Steps to Systematic Method Flashcards
the first step; includes observations based on senses or tools that usually raise questions
Make an observation
the second step; this is where you form something that tries to explain your observation or answer your question
Form a hypothesis
tries to predict the outcome of the experiment before it is even done; an educated guess; “if… then”
hypothesis
the third step
Test the hypothesis
experiment that tests only one factor at a time
controlled experiment
group that is compared with an experimental group, wherein variables are not changed
control group
factor that changes in a controlled experiment; are changed in the experimental group and the factor that is tested
variable
variable being manipulated or varied
independent variable
variable being tested or measured; responds to the changed independent variable
dependent variable
the fourth step; data is organized in tables, charts, and graphs so it can be analyzed easily
Collect, organize, and analyze data
recorded observations or measurements (qualitative = description, quantitative = number data)
data
the fifth step; scientists decide whether the results of the experiment support a hypothesis or not (no experiment is a failure)
Draw conclusions
the fifth and last step; scientists decide whether the results of the experiment support a hypothesis or not (no experiment is a failure)
Draw conclusions
the sixth and last step; results must be communicated in the form of a written paper or presentation to help people see if their results are repeatable
Communicate the results
the sixth and last step; results must be communicated in the form of a written paper or presentation to help people see if their results are repeatable
Communicate the results
explanations for some phenomena based on observation, experimentation, and reasoning
Theories
summaries of many experimental results and observations
Laws
application of science to meet the needs of society, which may lead to new scientific discoveries
Technology
