Scientific Method Review PLM 092914 Review Worksheets Cornell Notes

Title: Scientific Method Review In: (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 labels Example: Manipulated Variable (Units) Responding Variable Trial 1 Trial 2 Trial 3 Trial 4 Average Lowest Condition Condition 1 Condition 2 Highest Condition

MIX— DRY— Notes (Right Side) Data Analysis: An Acronym for: 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? MIX— An Acronym for: Manipulated Variable Independent Variable X-axis (horizontal/across) DRY— An Acronym for: Dependent Variable Responding Variable Y-axis (vertical/up/down)

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 Caption: This graph shows a positive correlation between increasing temperature and increasing breathing rate of goldfish

Notes (Right Side) Conclusion 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. Uses data from the data table as evidence to support the decision in step 1. Describes problems with the procedures (experimental error). Describes possible laboratory improvements. 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.
