Procedure
1. Turn on the hot plate.
2. Place the beaker on the top of the hot plate with 1,000 ml of water.
3. Wait until the water boils at 100 degrees celsius (put a thermometer inside to check the temperature.)
4. In the meantime cut the aluminum foil (A, B and C) 30 cm by 30 cm each one.
5. Put the 3 cut out aluminum foils (A, B and C) on the table.
6. The put one beaker (200ml) on top of each type of aluminum foil.
7. You should have 3 foils and 3 beakers (200 ml each) set on the table ready.
8. Then you put a thermometer inside of each beaker.
9. Make sure you have them all at the same temperature.
10. Make sure you label which aluminum foil is which so that you have the correct data recorded.
11. Now, the water will be boiling or close to boiling, slowly and with help if needed grave the pliers and grave the beaker and fill each beaker with the same amount of water (around 1/3 of the boiling water per beaker.)
12. Wrap all the way up the aluminum foil on the beaker (shown on the pictures below) and make sure that they are well covered (and record the temperature that you start with at 0 minutes.)
13. Turn off the hot plate, and leave the 1,000 ml beaker in a surface were it can cool off (throw the water out first.)
14. Start the timer, to 10 minutes, you have to record how much has the temperature decreased each 2 minutes (do this for all 3 aluminums.)
15. Repeat step 13 for another 8 minutes and record data 4 more times.
16. Now that you are done carefully open the foils so that the water can cool off.
17. Take the thermometers out of the beakers, dry them and place them on the table.
18. Slowly with the pliers grave one 200 ml beaker and throw the water in the sink and put it back on the table.
19. Do step 18 for the other 2 beakers.
20. Now throw away the foils, so that your area is now clean.
21. Now take time and look at your data table, and look at which aluminum preserves the most heat, and which one get ride of it much faster than others.
22. Do all of this steps 2 more times so that you can have 3 trials recorded in your data table.
