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.
