A hypothesis that continues to be supported by evidence may become a(n)

• observation

• inference

• process

• theory

During an experiment, which factors are observed and measured?

• dependent variables

• independent variables

• constants

• hypotheses

The step in the scientific method that is most related to making a prediction based on observations is

• forming a hypothesis

• testing a hypothesis

• drawing conclusions

• none of the above.

The variable that is manipulated/changed/tested by the scientist is the

• dependent variable

• independent variable

• control group

• hypothesis

Put the following steps of the scientific method in the proper order.

A.) State conclusion

B.) Record and analyze data

C.) Design and carry out experiment

D.) Identify the problem/Ask a question

E.) Formulate and state hypothesis

• A-B-C-D-E

• D-E-B-C-A

• D-E-C-B-A

• E-D-C-B-A

A series of steps used by scientists to solve a problem or answer a question. 

• scientific method
• recipe
• data collection

This variable in an experiment is the one being changed by the scientist. 

• dependent variable
• independent variable
• data
• control group

Testing a hypothesis often involves a(n):

• answer
• experiment
• problem
• safety check
