Group Reference: A / B / C / D / E / F / G / H / J / K / L / M
A. Indicate the type of research that you are adopting:
[ ] Test a hypothesis: Hypothesis-driven research
e.g. Investigation of the anti-bacteria effect of chrysanthemum
[ ] Measure a value: Experimental research (I)
e.g. Determination of the mass of Jupiter using planetary photography
[ X ] Measure a function or relationship: Experimental research (II)
e.g. Investigation of the effect of temperature on the growth of crystals
[ ] Construct a model: Theoretical sciences and applied mathematics
e.g. Modeling of the cooling curve of naphthalene
[ ] Observational and exploratory research
e.g. Investigation of the soil quality in School of Science and Technology, Singapore
Type of research: 3 (Write down one number from 1 to 6)
Category – 10 (Write down one number from 7 to 20)
Sub-category – (g) (Write down the sub-heading alphabet)
(Refer to http://sst2016-iss.blogspot.sg/p/l2-types-of-research-categories.html)
Application of project relevant to SST Community, Society or the World:
People around the world face this problem that is fairly common thus we decided to try to find a solution to overcome it with typical things that people usually have at home and see which is the most effective.
C. Write down your research title:
Investigation of the effect of different kitchen chemicals on ink stains.
D. (a) Aim / question being addressed
We want to find out what household items can remove ink stains.
(b) Independent variable
The independent variable is the chemical used.
(c) Dependent variable
The dependent variable is the amount of ink left on the cloth.
(d) Controlled variables
(a) The amount of ink used
(b) the type of ink used
(c) the material of cloth used
(d) the size of the cloth used
(e) the amount of time the ink is soaked in the chemical
Certain household chemicals are able to effectively remove ink stains.
E. Method – Description in detail of method or procedures (The following are important and key items that should be included when formulating ANY AND ALL research plans.)
(a) Equipment list:
- Baking soda
- Lemon juice
- Nail polish remover
- Rubbing Alcohol
(c) Procedures: Detail all procedures and experimental design to be used for data collection
1. Place an equal amount of ink on several pieces of cloth of the same type and size
2. Dip a sponge into the cleaning chemical
3. Dab it onto the ink stain
4. Allow it to soak for about half an hour
5. Repeat the above steps with different cleaning chemicals
6. Place a photometer into the box
7. Take the pieces of cloth (after the experiment) and put it above a photometer
8. Place a light source above the cloth
9. Record the number on the photometer and record it on a piece of paper
10. Plot a bar graph of the amount of light that was recorded on the photometer
11. From the graph, we can find out which household item is the most effective for stain removal
(d) Risk, Assessment and Management: Identify any potential risks and safety precautions to be taken.
Inhaled fumes from rubbing alcohol can cause respiratory tract irritation.
During the use of rubbing alcohol, students have to wear masks and students cannot consume the alcohol.
Rubbing alcohol on your skin, in excessive amounts it can cause irritation and redness.
During the use of rubbing alcohol, students have to wear gloves and have to handle the bottle containing the alcohol with care.
The substances used in this experiment may cause redness and irritation in eyes if not handled properly
During the experiment, handle the substances with care and do not play around with it. If necessary, wear goggles.
(e) Data Analysis: Describe the procedures you will use to analyze the data/results that answer research questions or hypotheses
1. Record the number on the photometer and record it on a piece of paper
2. Plot a bar graph of the amount of light that was recorded on the photometer
3. From the graph, we can find out which household item is the most effective for stain removal
F. Bibliography: List at least five (5) major sources (e.g. science journal articles, books, internet sites) from your literature review. If you plan to use vertebrate animals, one of these references must be an animal care reference. Choose the APA format and use it consistently to reference the literature used in the research plan. List your entries in alphabetical order for each type of source.
