Scientific Method

Scientific Method and Potential and Kinetic Energy

Review Day 1

Remember the Scientific Method is a process.

• 1. Observation/Question

• 2. Research

• 3. Hypothesis - Predict the outcome (educated guess)

• 4. Expreiment (Develop a Procedure)

• 5. Collect Data

• 6. Analyze Data

• 7. Conclusion

Variables in Scientific Experiments

• Controlled Variable - elements of a experiment that stay the same

• Independent Variable - the one variable that changes for an experiment

• Depentent variable - a measurable variable that will change based on the independent variable

• ONLY ONE VARIABLE SHOULD CHANGE IN ANY WELL DESIGNED EXPERIMENT!

Question: How does the weight of paper change how far a paper airplane flies?

• Independent variable - paper weight

• Dependent variable - distance the airplane flies

• controlled variables - airplane design, type of throw, where thrown, wind...

Multiple Choice

Question: How does the design of paper change how far a paper airplane flies?

What is the independent variable?

• airplane design

• distance the airplane flies

• type of paper

• type of throw

Multiple Select

Question: How does the design of paper change how far a paper airplane flies?

What are the controlled variables?

• airplane design

• distance the airplane flies

• type of paper

• type of throw

• Independent variable - paper weight

• Dependent variable - distance the airplane flies

• controlled variables - airplane design, type of throw, where thrown, wind...

Multiple Choice

What step does every scientific experiment begin with?

• hypothesis
• question/problem
• procedures
• conclusion

Multiple Choice

The name of the information that you get from your experiment (you organize it into tables).

• observations

  conclusion

• data

• variables

• hypothesis

Multiple Choice

This is the group that is affected by the variable or the group that is changed.

• Control Group

• Experimental Group

• Changed Group

• Cool Group

Multiple Choice

This is the group that we will compare our experimental group to. This group stays "normal."

• Control Group
• Experimental Group
•  Normal Group
• Weird Group

Multiple Choice

This step of the scientific method is an educated guess or a prediction. 

• Hypothesis
• Research
• Observation
• Conclusion

Multiple Choice

During this step of the scientific method, a scientist would gather background information.

• Hypothesis

• Collect Information

• Observation

• Experiment

Multiple Choice

Will a construction paper air plane fly faster than an airplane made from notebook paper? Choose the best hypothesis.

• If I make a paper airplane from notebook paper, then it will fly faster than construction paper.
• Yes.
• No.
• I think the construction paper air plane will fly faster.

Multiple Choice

What is the first step in the scientific method?

• Data

• Conclusion

• No Horse Play

• Observe a problem

Multiple Choice

Testing a hypothesis often involves a(n):

• answer
• experiment
• problem
• safety check

Multiple Choice

A testable explanation to a problem that has not yet been tested. 

• data
• theory
• hypothesis
• fact

Multiple Choice

Which is NOT a step in the scientific method?

• Make observation
• Form a theory
• Collect data
• Form a hypothesis

Multiple Choice

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

• scientific method
• recipe
• data collection
• metric system
