INVESTIGATIVE SKILLS IN SCIENCE

Names:  Caleb Ng (14), Kenneth Phoe (23), Justin Tang (25)



Class: S2-08

Group Reference:  B
A.    Indicate the type of research that you are adopting:

[  x ] 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 

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


  1. Type & Category 

Type of research:    1     

Category  –             16   

Sub-category –        C     























Application of project relevant to SST Community, Society or the World:

The project test for the amount of salt that the water hyacinth can take in. Salt is classified as a type of pollutant. Meaning the experiment can see if the amount of pollutants that the plant can take in to see if it is a suitable cleaning agent to remove pollutants that can harm other living organisms. 














C.    Write down your research title:

Investigation of effect of  water hyacinth in different amount of salt




















D.   (a) Aim / question being addressed

A student wanted to find out the effect of different amount of salt on the water hyacinth

(b) Independent variable

The independent variable is the type of plants used.

(c) Dependent variable 

The dependent variable is the amount of salt.

d) Controlled variables

(a)  The same type & volume of water used
(b) The location the plants are kept
(c)  The type of water
     (d)  Same type of salt
       (e) Hypothesis

Based on my research, we suspect that water hyacinth is good at removing salt from the water




 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:

 -       clean beaker (250 ml) x 12





















water hyacinth x 12























-salanity sensor

















salt 50g







(b) Diagrams


















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




 1)Get sodium chloride around 50 g
2)Start growing of the 6 water hyacinth and in 6 different salt concentration, check back on plant every 24 hour and record observations of plants and record it down
3) After waiting for 1 day, measure salanity and Observe for another 6 days and measure salt again




(d) Risk, Assessment and Management: Identify any potential risks and safety precautions to be taken.










































(e) Data Analysis: Describe the procedures you will use to analyze the data/results that answer research questions or hypotheses
Plot a  histogram

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.
