Nature Of Science Flashcards
What begins all scientific inquiry?
All scientific inquiry begins with a question.
What do you need to know before starting an experiment?
You need to know what you are trying to find or prove.
What should you do after making an observation?
Do research using computers, books, and newspapers.
What should you know about the problem?
Know what other scientists say about the problem.
What is a hypothesis?
A hypothesis is an educated guess about what you think the outcome of the experiment should be.
Does a hypothesis have to be correct?
No, it does not have to be correct in the end.
What is involved in designing an experiment?
Develop and follow a procedure, choose your variables, and include a detailed material list.
What must the outcome of an experiment be?
The outcome must be measurable (quantifiable).
What is an independent variable?
An independent variable is what you are changing in an experiment.
What is a dependent variable?
A dependent variable is what you are measuring in an experiment, which is a result of altering your independent variable.
What should you do after performing the experiment?
Collect data and repeat the experiment multiple times.
How many times should you repeat an experiment for accuracy?
At least 3 times to ensure results are accurate.
What does repeating an experiment prove?
Repeating an experiment proves its reliability and validity.
What is reliability in an experiment?
Reliability means answers are consistent.
What is validity in an experiment?
Validity asks if your experiment shows what it should.
What is replication in scientific research?
Replication means the experiment can be done by others and shows confirmation of ideas and theories.
What are ban graphs used for?
Ban graphs are used to show comparisons between multiple items.
What are pie graphs used for?
Pie graphs are used to compare the parts of a whole.
What do line graphs show?
Line graphs show the relationship between variables.
