The Materials Used

• First, one glass cup, one foam cup, and one plastic cup are all filled with water at 75 degrees Fahrenheit. They are then placed in a pan filled with water at 150 degrees Fahrenheit.

• After waiting exactly five minutes, the temperature of each cup is taken with a thermometer.

• The process is performed three times.• Finally, the insulator with the lowest temperature is

determined.

The Procedure In Order

The purpose of this experiment is to find out which type of insulator absorbs heat the most. Cups of the same size but different types are filled with water of 70 degrees Fahrenheit. The cups are then placed in a pan containing water with a temperature of 150 degrees Fahrenheit. They are left in the pan for five minutes. After this time is over, the temperature from all of the cups are taken. This same process is repeated three times until the insulator with the coolest average is determined. At the end of the experiment, it was found that the type of insulator does affect the amount of heat transferred. The glass insulator was the best insulator, having transferred the least amount of heat. It had an average of 82.3 degrees Fahrenheit.

• After I conducted this experiment, I found out that the type of insulator does affect the amount of heat transferred.

• In conclusion, glass is the best type of insulator because it transferred the least amount of thermal energy to the water in the cup. It had an average temperature of 82.3 degrees Fahrenheit.

• The next best insulator was foam with and average of 87.67 degrees Fahrenheit.

• Finally, the worst insulator was plastic. It had the highest average temperature of 94.67 degrees Fahrenheit.

Which of the following substances will have the lowest temperature, there fore , best insulation? a) Water b) Coke c) Milk

Different Substances

• If the substance inside the insulator is coke, then the insulation will be better.

• Null Hypothesis: The type of substance will have no affect on the insulation.

• Independent: The independent variable in this experiment is the type of substance inside the insulator

• Dependent: The dependent variable in this experiment is the temperature inside the insulator.

Device

• First, three plastic cups are each filled with coke, water, or milk.

• Next, the plastic cups are placed in a pan with water at 140 degrees Fahrenheit.

• The cups are there for 5 minutes.• After the five minutes past, the temperature of

each substance is taken.• Finally, the substance with the lowest

The purpose of this experiment is to determine which substance has the best insulation. First three plastic cups are filled with coke, water, or milk. The cups are then placed in a pan with water at 140 degrees Fahrenheit. Next, the cups are left there for five minutes. Finally, the temperature of each substance is taken and the lowest temperature is determined. At the end of the experiment, it was discovered that the type of substance has no affect on the insulation. Each substance had the same temperature of 110 degrees Fahrenheit. So, my null hypothesis was correct.

Which of the following insulators have the best insulation?a)Thinnest insulatorb)Medium thick insulatorc)Thickest insulator

Different Thickness Insulators

• If the insulator is thicker, then the insulation will be better.

• Null hypothesis: The thickness of the insulator has no affect on the insulation.

• Independent: The independent variable in this experiment is the thickness of the insulator

• Dependent: The dependent variable in this experiment is the temperature of the substance.

• First, the thickness of two plastic cups is increased by placing two other plastic cups inside on plastic cups and one plastic cup inside another. One plastic cup is left alone.

• Next the three cups are placed in a pan with water at 150 degrees Fahrenheit.

• The timer is set to 5 minutes.• Finally, the temperature of the water inside each

insulator is taken and the insulator with the lowest temperature is determined.

The purpose of this experiment was to find out if the thickness of the insulator affects the insulation

First, the thickness of each insulator was increased by adding several cups. Next, each insulator was placed in a pan with water at 150 degrees . The timer was then set to 5 minutes. After five minutes, the temperature of each insulator was taken. Finally, the insulator with the lowest temperature is determined. At the end of this experiment, I found out that the thickness does affect the insulation. I found the thickest cup had the

lowest temperature.
