Section 1 Review

Scientific Method- an organized set of investigation procedures

• State the Problem

• Gather Information

• Form a hypothesis- a possible explanation for a problem using what you know and what you observe

• Test the hypothesis- experiment

• Analyze data

• Draw Conclusion

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

Multiple Choice

What step does every scientific experiment begin with?

• hypothesis

• question/problem

• procedures

• conclusion

Multiple Choice

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

• data

• theory

• hypothesis

• fact

Qualitative Observations

descriptive observations made with our senses of sight, taste, hearing, smell, and touch

Quantative Observations

• objective method of data analysis that measures research variables using numerical and statistical parameters.

Inference

a conclusion reached on the basis of evidence and reasoning.

Prediction

a guess about what will happen

Multiple Choice

A prediction is most like a(n)

• math problem.

• educated guess.

• memory of a past event.

• observation about the text.

Multiple Choice

• qualitative

• quantitative

Multiple Choice

Your teacher has asked you to explain the difference between quantitative and qualitative observations. Which statement is correct?

• Quantitative observations use numbers, qualitative uses the senses.

• Quantitative observations use the senses, qualitative uses numbers.

• Quantitative observations use measurement, qualitative uses numbers.

• Quantitative observations use colors, qualitative uses the senses.

Multiple Choice

Read each statement. Then choose whether the statement is an observation, inference, or prediction.

• The type of plant

• Height of the plant

• Color of the light the plant is in

Multiple Choice

An experiment is performed on plants to see how different liquids affect plant growth. Each plant in the experiment is given a different liquid; water, apple juice, or milk. Each plant has the same amount of soil, sunlight, and listens to the same music. In this investigation, the independent variable is ...

• The type of plant

• The amount of sunlight

• The type of music

• The type of liquid

Multiple Choice

What's the dependent variable?

• increase the amount of iron in your blood

• spinach you eat

Multiple Choice

Dependent variable means

• the scientist controls what to test

• educated guess

• ask a question

• what is being measured

Multiple Choice

What is a factor that the experimenter has full control over and changes to see what happens?

• Dependent Variable

• Independent Variable

• Control group 

• Hypothesis

Multiple Choice

What is a factor that changes because of what the experimenter does?

• Dependent Variable

• Independent Variable

• Control Group

• Hypothesis

Multiple Choice

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

• dependent variable

• independent variable

• data

• control group

Multiple Choice

These are variables that are kept the same throughout all experimental groups to prevent error in the experiment.

• Independent Variable

• Dependent Variable

• Controlled Variable

• Varying Variable

Multiple Choice

• Which song does the audience prefer?

• Which instrument does the audience like best?

• Which reed length creates the best sound?

• How do applause affect performance?
