OBJECTIVE:

D esign a model of an air borne vehicle that made

with aluminum cans that can fly for at least 3

minutes and heat the target.


3/22

HYPOTHESIS:

Use of suitable lighter gas to carry the air borne

vehicle for more then 3 minutes and hiat the target

when the atmosphere air is released.

PROCEDURES:

LIST OF MATERIALS:

Aluminum cane Balloon Thinned M anila card S tand (target)

Substances

H elium gas Balloon gas


5/22

P RELIMINARY O P ERATIONS

Before starting the experiment it is important to perform the preliminary

operations described here.

M aterials: Aluminum cans Balloon with

H elium gas Air chamber

Atmosphere air


6/22

M ethod

Build air plane using aluminum cane.


7/22

Build air chamber.


8/22

Fill the upper balloon with H elium gas.


9/22

Fill the balloon with atmosphere air.


10/22

S tep 1: Building an Airplane

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

M aterials:

Two aluminum canes Glue Scissors

Gloves M etal ruler

M ethod:

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

of the airplane.

- Cut the upper part of the cans.

- J oin the cans.


11/22

S tep 2: Filling the H elium gas.

The H elium 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 the airplane.

M aterials:

Balloon (Gred G-20) 100 l of H elium gas Valve (40 gm)

M ethod:

Fill the balloon with approximately 100 l of H elium gas. Tight up the valve at the

mouth of the balloon to control the amount of H elium gas. Connect the balloon with

the airplane using thread.

- H old the balloon carefully during filling

the H elium gas.

- Carefully tight up the valve.

- Connect the balloon with the airplane.


12/22

S tep 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.

M aterials:

N ylon thread Scissors M etal stand

- Tied with nylon thread.

- Tied with metal stand.


13/22

S tep 4: Preparation of Air Chamber

Fill the balloon with the atmosphere air. M aterials:

Insert the balloon into the air chamber. M odel of air chamber Balloon

Pump

M ethod:

H old the balloon carefully and fill it with atmosphere air.

S lowly insert the end of the balloon into the air chamber without tight up the mouth

of the balloon.

H old the mouth of the balloon for the next step.

- Fill the balloon with atmosphere air.- Insert the balloon into the air

chamber.


14/22

S tep 5: H it The Target

Hold the balloon gently and release the atmosphere air and observes.

M aterials:

Bull eye

M ethod:

H old the mouth of the balloon and observe the position of airborne vehicles.

Gently release the atmosphere gas and observe the movement of the vehicle.

- Release the atmosphere air.

- O bserve the position of the air

borne vehicle.

LIST OF VARIABLES

M anipulated variable:

Atmosphere air

Constant variable: The weight of airplane 43 gm

Weight of the valves 40 gm

Weight of the empty Balloons 20 gm Length of the airplane 250 mm

Length of the air chamber 300 mm

D istance between airplane and air chamber 65 mm

D istance 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 obtain better 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.

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.
