Experiment in progress...
Currently waiting for the water to become ice cubes. All different types of surfaces are prepared.
Experiment in progress...
The ice cubes have become solid and are placed on each of the different types of surfaces. Currently, the ice cube on metal is melting quicker than the rest. The ice cube on the plastic and wax surfaces are about the same. The ice cube on paper is melting the slowest, but we cannot be sure at this stage. Waiting for the first ice cube to melt...currently, 17 minutes have past...

Safety precautions...
- Take care when pouring water into the ice-cube making tray, as to avoid spillage of water on the floor as this will result in accidents
- Do not reuse the water in any type of ways!
- Keep out of children's reach!

Aim, hypothese, material and method...
Aim: To determine on which type of surface will ice melt quicker.
Hypothese: It will melt quicker on metal as metal is supposedly be the best conductor out of the five surfaces, wood, metal, wax, paper and plastic.
Materials: Timer, different types of surfaces (metal, wood, wax, paper and plastic), ice-maker tray, fridge, tap water.
Method:
1. Pour 10ml of tap water into each of the 5 squares of the ice-maker tray.
2. Place the tray into the fridge and wait for it to become ice cubes.
3. Spread the different types of surfaces on a table in the same room.
4. Place one ice cube on each of the different types of surfaces.
5. Start the timer.
6. Wait for the ice cubes to melt.
7. Record the time shown on the timer, when the first ice cube turns into liquid.
8. Record the time shown on the timer when the 2nd, 3rd, 4th and 5th ice cubes turns into liquid.
9. Repeat steps 1-8.
10. Compare the results for both attempts of the experiment.
11. Decide whether the results are valid.
12. If yes, record and use for observations.
13. If no, then redo the experiment with slight changes.

Final, the chosen one...
The experiment that I have chosen to conduct is the experiment which aims to determine which surface will ice melt the quickest in the same environment.

Decision helping research
In order to determine which experiment I would conduct, I have done various research based on both the topics from the Internet. This will help me, as it has provided me with a load of information about each of the experiment in regards to its variables to the aim and methods.

Deciding between the last two options
First option: - To determine whether homebrand softdrnks lose their fizz faster than branded ones
Second option: - To determine on which surface will ice melt the quickest.

More ideas
Some more ideas...
- How do you bend water?
- How big can a dry ice bubble get before it bursts?
- How can you make eggs float?
- Does a balloon help amplify sound?
- In what conditions will it make possible for chocolate to melt?
- What kind of chemical reaction occurs when the iron in the steel wool starts reacting with oxygen?

Idea for SRP
Just in case my current chosen experiment doesn't work, I have come up with several other ideas. these include:
- Does consuming a certain type of energy drink improve reaction time. this can be testes by the ruler drop test.
- How do u make a paperclip float?
- Will a balloon pop if you poke a paperclip in?
- What happens to the pepper that is scattered on top of the water when you take the implanted soap away?
- What happens to the scattered pepper on top of the water if you drop a drop of detergent into the water?
- Does using a candle help reveal a message written in lemon juice?

Starting my Science Research Project...
Today, I have chosen a topic for my research project. My aim is to test whether homebrand soft drinks would lose their fizz quicker than the branded ones, such as Coke. After I have decided on my aim, I started to create a mind map on that particular topic on Bubbl.us. This then gave me further ideas of how and whether I should conduct this investigation.
