Repetition Vs. Replication

Replication is when one scientist

• copies another scientist's experiment.

• laughs at another scientist's experiment.

• repeats their own experiment several times.

• clones another scientist.

Repetition is when one scientist

• copies another scientist's experiment.

• bumps into another scientists.

• repeats their own experiment several times.

• clones a T. rex.

A basic principle for scientific research is that the experiment must be able to be replicated. What happens when an experiment is replicated?

• A scientist publisher accepts the experimental results for printing.

• No one in the scientific community agrees with the methods or results.

• Other scientists perform the same experiment and get comparable results

• The scientific researcher preforms the experiment many times and gets the same results.

Scientists repeat scientific studies to validate results

• True

• False

Repeat and Replicate, are basically the same thing.

• True

• False

Scientists have MANY trials so their results are 

• countable
• graphable
• reliable
• hard to understand

When a another scientist does someone's experiment to see if the results are valid?

• repetition
• replication
• experimental method
• controlled variable

Scientists frequently repeat the experiments of others scientists. Why is this important in science?

• Scientists often ask each other for help in performing experiments.
• Replication of experiments helps to confirm and verify results.
• Scientists frequently perform other scientists’ experiments in order to practice their technique.
• Repeating experiments is an effective way to make sure a laboratory is in optimal condition.

Caira reads in a science journal that replication and repetiton are so important, but she did not understand the  difference between them. Which of the following best explains the two terms?

• Repetition is when a scientist repeats an experiment; replication is when a scientist conducts an experiment on genetic material.
• Repetition is when a scientist does the same experiment a number of times; replication is when other scientists reproduce a scientist’s experiment.
• Repetition is when a scientist publishes in more than one scientific periodical; replication is when another scientist reproduces another scientist’s results.
• Repetition is when a scientist commits an error in an experiment the first time and must repeat it; replication is when a scientist repeats an experiment to make sure it is valid.

Dr. Smith has been reading about another scientist’s research in a physics journal. He plans to do these experiments himself and see if he gets the same result.
