PURPOSE

To observe which is the best insulating

material.

To understand which material would

keep warm.

HYPOTHESIS

I think that the woolen sock is the best

insulating material.

I think that the newspaper is the worst

insulating material.

MATERIALS REQUIRED

Thermometer

4 Plastic Bottles(didn’t have glass bottles)

Hot Water

Newspapers

1 Woolen Sock

1 Plastic Bag

Aluminum Foil

PROCEDURE1. Gather all the materials together.

Gather everything on my ‘Materials Required’

list.

2. Wrap the insulating materials around the

bottles.

Paste the insulating materials(the

newspaper, plastic bag, woolen sock and

aluminum foil) over the bottles.

3. Pour the hot water inside the bottles.

All the hot water was approximately 42

(C), which is perfect for the experiment.

PROCEDURE(cont.)4. Take the temperature of the water before

anything happens.

The temperature all should’ve been above 104 F, but

my bottles are still above 104 F.

5. Record the temperature for 5 minutes.

6. Take the temperature again for 10 minutes.

7. Record the temperature again for 20 minutes.

CONCLUSION(cont.)1. The temperature of the aluminum foil bottle

dropped down slower than the others.

2. The temperature of the plastic bag bottle dropped

down faster than the others.

The temperature of the aluminum foil dropped down

the least(only 2.2 C)

This means the aluminum foil is a good

material, though it is not very thick.

This also means that I wrapped 10 layers of

newspapers which equaled to the same insulation

of the woolen sock.

THE BIG IDEA

Different materials has different abilities to contain

heat.

We must use the right material for the right job, or

else you wouldn’t get the result you want.

Materials that are thicker can hold more heat, but

if we want to release heat quicker, then we can

use thinner materials(not aluminum foil).
