Significance Of The

Study

Page 3: Mathew Ang Sean Braganza Lenard Cheng Lawrence Chu Ethan Cu Brian De Guzman Paul Gue Dwight Ong Marc Ong Ryan Tan Mathew Yap TOPIC DEFENCE: WHAT MATERIAL

- guides us on how we can prevent

heat loss efficiently

- to know which type of clothing we

should use in times of cold and hot

seasons.

- to discover if the prices of these

types of cloth are worth the price in

terms of insulation strength

Why Cloths?

Page 5: Mathew Ang Sean Braganza Lenard Cheng Lawrence Chu Ethan Cu Brian De Guzman Paul Gue Dwight Ong Marc Ong Ryan Tan Mathew Yap TOPIC DEFENCE: WHAT MATERIAL

Cloths are environmental friendly compared to

other insulative goods like leather and animal skin.

They are environmental friendly because compared

to using metals, cloths decompose faster. Things

that decompose in a long period of time stays here,

on Earth, and takes up the space for how many

years. It contributes to the destruction of our

environment. Compared to using a metal

canister/thermos, this is a lot easier to construct.

Why Choose These Types Of Cloths?

Page 7: Mathew Ang Sean Braganza Lenard Cheng Lawrence Chu Ethan Cu Brian De Guzman Paul Gue Dwight Ong Marc Ong Ryan Tan Mathew Yap TOPIC DEFENCE: WHAT MATERIAL

We chose the three types of cloth; silk, cotton and polyester. But

before choosing them, we thought of the types of cloth that have an impact in our society. First, silk

and cotton, as we all know, are very common to all of us. Silk is worn

often as gowns, while the high and the low class all wear cotton.

Therefore, by experimenting using them, a lot of people will benefit

from it. But why polyester? Polyester is worn, but not as often

as the others. We chose this because the polyester's properties

are different compared to the others.

Things That You Should Know.

Page 9: Mathew Ang Sean Braganza Lenard Cheng Lawrence Chu Ethan Cu Brian De Guzman Paul Gue Dwight Ong Marc Ong Ryan Tan Mathew Yap TOPIC DEFENCE: WHAT MATERIAL

What Is Heat

Energy?

Page 10: Mathew Ang Sean Braganza Lenard Cheng Lawrence Chu Ethan Cu Brian De Guzman Paul Gue Dwight Ong Marc Ong Ryan Tan Mathew Yap TOPIC DEFENCE: WHAT MATERIAL

Heat energy is contained in molecules as

vibrations . If there is more vibration, more heat

is produced. In some materials, heat can be

easily transferred (conductors), while in

other materials, heat can't pass through easily

(insulators).

What Are Insulators?

Page 12: Mathew Ang Sean Braganza Lenard Cheng Lawrence Chu Ethan Cu Brian De Guzman Paul Gue Dwight Ong Marc Ong Ryan Tan Mathew Yap TOPIC DEFENCE: WHAT MATERIAL

Not all materials can easily allow heat to pass through, and these are

called insulators. Materials with

molecules far away from each other are better insulators because the vibration can't easily

reach other molecules.

Where Do We Use

Insulators?

Page 14: Mathew Ang Sean Braganza Lenard Cheng Lawrence Chu Ethan Cu Brian De Guzman Paul Gue Dwight Ong Marc Ong Ryan Tan Mathew Yap TOPIC DEFENCE: WHAT MATERIAL

We use insulation so that we can make our own lives easier and safer. It makes our lives easier

because it lessens the cold entering our body. We can also use insulators when we want to keep materials warm for a long period of time. For example, we

wear jackets so that we can keep ourselves warm. We can also use insulation as cooking materials. An example can be

the handles of different pans so that we won't get burned.

Polyester

Page 17: Mathew Ang Sean Braganza Lenard Cheng Lawrence Chu Ethan Cu Brian De Guzman Paul Gue Dwight Ong Marc Ong Ryan Tan Mathew Yap TOPIC DEFENCE: WHAT MATERIAL

- made from polymers

- human-made- not easily affected

by mold and by other biological

substances- very strong, easily dried, and stays in

shape

Silk

Page 20: Mathew Ang Sean Braganza Lenard Cheng Lawrence Chu Ethan Cu Brian De Guzman Paul Gue Dwight Ong Marc Ong Ryan Tan Mathew Yap TOPIC DEFENCE: WHAT MATERIAL

- made from silkworms

- first made here, in China

- known for its strength, softness,

and insulating properties- expensive

compared to the others

Cotton

Page 23: Mathew Ang Sean Braganza Lenard Cheng Lawrence Chu Ethan Cu Brian De Guzman Paul Gue Dwight Ong Marc Ong Ryan Tan Mathew Yap TOPIC DEFENCE: WHAT MATERIAL

- one of the oldest types of cloth

- produced from farming and

harvesting cotton plants

- cheap compared to the other types

of cloth- worn by the

higher and the lower class

Problem

Page 26: Mathew Ang Sean Braganza Lenard Cheng Lawrence Chu Ethan Cu Brian De Guzman Paul Gue Dwight Ong Marc Ong Ryan Tan Mathew Yap TOPIC DEFENCE: WHAT MATERIAL

Which of the 3 materials (silk,

cotton and polyester) is the best insulator of

heat?

Hypothesis

Page 28: Mathew Ang Sean Braganza Lenard Cheng Lawrence Chu Ethan Cu Brian De Guzman Paul Gue Dwight Ong Marc Ong Ryan Tan Mathew Yap TOPIC DEFENCE: WHAT MATERIAL

Polyester is the best insulator out of the 3 materials

because of its complex

ingredients.

Procedure

Page 33: Mathew Ang Sean Braganza Lenard Cheng Lawrence Chu Ethan Cu Brian De Guzman Paul Gue Dwight Ong Marc Ong Ryan Tan Mathew Yap TOPIC DEFENCE: WHAT MATERIAL

STEP 1: Fill three 500ml bottles to the brim with hot water. (same

temperature)

STEP 2: Insert the 3 thermometers in each of the bottles, to check if the temperatures are the same.

( remove them if your already sure of their temperature)

Step 3: Wrap each type of cloth (cotton, silk, and polyester) outside of each bottle. Wrap them once.

STEP 4: Check the temperature of the set-up after an hour* and see

which water temperature decreased the most/least.

*use the stopwatch to time the experiment

Variables

Page 35: Mathew Ang Sean Braganza Lenard Cheng Lawrence Chu Ethan Cu Brian De Guzman Paul Gue Dwight Ong Marc Ong Ryan Tan Mathew Yap TOPIC DEFENCE: WHAT MATERIAL

Independent Variable: the different types of cloth

Dependent Variable: temperature of the water

after the experiment

Controlled Variable: - initial temperature of the

water- kind of bottle

- room temperature/location- time taken for the

experiment- amount of water

- the number of coil of these types of cloth to their

assigned bottle

Proposed Data

Presentation

Page 37: Mathew Ang Sean Braganza Lenard Cheng Lawrence Chu Ethan Cu Brian De Guzman Paul Gue Dwight Ong Marc Ong Ryan Tan Mathew Yap TOPIC DEFENCE: WHAT MATERIAL

A bar graph shall be used in this experiment.

With it, the temperatures of these 3

types of cloth will be seen obviously as which type of cloth is the best and worst insulators.
