The Scientific Method
What is the difference between replication and repetition?
Replication: where other scientists repeat your experiment to see if they get similar results
Repetition: where YOU repeat your experiment more than once to see if YOU get the same results
What are the three types of graphs scientists use?
True or false: Theories cannot change. Their knowledge is set in stone.
FALSE

Data
What are the 6 steps of the scientific method?
