What is a hypothesis?

• A theory
• An educated guess based on information that uses the words "if" and "then"
• What is changed in an experiment
• The first step in the Scientific Process

The scientific method is used best for...

• Solving problems
• Making an observation
• Developing new plants
• Growing new cities

A good testable question and a good hypothesis must be..

• Approved by the National Science Committee
• Based on prior knowledge
• Written in present tense
• Testable & measurable (independent & dependent variables)

The first step in the scientific method is to

• Write a testable question
• Make a hypothesis
• Go as someone for help
• Write the results

Which step from the Scientific Method is missing:
Testable question
Hypothesis
Experiment
Conclusion

• Gather materials
• Write down steps
• Results
• Run tests

How do you write a good conclusion?

• Make a graph
• Compare your results with others
• Restate the hypothesis; tell if data supports hypothesis
• Share results through tables and data

What is a dependent variable?

• The one change of an experiment
• What is measured in an experiment
• Things that must stay the same

What is a constant variable?

• The one change of an experiment
• What is measured in an experiment
• Things that must stay the same

What is an independent variable?

• The one change of an experiment
• What is measured in an experiment
• Things that must stay the same

Which step of the scientific method tells what happened and includes the averages of data collected in the experiment?

• Hypothesis
• Conclusion
• Experiment
• Results
