DepEd Division of Bohol Science Investigatory Project
Training and Workshop
Mock Science Congress: Comments
Presentor 1 Remarks
Title / Topic Calamansi juice and fluoride for cleaning teeth
Not using scientific terms
Motivation/Problem Effectiveness and cost
Hypothesis Calamansi effectiveness
Experimental Method Variables
No graphs; dependent, and independent , controlled variables
Results
Changes occurred...
Measurements; quantify; numbers (by how much?) with proper units
Overall Presentation Just reading the abstract; Pronunciation, gestures; Do not read. Have eye contact with the judges. PowerPoint allowed.
Presentor 2 Remarks
Title / Topic Phases of the Moon and Childbirth
Motivation/Problem Folklore – more child births during the full moon; study in France relation between full moon and accidents
Hypothesis
Experimental Method Correlational method; date and time of deliveries for a year
Results Last quarter has highest frequency; Significant degree of relationship between phases of the moon and delivery
Overall Presentation With recommendations
Open Forum
Q: Do we show calculations of mathematical results and statistical tests?
A: Yes, in the full paper. There should be a basis for your conclusions.
Honesty is very important in science.
Q: Comparative study between rural or urban setting?
A: Some data but not enough
Open Forum
CCB: Context is important; presence of confounding variables; averaging effect that negates correlation between variables
Fine-tuning: other factors – age of the women, etc.
Be your number 1 critic of your project.
Anticipate all possible questions, list and check responses. Avoid too many „For future study“ responses.
Open Forum
CCB: Stick to the scientific method. Do not love your research work too much. Otherwise, you will not be objective. If wrong, troubleshoot, and if it cannot be solved, throw it away. The judge always has the option to follow your procedure and should get your results.
Humility.
Open Forum
CCB: Data presentation: bar graphs, pie chart, aside from tables
For each slide, do not put in too much text or numbers, otherwise the reader (judge) may be irritated because he/she would have liked to read.
Literature survey
Open Forum
Q: We have no journals, are the Internet sources okay?
A: Wikipedia is good first step, leads to references in international professional journals.
Wikipedia has a self-checking mechanism, because of open-editing.
Journals published by professional societies, e.g. American Physical Society publishes the Physical Review; IEEE for engineering
Presentor 3 (CD 2) Remarks
Title / Topic Pests in rice production, kuhol
Motivation/Problem Correlation between gemelina tree and presence of kuhol; cost and preference for natural products; gemelina bark and leaves known for medicinal uses
Hypothesis Gemelina root extract, effect on kuhol
Experimental Method
Results Significant effect as natural pesticide
Overall Presentation Reading; not organized
Open Forum Q: Isn‘t gemelina poisonous? Polluting rice fields and
rivers? Kills kuhol but also kills other organisms? Is it really environmentally friendly?
CCB: That is an example of: what are the possible questions judges could ask.
Quantify results; give quantified background, e.g., normal lifetime
Scientific name of kuhol?
Impact on the environment
Q: What was read was not the abstract but the rationale? Is there a limit to the number of words?
CCB: Follow the rules: number of words, format, font
Open Forum CCB: Read sample abstract, etc., get a copy of
the most recent rules and guidelines.
(MVCB: toxicity; ethics; )
Presentor 4 Remarks
Title / Topic Biofuel from rice and corn chaff (agro-inudstrial waste)
Motivation/Problem
Hypothesis
Experimental Method Fermentation process; filtration, fractional distillation, iodoform test for alcohol purity, flame test, NPK test
Rusted equipment not allowed, no improvised (e.g. Ice cream plastic container); write chemical equation, diagram or flowchart; maintain purity of samples, reactants and products
Results Products: feeds, biofuel and fertilizer
Overall Presentation Not allowed to use clip art or animation; artwork should be original; personal photos not allowed
Open Forum Intel winner sharing:
• Importance of adult supervision
• Proper use of pathogenic organisms, hazardous substances and devices, disposal of wastes
• Acceptable norms of laboratory procedures and technical writing
• In-text citations
• Accuracy of recording of dates
Open Forum CCB: Presentation of scientific paper
published in Physics Letters A
• Sample of abstract, use of graphs, imbedded text citation
Presentor 5 Remarks
Title / Topic Used Engine Oil as Lamp Fuel
Motivation/Problem Recycling
Hypothesis
Experimental Method
Results Kerosene has bigger flame and more soot than the engine oil lamp
