Results...

It was proven that metal is indeed the surface that melts ice the quickest. the results are:

Metal: 46 minutes
Wax: 82 minutes and 58 seconds
Wood: 109 minutes and 40 seconds
Paper: 111 minutes and 32 seconds
Plastic: 118 minutes and 16 seconds

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.
