V.  Drawing Conclusions

This is the point of your experiment when you determine if your hypothesis is correct or incorrect.  It is also when you discuss any errors that may have happened during your experiment and why your experiment turned out the way it did.  Most importantly it is when you answer your question.

 

Below is a 2 paragraph format for how to write a conclusion.  Paragraph 1 is a recap of what you did, Paragraph 2 is where you answer your question and make inferences about what affected the outcome of your experiment.

 

 

 

2 Paragraph Conclusion Format:

 
Paragraph 1: Your hypothesis

·       State your question.

·       State your hypothesis.

·       Was your hypothesis correct or incorrect?

·       Give some evidence, from you data, to support this.

Paragraph 2: Making Inferences

·       What is the answer to your question?

·       Why DO YOU THINK your experiment turned out the way it did? (make inferences)

·       Any problems?  Explain them and the impact they had on the results.

·       What further studies can you do that are related to this topic?

 

 


Example:

For this project we tried to see what would happen to the amount of beach erosion if we change the size of the particles.  In our hypothesis we thought that if we change the size of the particles, then the larger particles would erode the least because it takes more energy to move the larger particles. According to the data, this hypothesis turned out to be correct. I say this because the beach made of rocks (the largest particle) eroded the least with an average difference of .3 cm. Also because the beach made of powder (the smallest particle) eroded the most with a difference of 4.8cm.

 

        From this experiment we learned that sediment size does have an effect on erosion. I think this happened because the waves we made did not have enough energy to move the larger particles.  The powder on the other hand was so small that the waves picked the powder particles, moving them into the water, making the pile smaller.  One thing that may have affected the results is the fact that the powder was eroding even before the waves were made.  This could result in the powder eroding less overall.   The next time I do this experiment I would use sand (because that is what most beaches are made of) and see how the sand is affected by waves over different periods of time to see how time affects wave erosion.

 

 

 

NOTE:  The underlined parts are universal and can be applied to just about any conclusion!!!!
