• a proven statement
• a conclusive statement
• a definite answer to a possible problem

The purpose of a controlled experiment is to allow a scientist to isolate and test-

• a single variable
• several variables
• many data
• a conclusion

The variable that is measured in the experiment is-

• the dependent variable
• the independent variable
• the control variable
• the hypothetical variable

A hypothesis is a statement that-

• can be tested
• is almost always true
• is almost always false
• is the same as a theory

A theory-

• may be revised based on new information or scientific data
• is always true
• is the same as hypothesis
• is a question to be answered

Should experiments be repeated over and over to see if the results are the same each time?

• yes
• no
