Science:Does air have weight?

On the 29/10/13 our class did a science experiment on air and if it has a weight and it does. This is something on how air does have weight.  Hope you enjoy reading this. :)

Does air have weight?

Equipment: Ruler
                   2 newspapers, or one

Prediction: Q. Does air have weight?
No, air does not have weight because if it did, we would be carrying air.
A. Air does have weight, it weighs 15 pounds per square inch.

Observe: When Ollie karate chopped the ruler it didn’t break because nothing was on the end of it, Mr M got a piece of newspaper and scrunched it up and placed it on the ruler. This time the when Ollie karate chopped the ruler the ruler did not snap but the scrunched newspaper went into the air and floated down in 5 seconds. Mr M got newspaper and instead of screwing it up, he flattened it and placed it on top of the ruler. Now when Ollie karate chopped the ruler it snapped, why you say, well if you want to now read my explanation below.

Explain: The ruler broke because Mr M had flattened the newspaper , and while he was doing that air was coming out causing the air to push down onto the newspaper and the ruler would eventually break or snap. This sometimes failed because the newspaper wasn’t flattened enough.

Whoa, fascinating.

Fire the catapult!

  1. Awesome post Tyrone, it was cool how the ruler snapped when the newspaper was flattened. I didn't think air had weight either. Keep up the great posts Tyrone.
