Hypothesis = Prediction with a reason
If, Then – compared to, Because format

If fertilizer is applied to tulips,
Then the tulips with fertilizer will grow taller
If, Then - compared to Prediction format
compared to tulips without fertilizer

Because fertilizer has nutrients that increases tulip growth. Therefore tulips with fertilizer will grow taller.
Prediction: If fertilizer is applied to tulips,
Then the tulips with fertilizer will increase in height
compared to tulips without fertilizer….

8. Analyze the Data
• Calculate Highs, Lows, Averages • Compare Experimental data to Control data• Look for Key Differences• Identify and Interpret patterns & variations• Make inferences from the data gathered
• Identify sources of errorschmied©2013

a. State the question
b. Restate the Hypothesisc. Tell if Hypothesis is Accepted or Rejected
i. Explain why using DATA (Hi, Low, Avg etc)
9. Develop a Conclusion:
ii. Tell what you conclude from the dataiii. Make inferences from the findings
Clearly distinguish between the evidence and your explanations.
iv. Evaluate the Reliability of the datav. Tell sources of error & effect on results

Improving Validity
Let’s explore a couple ways that might improve the validity of the results from the Tulip experiment.
Assume that the original class results show the tulips with fertilizer added actually grew taller.

A. Do more trials, each with different amount of fertilizer. Goal: See if a difference in tulip height can be linked to
the amount of fertilizer given.

b. Do more trials with another plant, like daffodils. See if adding fertilizer increases daffodil height.

c. Do Tulip trials with varying concentrations of fertilizer, but add Daffodil trials too.

1. State the ProblemTake data
Make Inferencesfrom data about
a problem.
