INVESTIGATIVE SKILLS IN SCIENCE
Names:
Class: S2-0_______
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

[X ] 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

[ ] 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: Investigation on why wire tangles.

A. Question being addressed


A student wanted to find out what temperature is the best for making the biggest crystals.
The independent variable is length of the wire
The dependent variable is the number of tangles.
The constants are:
Size of the box
Type of wire.
Thickness of wire.
Time used to shake

B. Hypotheses


The hypothesis is the longer the wire,the more tangles.


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:
-Box
-Wire


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

1st experiment:We are testing for the length of the wire and how it will affect the amount of tangles
1.Place shorter wire into box
2.Shake for one minute
3.Count the number of tangles
4.Repeat with longer wire
2nd experiment:We are testing for the thickness of the wire and how it will affect the amount of tangles
1.Place thicker wire into box
2.Shake for one minute
3.Count the number of tangles
4.Repeat with thinner wire
3rd experiment:We are testing for the weights at the end of a wire and how it would be affecting the amount of tangles
1.Put wire with weights into box
2.Shake for one minute
3.Count the number of tangles

4.Repeat with wire without weights

Method

Our method:Every time a wire goes under and over the other wire,it is counted as one knot.Only by going under and over another wire,it creates a knot,thus we used this method to count number of knots/tangles in the wire.From the above example,we tried to understand the diagram,we started off by counting by each time it goes under and over one wire and that is the only idea we had from the diagram.So we decided to use that as our method for counting the amount of knots.
• Risk and Safety: Identify any potential risks and safety precautions to be taken.
-No risks are involved in this experiment

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


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.
