INTRODUCTION:

e wondered how people first tried to fly, what a blimp is, or how a heavy airplane can

stay up in the air. This Science Fair program urged us to find the answers to these

questions. People make wings of feathers and tried to fly like birds. They attached their

homemade wings to their arms and jumped from high places. Usually they were killed

or badly injured.

People who was brave tried to rocket through space. There was a great big explosion and lot of

smoke and he was never seen again. The first successful flying machine was a balloon built by

Joseph and Jacques Montgolfier in 1782. They watched and discovered that heat made balloon

rise. So the hot-air balloon was started to carry the passengers. But balloon flight cant becontrolled. Scientist use very big plastic balloons to gather weather information. Balloons carry

equipment to record temperature, humidity, air pressure, and wind speeds. If a weather balloon

breaks, the instruments it carries float back to earth in bright red parachute. Gradually human

improve the flying system they inventing a zeppelin. A zeppelin was a large dirigible. The first


5/27

zeppelin was built in 1900. It had cigar- shaped aluminum frame. Zeppelin trips flew across

the Atlantic Ocean. During the World War I zeppelins had another use. One hundred

zeppelins were built for war. After 803 feet zeppelin built and it was called Hindenburg. Also

it was the largest airship ever built. After the Hindenburg tragedy, hydrogen was never used inairship again. And zeppelins were never again manufactured. The mankind was tried to fly

through glider plane, hang gliding and more. The Wright Brothers invented the first safe,

successful airplane.

A science fair is basically a collection of many different science projects that are shown to the

public (27).

This event particularly productive for students because scientific activities require mental

discipline, clear ideas, organization in the collection of data and in their handling. They favor

the learning of objective and concise writing methods. Also, they incite the students lifetime.

Success in these activities spurs children on to continue in this path. These experiments even

reveal themselves to be useful in ones subsequent professional life.

Working on this Science Project has given us the unusual opportunity to take a closer look at

the natural world, and perhaps make a discovery. It has also given us an opportunity to meet

and learn from other young scientist as well as professionals from many fields.

7/27

Design a model of an air borne vehicle that made with aluminum

cans that can fly for at least 3 minutes and heat the target.

HYPOTHESIS:

When move helium gas is used it will carry the air borne vehicle for

more then 3 minutes and heat the target when the atmosphere air is

released.

PROCEDURES:

LIST OF MATERIALS:

Aluminum cane

Balloon

Thinned

Manila card

Stand (target)

Substances


8/27

Helium gas

Balloon gas

PRELIMINARY OPERATIONS

Before starting the experiment it is important to perform the

preliminary operations described here.

Materials:

Aluminum cans

Balloon with

Helium gas

Air chamber

Atmosphere air

Method

Build air plane using aluminum cane.


9/27

Build air chamber.

Fill the upper balloon with Helium gas.


10/27

Fill the balloon with atmosphere air.


11/27

Step 1: Building an Airplane

This operation is to make the air plane using the aluminum.

Materials:

Two aluminum canes

Glue

Scissors

Gloves

Metal ruler

Method:


12/27

Cut the upper part of the canes and join the two canes with glue to

make the body of the airplane.

Step 2: Filling the Helium gas.

The Helium gas is lighter than the atmosphere air. So it will help the

balloon to float in the air. At the same time it also will carry theairplane.

Materials:

Balloon (Gred G-20)

100 l of Helium gasValve (40 gm)

Method:

- Cut the upper part of the cans.- Join the cans.


13/27

Fill the balloon with approximately 100 l of Helium gas. Tight up the

valve at the mouth of the balloon to control the amount of Helium

gas. Connect the balloon with the airplane using thread.

Step 3: Connection with Balloon and the Support.

Tight the airplane with nylon thread.

Connect the air borne vehicle with the support to hold the air borne

vehicles position in the air.

Materials:

Nylon thread

Scissors

Metal stand

- Hold the balloon carefullyduring filling the Helium gas.

- Carefully tight up the valve.- Connect the balloon with the

airplane.


14/27

Step 4: Preparation of Air Chamber

Fill the balloon with the atmosphere air.

Insert the balloon into the air chamber.

Materials:

Model of air chamber

Balloon

Pump

Method:

- Tied with nylon thread.- Tied with metal stand.


15/27

Hold the balloon carefully and fill it with atmosphere air.

Slowly insert the end of the balloon into the air chamber without tight

up the mouth of the balloon.

Hold the mouth of the balloon for the next step.

Step 5: Hit The Target

Hold the balloon gently and release the atmosphere air and

observes.

Materials:

Bull eye

Method:

- Fill the balloon withatmosphere air.

-

Insert the balloon into theair chamber.


16/27

Hold the mouth of the balloon and observe the position of airborne

vehicles.

Gently release the atmosphere gas and observe the movement of

the vehicle.

LIST OF VARIABLES

Manipulated variable:

Atmosphere air

Constant variable:

The weight of airplane 43 gm

Weight of the valves 40 gm

- Release the atmosphereair.

-

Observe the position of theair borne vehicle.


17/27

Weight of the empty Balloons 20 gm

Length of the airplane 250 mm

Length of the air chamber 300 mm

Distance between airplane and air chamber 65 mm

Distance between base of an airplane with valves 300 mm

Responding variable

The position of airplane after the atmosphere air is released.

SAFETY MEASURES AND PRECAUTIONS

We have to implement many safety measures in completing the

experiments to minimize any untoward incidents and also to avoid

contamination of the experiment area. This is important to obtainbetter model of an air borne vehicle and improve our results. Some

of the measures include:

Very careful in handling apparatus like the scissors and aluminum

cans to avoid injuries to fingers.


18/27

Wore gloves when handling the aluminum cans.

Wear goggles during the experiment to avoid any substance or

materials from entering the eyes.

Always guided by elders during the experiment.

RESULTS:

We conducted this experiment in five steps and the diagrams are
