What Will Keep Me Frozen

• Testing the effectiveness of different materials
  for insulating

3
PURPOSE

• The question Im going to ask is what insulation
  material will keep an ice cube frozen the longest?

4
HYPOTHESIS

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

5
MATERIALS

• 10 empty milk cartons
• 10 mini cups
• Water
• Freezer
• 5 different types of insulation
• Newspaper
• Cotton balls
• Tin foil
• Styrofoam
• Fiber glass insulation
• 1 pkg of cotton balls
• 1 pkg of tin foil
• Clock
• Paper

• Pencil
• Medicine syringe
• Knife
• Gloves
• Calculator

METHOD

• Wash out and dry out 5 milk cartons.
• Measure out equal amounts of water into the 5
  plastic cups using the medicine syringe.
• Put the cups in the freezer until water is froze.
• While the water is freezing cut 1 square of
  Styrofoam and place in on the bottom of a milk
  carton
• Break up some of the remaining Styrofoam into
  small pieces
• Using gloves, tear off some fiber glass
  insulation and place on the bottom of the second
  milk carton
• Put cotton balls on the bottom of the third milk
  carton
• Put crumbled up newspaper on the bottom of the
  fourth milk carton
• Finally put crumbled up tin foil on the bottom of
  the fifth milk carton

1. When the water is froze, remove the cups and
   place one cup on the bottom of each milk carton
2. In the milk carton with the Styrofoam put the
   broken pieces of Styrofoam all around the sides
   of the cup
3. In the milk carton with the fiber glass
   insulation, using gloves tear off some insulation
   and put around the sides of the cup
4. In the milk carton with the cotton balls put more
   cotton balls around the sides of the cup
5. Repeat the same for the newspaper and the tin
   foil
6. When all milk cartons are filled, close up the
   tops and record the time

7
METHOD

• A hour later, check each cup to see if any ice
  has melted
• 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.
• 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.
• Continue each hour until all ice has started to
  melt.
• Record your results in tables along with the
  average results.
• Do this experiment again repeating steps 1 20

8
VARIABLES

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

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.

13
SOURE OF ERROR

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

14
WAYS TO IMPROVE

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