Group Project Proposal (Science)
SCHOOL OF SCIENCE AND TECHNOLOGY, SINGAPORE


INVESTIGATIVE SKILLS IN SCIENCE


Names: Troy Han,Chuah Jiyou, Wong Zhuo Zheng


Group Reference: B


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



  1. Type & Category


Type of research: 1 Test a hypothesis: Hypothesis-driven research

Category  – 8 BIOCHEMISTRY (BI)


Sub-category – B General Biochemistry
`````````````


Application of project relevant to SST Community, Society or the World:
    Cleaners would know how much chlorine to pour into the swimming pool so that algae would not grow in the pool, if too much chlorine is poured in the pool, algae would grow in the pool.


C.    Write down your research title:


Investigation of the effect of chlorine and hydrogen peroxide on the growth of algae.


D.   (a) Aim / question being addressed 



(b) Independent variable
The independent variable the different types of chemical solutions.


(c) Dependent variable
The dependent variable is the mass of algae.
(d) Controlled variables
Beaker must be the same size, volume of the solutions, the starting mass of the algae, location, same type of algae


      (e) Hypotheses

Our hypothesis is that chlorine will make algae to die faster than hydrogen peroxide will.


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:
 
-5 250 ml Glass beakers
- 500ml Chlorine/bleach
- 500ml Hydrogen Peroxide
- 5 Thermometer


(b) Diagrams
DIAGRAMWAVE.jpg




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


1)Pour 200ml of Chlorine/Bleach into 2 glass beakers.
2)Pour 200ml of Hydrogen Peroxide into 2 glass beakers.
3)Pour 200ml of water into 1 glass beaker.( control set up)
4)Put 50g of algae into all 5 glass beakers.
5)Place 1 thermometer in each beaker.
6)Cover all the beakers with cling wraps
7)Measure the starting mass of each beaker
8)Observe & measure the mass of the beaker every 2day(3 weeks)






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


Risk
Assessment
Management
Breaking of glass beaker
High, as it is easy for a glass beaker to slip off our hand, especially when wearing gloves.
Be careful when handling glass beakers.
Accidental inhalation of algae spores
Low, as we are wearing mask while doing experiment.
Wear a N95 Mask and use the N95 Mask to cover up your nose.
Contact of Chemical
Low, as we are wearing gloves during the experiment
Wear gloves, be careful when pouring and handling chemicals.
Accidental ingestion of algae
Low, as we are wearing mask while doing experiment.
Wear a N95 mask.
Accidental contact of chemical in the eye
Low, as we are wearing safety glasses during the experiment
Wear safety glasses during the experiment.






Table 3: Risk Assessment and Management table


(e) Data Analysis: Describe the procedures you will use to analyze the data/results that answer research questions or hypotheses
  1. Take the initial mass of algae and the ending mass, and jot down the mass
  2. Use the mass and create a graph with the relation of mass of algae to length of experiment
  3. Notice the decline or incline of the mass of algae in relation with the length of experiment

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.
