Mr. McNeice wanted to know if different types of music affected people's heart rates, so he played different music and checked their pulses.  What is the dependent variable?

• type of music
• heart rate
• how long they listend to music
• Mr. McNeice

Research Question: Does the type of gasoline put in a car effect how fast the car can drive. What is the independent variable?

• Type of gasoline
• which car the gas is put into
• how fast the car can drive
• how much gas is put into the car

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.

In 1897, Joseph Thomson discovered that atoms contained electrons.  He proposed a change in the atomic theory of that time, and the theory was modified because of his discovery.  Since Thomson’s discovery, atomic theory has been further modified.  What is the best explanation for why scientific theories are modified?

• Theories more than ten years old are usually out of date.
• Scientists want to prove that the work of other scientists is wrong.
• New evidence that supports a revision prompts scientists to modify earlier theories.
• So much information is available today that it is harder to focus research and disprove theories.
