Scientific method
Come up with reliable answers and solutions
Goals of following scientific methods?
Independent variable: Whether or not there was a mouse Dependent variable: Elephant's reaction
Are elephant afraid of mice? Explain the independent and dependent variables.
Independent variable: The object tested Dependent variable: The angle the rig arm went up
Can a rock thrown from a lawn mower have the same force as a bullet shot from a gun? Explain the independent and dependent variables.
Independent variable: Dimples or not Dependent variable: amount of gas mileage
Does adding dimples to a car increase it's gas mileage? Explain the independent and dependent variables.
Gather and analyze data/results; summarize data and describe what results are illustrating (tables and graphs)
Fifth step of scientific method ?
1. Observations; five senses and identify problem to be investigated
First Step of the Scientific Method?
Test the hypothesis; design a controlled experiment (test ONE variable at a time)
Fourth step of scientific method?
Insight solutions into problem investigated
Gains on using scientific method?
Independent variable: The speed they moved Dependent variable: mass of the rain
Is it worth running in the rain? Explain the independent and dependent variables.
2. Ask a question; background research and focuses purpose of investigation
Second step of the scientific method?
Communicate results; sharing what u learned with others with published findings, videos, articles, conferences, in person
Seventh step of the scientific method?
Draw conclusions; state if results supported by hypothesis and if supported= further investigation not supported= repeat investigation to find errors, ask new questions and form new hypothesis
Sixth step of the scientific method?
Form a hypothesis; possible explanation or answer to a question that CAN be tested
Third step of the scientific method?
Dependent variable; measured during an experiment, DATA
What is an dependent variable?
Independent variable; The one that is changed by scientists, difference between control and experiment groups
What is an independent variable?
Series of steps to answer questions and solve problems
What is it?
What results of experiment are compared to, the do-nothing or baseline group
What is the control group
