What Will Keep Me Frozen Testing the effectiveness of different materials for insulating

PURPOSE The question I’m going to ask is what insulation material will keep an ice cube frozen the longest? The question I’m going to ask is what insulation material will keep an ice cube frozen the longest?

HYPOTHESIS I think the best insulation material that would keep a ice cube frozen the longest is the fiber glass insulation.

MATERIALS 10 empty milk cartons 10 empty milk cartons 10 mini cups 10 mini cups Water Water Freezer Freezer 5 different types of insulation 5 different types of insulation Newspaper Newspaper Cotton balls Cotton balls Tin foil Tin foil Styrofoam Styrofoam Fiber glass insulation Fiber glass insulation 1 pkg of cotton balls 1 pkg of cotton balls 1 pkg of tin foil 1 pkg of tin foil Clock Clock Paper Paper Pencil Pencil Medicine syringe Medicine syringe Knife Knife Gloves Gloves Calculator Calculator

METHOD 1. Wash out and dry out 5 milk cartons. 2. Measure out equal amounts of water into the 5 plastic cups using the medicine syringe. 3. Put the cups in the freezer until water is froze. 4. While the water is freezing cut 1 square of Styrofoam and place in on the bottom of a milk carton 5. Break up some of the remaining Styrofoam into small pieces 6. Using gloves, tear off some fiber glass insulation and place on the bottom of the second milk carton 7. Put cotton balls on the bottom of the third milk carton 8. Put crumbled up newspaper on the bottom of the fourth milk carton 9. Finally put crumbled up tin foil on the bottom of the fifth milk carton 10. When the water is froze, remove the cups and place one cup on the bottom of each milk carton 11. In the milk carton with the Styrofoam put the broken pieces of Styrofoam all around the sides of the cup 12. In the milk carton with the fiber glass insulation, using gloves tear off some insulation and put around the sides of the cup 13. In the milk carton with the cotton balls put more cotton balls around the sides of the cup 14. Repeat the same for the newspaper and the tin foil 15. When all milk cartons are filled, close up the tops and record the time

METHOD 16. A hour later, check each cup to see if any ice has melted 17. Measure the amount of water in each cup using the medicine syringe and record the amount of water in ml for each of the cups and which material it was in. 18. If all the ice has not started to melt, check again in another hour and measure and record the amount of water in the remaining cups. 19. Continue each hour until all ice has started to melt. 20. Record your results in tables along with the average results. 21. Do this experiment again repeating steps 1 – 20

VARIABLES Manipulating Variables: Manipulating Variables: The material that you use for insulation The material that you use for insulation The amount of insulation you put in each carton The amount of insulation you put in each carton Temperature of the room Temperature of the room Responding Variables: Responding Variables: The material that keeps the ice frozen the longest The material that keeps the ice frozen the longest Controlled Variables: Controlled Variables: The amount of ice in the cups The amount of ice in the cups The cups that you use The cups that you use The milk cartons that you use The milk cartons that you use

ANALYSIS

CONCLUSION In conclusion after doing this experiment, I found out that the fiber glass insulation kept the ice cube frozen the longest. My hypothesis was right because the fiber glass insulation came in first. In conclusion after doing this experiment, I found out that the fiber glass insulation kept the ice cube frozen the longest. My hypothesis was right because the fiber glass insulation came in first.

SOURE OF ERROR May not have been equal amounts of insulation in each of the milk cartons May not have been equal amounts of insulation in each of the milk cartons More water in one cup than another More water in one cup than another Some insulation went over the tops of some of the cups and not the others Some insulation went over the tops of some of the cups and not the others Crack in the cup Crack in the cup

WAYS TO IMPROVE Keep it in a controlled temperature environment Keep it in a controlled temperature environment Use a better measuring device Use a better measuring device Find a way to put insulation on top of all the cups Find a way to put insulation on top of all the cups Use cups that can not crack Use cups that can not crack Find a way to have the same amount of insulation in each of the containers Find a way to have the same amount of insulation in each of the containers
