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
