Vocab
True or False: A hypothesis is a random guess, and no research prior to forming it should be done.
False- hypothesis are educated, and require prior research.
True or false: models must be testable, changeable, and based on evidence.
True
Morty is doing an experiment to see which type of gasoline will make his spaceship fly the farthest. What is the independent variable in this experiment?
The type of gasolines in the spaceship.
Which comes first, making an observation or drawing a conclusion?
Making an observation
Qualitative Data
When someone else does your experiment to see if they get the same results.
Morty is doing an experiment to see which type of gasoline will make his spaceship fly the farthest. What is the dependent variable in this experiment?
How far the spaceship will fly
Which comes last, forming a hypothesis or asking a question (or stating a problem)?
Forming the hypothesis
When you do the same experiment multiple times to make sure your results are consistent.
Repetition
Well tested, highly-reliable EXPLANATIONS of natural phenomena.
Scientific Theory
The variable that is measured in the experiment; this changes DEPENDENT upon the initial change you made.
Dependent Variable
Which comes first, gathering data or analyzing results?
Gathering data
What is used as the example or comparison for the data collected in the experiment; not changing plants growing in normal dirt when examining how fertilizers might improve growth.
The variable that you change initially is called the....
Independent variable
Why is it important to set controls within an experiment?
To ensure only one factor changes within your experiment. Otherwise, results will be skewed.
Why is it important to share results of an experiment?
Without sharing results, scientific progress won't be made.
Data that includes numerical values or quantities.
Quantitative Data
A STATEMENT or DESCRIPTION of an observed natural phenomena
Morty is doing an experiment to see which type of gasoline will make his spaceship fly the farthest. What are some variables Morty should keep constant to have reliable results?
The area he is flying, the type of spaceship he is driving, the time of day (space traffic)
What is the final step in the scientific method?
Sharing results.
