Air Weight Science Project

The Importance of Weight on Air. Science Fair Projects for Air. Experiment on how to calculate the weight and mass of air.

Examining the Science of Air in Mini Science Project with Ideas!

For many centuries men who experimented with the problem of keeping a body heavier than air moving through it as a bird flies were the objects of ridicule and derision. Only so short a time ago as 1905, the first successful flying machine was invented by Wilbur and Orville Wright of Dayton,
Ohio.

Now, after invaluable service in the Great War, the air plane in a highly perfected stage has crossed the Atlantic Ocean. It has crossed our continent, a distance of 3000 miles, in 25 hours of actual flying time. One of man's greatest ambitions has become a reality, and without doubt the future holds further achievement in the development of the airplane as wonderful as that of the last few years.

Science Fair ProjectIdea 1: How does an airplane stay in the air?

The study of the kite may help us to understand the airplane.Is it possible to fly a kite on a day when there is no wind?

In starting to fly a kite, does a boy run with or against thewind? Is running necessary to start the kite on a day
when a strong wind is blowing ? What happens if the stringbreaks? What is the purpose of the tail of the kite? As
a result of a consideration of these questions, it will be understood that a plane or flat surface, if held at the proper angle, is kept up by the force exerted by the air in motion.

That air in motion has great force, is well known to us.The destruction caused by a severe wind is sufficient proof of this. We are also familiar with the fact that even when there is no movement of the air, the same force is exerted if an object is passing rapidly through the air. A ride on thefront seat of a street car or in a rapidly moving automobile convinces us of the force which may be considered to be exerted either by the moving body or by the air.

The airplane with its light, high power engine is ableby means of its propellers to attain great speed through the air. The planes may be so controlled that they present theproper angle to the air.The same force is exerted if the
machine is moving 75 miles per hour, as if the machine were stationary and the air were moving 75 miles per hour. Itwill thus be seen that the airplane remains in the air for thesame reason that a kite remains in the air.

Science Fair Project Idea 2: Does Air have Weight?

As the propeller of theairplane drives the machine through the air very much asthe propeller of a boat drives it through the water, air
seems to be a substance, just as water is. If this is true,it should have weight. Weight is the measure of the pull of the earth (gravity) upon particles composing variousseems to be a substance, just as water is. If this is true,it should have weight. Weight is the measure of the pull
of the earth (gravity) upon particles composing various materials. The weight of a book is the measure of the pull of the earth upon the book. If we drop it, it falls or is pulled toward the center of the earth. How may we discover that air has weight ? The following experiment has been tried many times.

Science Fair Project Experiment: I can calculate the weight of Air!

Weigh carefully a strong flask ; then by means of an air pump remove the air from it and weigh it again. What is the result?

That air has weight, may also be shown by blowing up basket ball or football until it is full and then weighing it,
and after allowing the air to escape, weighing it again.

Careful weighing has shown that one cubic foot of dry air t sea level and at the freezing temperature (of water) weighs about one thirteenth of
a pound. Calculate approximately the weight of the air in the school-room ; in your bedroom, etc.
