C. Write down your research title:
Development of a SMART and GREEN energy system for households
D. (a) Problem being addressed
Non-renewable energy is creating more problems for mankind rather than solving it. For example, Nuclear energy and Fossil energy can produce potentially harmful consequences if they are not managed properly. One is a nuclear pollution, and the other is the green house effect that leads to global warming.
(b) Goals
A student wanted to cut down on electricity bills using SMART and GREEN technology that is available in the market today.(c) Specify Requirements
In particular, he wanted to
(a) Control the lights to the house using Light sensor system
(b) Control the opening of doors using the rainwater sensor system
(c) Control the air con / fan using the temperature sensor system
(d) Collect energy by using solar energy and storing the energy in a rechargeable battery

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:
- clean beaker (250 ml) x 10
- copper sulphate in powder form
- stirrer
- Bunsen burner
- Lighter
- Weighing machine
- Magnifying glass
- Silica gel
- refrigerator (-10 degree celcius to room temperature)
- incubator oven ( room temperature to 50 degree celcius)
- chopsticks x 100
(b) Diagrams
Figure 1: Diagram of prototype
(c) Procedures for building: Detail all procedures for construction of prototype
1. Set up the experiment as shown in the diagram above.
2. Pour 50 grams of copper sulphate crystals into a beaker of 200 ml of distilled water and dissolve it using a stirrer.
3. To ensure that the concentration of copper sulphate is saturated, heat the beaker using a Bunsen flame so that we can dissolve the maximum amount of copper sulphate.
4. When we observe that the crystals cannot be dissolve any further due to heating and stirring, stop the heating process.
5. Pour equal amounts of the copper sulphate solution into 6 different beakers of different amounts. (e.g. 25 ml each)
6. Make sure that the seeding crystals used to make the big crystals are of the same shape by using a magnifying glass to inspect.
7. Make sure that the seeding crystals used to make the big crystals are of the same mass by using a weighing machine.
8. Place the seeding crystals into the 6 different beakers.
9. Place the 6 different beakers into refrigerator and the incubator ovens set according to the temperatures specified.
10. To ensure that the humidity of the space above the beakers remains the same, place a packet of moisture absorber (silica gel) in each of the refrigerator and the oven so as to make sure that the humidity is low. This is to make sure that there is no condensation of water vapour in the refrigerator and oven into the beaker of copper sulphate.
11. Wait patiently for a period of 5 days without disturbing the 6 beakers of copper suphate solution.
12. After 5 days, remove the beakers from the refrigerators or ovens and remove the seeded crystal using a pair of chopsticks carefully.
13. Measure the final mass of the grown crystal using a weighing machine.
14. Repeat the experiment again using a similar setup and measure the average mass of the grown crystal again.
(d) Procedures for testing: Detail all procedures for testing of prototype
<describe in detail, how the prototype will be tested>
(e) Risk, Assessment and Management: Identify any potential risks and safety precautions to be taken.
Table 4: Risk Assessment and Management table
Risk
|
Assessment
|
Management
|
The chemicals used are poisonous. If accidentally consumed, will
cause the student to faint or have stomach flu.
|
High
|
Students must wear gloves when carrying out the experiment.
Students must not eat or drink during the experiment. Students must wash
their hands before and after experimentation.
|
As the experiments involve heating, there is a risk of fire if
the flame accidentally touches any flammable material.
|
Medium
|
Make sure that there are no flammable materials near the heating
apparatus.
|
As the experiments involve heating, there is a risk of scalding
the hand accidently.
|
Low
|
Use mittens or thongs when carrying out the experiment
|
As the experiment involves glassware, there is a risk of breakage
and cutting of the hands.
|
High
|
Wear gloves when carrying out the experiment. In case of
breakage, the cut to the hands will be minimized.
|
Legend
|
Low
|
Unlikely and no severe harm
|
Medium
|
Likely but not severe OR Unlikely but severe
|
|
High
|
Likely and Severe harm

(f) Data Analysis: Describe the procedures you will use to analyze the data/results that answer engineering goals
1. Tabulate the data and calculate the average mass of the grown crystal.
2. Plot a graph of the average mass of the crystal against the temperature in which it is grown.
3. From the graph, we can find out what temperature is the best for making the biggest crystals. (The aim)
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.
