeral intervals
Dot Plot
A graph that uses docs to show the frequency counts of a group of data that plots are used for small sets of quantitative data. You can easily identify the mode, the shape or skew of the graph, and potential outliers on a dot plot.
Qualitative Data
Data which is described rather than measured
Waft
Wave the air toward the face. The safe way to smell a test tube
Grams (g)
The basic metric unit of mass
Non-Experimental Investigation
A research method in which conditions are not carefully controlled; the scientist may study and independent and/or dependent variable, but does not control the other factors in the investigation
