  • Ask students what format of results they have seen before.Textual formats (descriptive paragraphs, tables)PPictorial formats (pie charts, bar graphs, line graphs, photographs, electron micrographs, etc)
  • Ask students what experiments may require textual presentation of the outcomes.
  • Ask students what experiments may require textual presentation of the outcomes.
  • Ask students what experiments may require graphic representation of the outcomes.
  • Ask students what experiments may require graphic representation of the outcomes.
  • Ask students what experiments may require combinatorial representation of the outcomes.
  • Appendix A: Class list with randomly filled up heights of the students.
  • Scientific report writing 3 results and discussion

    1. 1. Presenting Results; 3Explaining and Discussing the Results
    2. 2. • Introduction Writing •Based on 5Ws and 1H •Giving an overview to a topic or project• Methods Writing •Converting an experimental protocol to a method by explaining the different actions
    3. 3. • Results Presentation• Discussion Writing
    4. 4. • Textual formats• Pictorial formats• Combination formats
    5. 5. • Textual formatsAfter 8 days, Dendrobium placed in organic vermicompost tea has asmaller percentage of flowers and buds left as concentration decreases.Organic 1:30 prolonged shelf life of Dendrobium but insignificantly, with aT-test, p-value > 0.05. Shelf lives of Dendrobium placed in papervermicompost tea were all prolonged by paper vermicomposts teas andthey were prolonged more with decreasing concentration. After 15 days,organic vermicompost teas produce an indistinct trend for the differentconcentrations with only organic 1:30 tea prolonging shelf life whencompared to the control. Similarly, the paper vermicompost teas have nogeneral trend. Paper 1:90 and 1:120 teas prolonged shelf life comparedto control. In conclusion, Dendrobium cut orchids grown in vermicompostteas in the home environment showed no significant prolong in shelf-lifewhen compared to the control.
    6. 6. • Textual formats
    7. 7. • Pictorial formats
    8. 8. • Pictorial formats
    9. 9. • Combination: Textual & Pictorial
    10. 10. • A teacher wanted to find out the average height of all the boys and all the girls in a class.• Raw results are given in Appendix A.
    11. 11. • Task (30 min) •In groups of 4s, discuss and decide which is the best way to present the results. •Present your results to the class and explain why you think this format is the best way to present the results. •Your presentation should be on powerpoint if possible.
    12. 12. PRESENTATION OF RESULTS
    13. 13. • In any Scientific experiment, it is essential for scientists to explain the results.• This explanation of results is called the “discussion”.
    14. 14. • Some elements that can be included in the “discussion” segment are: • Explanation of the results • Did the results support the hypothesis? Why or why not? • Why did they choose this method of experimentation? • Were there any “unexpected” results? Can these “unexpected” phenomenon be explained? • Are these results comparable to previous similar studies conducted by other scientists?
    15. 15. • Task (15 min) •Based on the same scenario given in Activity ONE, discuss and come up with a well-elaborated and convincing explanation for the difference in the average heights of boys and girls in the class. •Present your discussion to the class on the same powerpoint.
    16. 16. PRESENTATIONOF DISCUSSION
    17. 17. • Save your group’s powerpoint.• File name should be in the following format: Class-GrpLeader’sName- ResultsDiscussion2012 eg. 1E1-Huifang-ResultsDiscussion2012• Upload your group’s powerpoint onto the Applied Science Wiki page.
    18. 18. • Introduction Writing• Methods Writing• Results Presentation• Discussion of Results
