Writing a conclusionStart by making sense of the data table.

Your conclusion has five sentences:– The hypothesis was [correct/incorrect]– The high average data point & m/v…– The low average data point & m/v…– The difference between…– Conclusion statement with science

Start by finding the HIGH average data pointThen circle it.

Also circle the manipulated variable for the high average data point

Do the same for the LOW average data pointThen circle it.

Again, circle the manipulated variable for the LOW average data point

Writing a conclusion

“The hypothesis was _________.”

Fill in the blank with

Period.

correct OR incorrect

Writing a conclusion

“The hypothesis was correct.”

OR

“The hypothesis was incorrect.”

That’s it.

Writing a conclusionHypothesis Pitfalls

• Using pronouns & names (I, me, my, her, she, him, they, he…)

• Using any these words: “right, wrong, invalid, not correct/not incorrect, true, false, conclusion”.

• Writing your conclusion statement as part of your hypothesis.

Writing a conclusionIdentify each as right or wrong:

1. “My hypothesis was correct.”2. “The hypothesis was wrong.”3. “The hypothesis was correct.”4. “Daniel’s hypothesis was

incorrect.”5. “Godzilla’s conclusion was

correct because gigantic reptiles are always right.”

Writing a conclusion

“The high average data point was ______ for ________.”

Fill in the blank with the number and the unit

The manipulated variable

The high average data point is 66The unit is secondsThe manipulated variable is Ralph

Writing a conclusion

“The high average data point was

66 seconds for Ralph.”

Writing a conclusionHigh Av. Data Point Pitfalls

• NOT INCLUDING THE MANIPULATED VARIABLE!

• Forgetting your unit.

• Selecting the wrong data point (rarely happens with you guys).

Writing a conclusion

“The low average data point was ______ for ________.”

Fill in the blank with the number and the unit

The manipulated variable

The low average data point is 48The unit is secondsThe manipulated variable is Daniel

Writing a conclusion

“The low average data point was

48 seconds for Daniel.”

Writing a conclusionLow Av. Data Point Pitfalls

• NOT INCLUDING THE MANIPULATED VARIABLE!

• Forgetting your unit.

• Selecting the wrong data point (rarely happens with you guys).

Writing a conclusion

“The difference between the high average data point and low average data point

was ______.”

Subtract the high average data point from the low average data point and tack on the unit

The high average data point is 66

The unit is seconds

The low average data point is 4866 – 48 = 18

Writing a conclusion

“The difference between the high average data point and the low average data

point was 18 seconds.”

Writing a conclusionDifference between… Pitfalls

• Forgetting to do this step.

• Forgetting your unit.

• Incorrect subtraction (rarely happens).

Writing a conclusionConclusion statement with science!

• Give any scientifically based explanation that would support the hypothesis as correct or incorrect.

• You can often find this information in the description or you can use what you know from class!

Writing a conclusion

“This is because Daniel’s long legs helped him run faster than everyone else.”

Writing a conclusionConclusion statement without science!

• Makes me sad.

• Example:– “This is because Daniel is The Flash.”

Writing a conclusionConclusion statement… Pitfalls

• Writing your conclusion in your hypothesis.

• Forgetting to include your conclusion.

• Not giving a scientific reason

• Saying “I don’t know”.

Writing a conclusionThis is really just a fill in the blank game

• Read the introduction & hypothesis.• Circle the high average data point, its unit, and its

m/v.• Circle the low average data point, its unit, and its

m/v.• Subtract the high and the low average data points• Decide if the data supports the hypothesis (is

correct) or does not support the hypothesis (is incorrect).

• Come to a conclusion statement with science

Writing a conclusion

The hypothesis was (correct/incorrect). The high average data point was (high Av. Data point w/ unit) for (manipulated variable). The low average data point was (low av. Data point w/ unit) for (manipulated variable). The difference between the high average data point and low average data point was (high minus low w/ units). This is because (scientific explanation).

Writing a conclusionCommon Pitfalls

• Not including the manipulated variable.

• Forgetting any of the five sentences.

• Forgetting your units

• Not saying things word for word as Mr. Beckstead wants it.

Let’s Practice!

Ms. Jarnagan wonders if what she drinks while playing Super Meat Boy changes how quickly she can complete a level. She decides to test this by playing the same level over and over again while

drinking water or tea or coffee or Power Thrist. (note, Ms. J has played this level

enough to not be a factor in her time

Let’s Practice!

Hypothesis: Drinking Power Thirst will result in the fastest time to beat a level.
