Title: Scientific Method ReviewIn: (Top Right Side!)

Identify the Manipulated, Responding, and Controlled variables for the following scenario: Students of different ages were given the same jigsaw puzzle to put together. They were timed to see how long it took to finish the puzzle.

Notes (Right Side)• Testable Question:– A questions that has a manipulated and

responding variable and can be used to design an experiment.

– Formats for writing questions:• How does the ____ affect the _____?• What is the effect of the ____ on the _____?

– Example: How does the age of a student affect the time a student takes to complete a jigsaw puzzle?

Notes (Right Side)• Hypothesis:– A testable explanation for a specific problem or

question, based on what has already been learned. – Format for writing hypothesis:• If ____________, then ______________

because__________________________

– Example: If the age of the students increase than the time a student takes to complete a jigsaw puzzle will decrease because as student’s age they learn to identify and place object better.

Notes (Right Side)• Procedures:– Detailed directions of how to do an experiment

so that another person can repeat it exactly. 1) By making a list of all the actions required.2) By making a flow chart of all the actions required.– Procedures should include:• What and when a measurement is recorded. • An Experimental Control Group.• More than one Trial• 1 MV, 1 RV, and 3-5 CV’s• Clear Techniques for Measurement.

Notes (Right Side)• Data:– Collected information. – Qualitative:• Written Description about an object.• Example: The water is blue and tastes salty.

– Blue and Salty describe the water.

– Quantitative: • A description of an object in Numbers.• Includes a numerical value and a unit.• Example: The sample was 10 cm long.

– 10 is the numerical value– cm is the unit

Notes (Right Side)• Data:– Collected Information must be displayed in a Table– The table must include units and labelsExample:

Responding Variable(Units)

Lowest Condition

Condition 1

Condition 2

Highest Condition

Notes (Right Side)• Data Analysis:– How can the data be formatted so that the data is

more understandable. • Calculations, Graphs, and Conversions

– Where do you place the variables on a graph?

DRY— • An Acronym for:– Dependent Variable

– Responding Variable

– Y-axis (vertical/up/down)

MIX—• An Acronym for:– Manipulated Variable– Independent Variable– X-axis

(horizontal/across)

Notes (Right Side)• Data Analysis: • Create a graph based on

the data in the data table. The graph should include: – Appropriate title for the

graph.– Labeled axis with units

(DRY MIX)– Correctly numbered axis– Correctly plotted data

points.– Best Fit Line

Notes (Right Side)• Conclusion1. Decides if the hypothesis was supported, contradicted, or

inconclusive– Supported: Hypothesis and Data are the same.– Contradicted: Hypothesis and Data are opposite.– Inconclusive: I cannot draw a conclusion.

2. Uses data from the data table as evidence to support the decision in step 1.

3. Describes problems with the procedures (experimental error).

4. Describes possible laboratory improvements.5. Describes the data’s relationship to the real world and

other experiments that may stem from the data in the future

Scientific Inquiry Process

On the left side of your notebook (the activity side), please copy the following diagram.

Activity: Create a Bubble Map that Relates the different types of Variables to the

Scientific Method• Include the following words: – Responding Variable, Controlled Variable,

Manipulated Variable– Procedures, Hypothesis, Question– Data, Data Analysis, Conclusion

• On each line that connects the Bubbles, please write a word or group of words that show the relationship.
