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

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.

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

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.
-
8/9/2019 Air Borne Vehicle
9/27
Build air chamber.
Fill the upper balloon with Helium gas.
-
8/9/2019 Air Borne Vehicle
10/27
Fill the balloon with atmosphere air.

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:
-
8/9/2019 Air Borne Vehicle
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.
-
8/9/2019 Air Borne Vehicle
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.

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.
-

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.

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.
-
8/9/2019 Air Borne Vehicle
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.
