Names:
Class: S2-01_______
Group Reference: A / B / C / D / E / F / G / H   

1.    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

  ] 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 

x ] Observational and exploratory research
e.g. Investigation of the soil quality in School of Science and Technology, Singapore  

[    ] Improve a product or process: Industrial and applied research
e.g. Development of a SMART and GREEN energy system for households  


2.    Write a research proposal of your interested topic in the following format:

Title: An investigation on the water quality at the re-directional canal in Bukit Timah.

A.    Question being addressed


We want to find out about whether the re-directional canal’s water quality would be any different from the water quality of water from the Sungei Ulu Pandan reservoir.
The independent variable is the location
The dependent variable is the amount of pollutants in the water.
The constants are:
(a)  The weather
(b)  The collection points of the water
(c)  The time of day we collect the water
(d)  The amount of water we test in each sitting
(e)   The factors we test for in the water in each sitting

B.    Hypothesis


The hypothesis is that the water at Sungei Ulu Pandan reservoir is cleaner than the water at the re-directional canal.




C.    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.)

Equipment list: 
-       Clean beaker (250 ml) x 8
-       Turbidity sensors
-       De-ionised water
-       Thermometer (To be connected to data logger)
-       Data logger
-       Dissolved oxygen sensor
-       Buckets (small) with lid x 8
-       Nylon rope
-       Calcium sensor
-       Ammonia sensor
-       pH sensor
-    Microscope
-    Sedimentation sensor
-    Toxicity sensor
-    Chlorophyll sensor
-    Dissolved carbon dioxide sensor

• Procedures: Detail all procedures and experimental design to be used for data collection

1.    Bring the 8 buckets, data logger, thermometer, Dissolved oxygen sensor, Dissolve carbon dioxide sensor, De-ionised water, Nylon rope to re-directional canal.
2.    Each collection point that we chose Is marked on the map, and at each collection point, use the bucket and rope to collect some water from the canal.
3.    Test for the Dissolved oxygen, Temperature and dissolved carbon dioxide on-site, at each collection point.
4.    Bring back samples of water collected from the collection points to school so that we can test for Toxicity, Turbidity, Calcium, Ammonia, Bacteria, pH level, Sedimentation and chlorophyll.
5.    Take down all the results for each test.
6.     Bring the 8 buckets, data logger, thermometer, Dissolved oxygen sensor, Dissolve carbon dioxide sensor, De-ionised water, Nylon rope to Sungei Ulu Pandan reservoir
7.    Go to the allocated collection points and collect water samples. Test for Dissolved oxygen, Temperature and dissolved carbon dioxide on-site, at each collection point.
8.    Bring back samples of water collected from the collection points to school so that we can test for Toxicity, Turbidity, Calcium, Ammonia, Bacteria, pH level, Sedimentation and chlorophyll.
9.    Take down results for each test.



• Risk and Safety: Identify any potential risks and safety precautions to be taken.

1.    As this experiment requires us to trek into the forest where there might be dangerous animals or insects, as well as branches that we might trip on.
2.    As the experiment requires us to obtain water from canals we have to make sure we do not fall inside.
3.   As the experiment requires us to handle untreated water, we have to ensure that any of the potentially harmful substances from the water do not entre our bodies.

• Data Analysis: Describe the procedures you will use to analyze the data/results that answer research questions or hypotheses

1.    Tabulate the data and compare the results of water samples of Sungei Ulu Pandan reservoir and Re-directional canal
2.    Come to a conclusion and check if our hypothesis was correct.

D. Bibliography: List at least five (5) major references (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.
