|
Scientific Experiments
|
Constant Factor that remains unchanged
|
|
Independent Variable You control; adjustable
|
|
Dependent Variable Stimulus that we don't change but is changed by other variables
|
|
Control Part of experiment that remains unchanged to compare the results
|
|
Scientific Method Series of steps used to investigate a scientific question; steps can be skipped or repeated
|
Scientific Method
|
State the Problem Ask a question about the problem to learn about/solve
|
|
Background Research Textbooks, internet, scientific journals, encyclopedias, newspapers
|
|
Formulate a Hypothesis Suggest a solution to the problem
|
|
Design an experiment Organized process designed to test hypothesis. List all materials and procedure in correct step-by-step order
|
|
Collect + Organize Data Detailed charts, graphs, models, drawings
|
|
Analyze Data Study data carefully
|
|
Draw a Conclusion Is the hypothesis right or wrong? Restate it. Based on analysis of data.
