Methods : In two paragraphs , describe how the phototropism experiment was conducted . Include the following points :
Experimental design : Describe treatments for the test seedling , and positive and negative controls . Why does the experiment include all three treatments ? What does each treatment allow you to understand ?
Data collection : How did you collect data ? Over what time period was it collected ?
Results : In no less than two paragraphs , describe the results . Include the following points :
Begin with a one- or two-sentence summary of your findings .
Include the graph generated from your spreadsheet . Your graphs must be labeled . Summarize results discovered in each graph and compare results .
Discussion : In no less than four paragraphs , describe your findings and consider their importance to plant science . Include the following points :
Summarize findings . State whether or not your hypothesis was supported .
Explain how phototropism occurs . Include at least one explanation from the textbook . Do your results allow you to support the explanation with 100 % certainty ? Why or why not ?
Conclusion . Offer a summary of your findings . Indicate how this experiment will help scientists understand phototropism . Offer at least one example of what still must be learned about phototropism .
