Group Project Proposal (Science)
SCHOOL OF SCIENCE AND TECHNOLOGY, SINGAPORE
INVESTIGATIVE SKILLS IN SCIENCE
Names: Pey Ruo-Yang, Matthew Chew, Jonas Tua, Toh Yong Jiang
Class: S2-08

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

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  

[    ] 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:
Effect of impurities in water for melting and boiling point.


A.    Question being addressed
A student wanted to find out if the amount of impurities added into water will affect it’s melting and boiling point.
The independent variable is amount of salt used.
The dependent variable is the amount of impurities added into the water
The constants are:
(a)  Amount of water used

B.    Hypotheses

The hypothesis is
the more the impurities added, the slower it will take for the water/ice to melt/boil.




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: 
-       Measuring Cup
-       Salt
-       Spatular
-       Weighing machine
-       Pot
-       Ice tray
-       refrigerator (-10 degree Celsius to room temperature)
-       Stove (to heat the water)
-       Timer
-     Datalogger and Temperature sensor 











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

1.    Prepare 250ml of distilled water and 5 grams of salt and place in a beaker
2.    Put in over  hot plate and the temp. seƱor connected to a cataloguer
3.   Stand the heater until the water boils off
4.    Record the temperature with time and wire data logger and temperature sensor
5.  Repeat 2 more times and record the average
6.   Repeat the expire. with 10g, 15g, 20g,25g,30,g of salt from 1 to 5
• Risk and Safety: Identify any potential risks and safety precautions to be taken.

1.    As this experiment involves heating, use mittens or thongs when carrying hot liquids.

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

1.    Tabulate the data and calculate the average mass of the time taken
2.    Plot a graph of the average time taken by the impurities
3.    From the graph, we can find out which impurities best affect the boiling/melting point of pure water(The aim)

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.
