Unit 0 Flashcards
the group that DOES NOT receive the experimental treatment
Control Group
a factor in an experiment that remains constant
controlled variables
factors that are measured and respond to change
dependent variables
subjects that receive the changed conditions in the experiment
experimental group
a testable prediction
hypothesis
a factor that is being changed, one per experiment
independent variable
this will increase accuracy and validity of the data by lessening the effect of any outliers
large sample size
descriptive, non numerical information collected about the experiment
qualitative data
numerical information collected about the experiment
quantitative data
when an experiment is done several times to see if you get similar results each time
repeated trials
situation in which people acting individually and in their own interest use up commonly available but limited resources, creating disaster for the entire community. Ex: over fishing
tragedy of the commons
a prediction that there is no difference between groups or conditions, or a statement or an idea that can be falsified, or proved wrong. Ex: there is no line between smoking and developing cancer
null hypothesis
any process that increases a change to a system
positive feedback loop
process that decreases a change to a system
negative feedback loop
facts, data, physical, concrete testable information found first and then connected to large developed ideas (scientific method)
inductive reasoning
large ideas and “basic truths” are made first then facts and data (prove the big idea first)
deductive reasoning
a conclusion reached on the basis of evidence and reasoning (subjective)
inference
information obtained through the senses
observation
the decimal measuring system is based on the meter, liter, and gram as units of length, capacity, and weight or mass. King Henry Died by Drinking Chocolate Milk
metric system
different groups, no in-between or ranges. Ex: gender, color, ranks (pie charts, bar graph)
discrete data
standard measurement or ranges. Ex: length, amount, weight, time, temp (histogram, line graph, scatter plot)
continuous data
The ways in which an element—or compound such as water—moves between its various living and nonliving forms and locations in the biosphere
biogeochemical cycles
set up to look for evidence that supports its claims. Seeks confirmation. Ex: ancient aliens, moon landing hoax, astrology
pseudoscience
a summary based on evidence or facts
conclusion
the objective analysis and evaluation of an issue in order to form a judgment.
critical thinking
Dependent, Responding, Y-axis,
Manipulated, Independent, X-axis
MIX/DRY
A series of steps followed to solve problems including collecting data, formulating a hypothesis, testing the hypothesis, and stating conclusions.
(1) make observations, (2) research/ask Q’s, (3) hypothesis, (4) experiment, (5) gather/present data, (6) analyze data/draw conclusions, (7) submit for peer review
scientific method
The ability to keep in existence or maintain a sustainable ecosystem is one that can be maintained
sustainability
a group of parts that work together as a whole
system
a change from one form of energy to another
energy conversion
mistake
error
