REVOLVER(GUN)Lever

MammothG6N

The problem being solved People needed something better than

sword Guns came to replace swords Guns do more damage than swords Easy to carry and effective Change the size of force Change the direction of force

How science solves the problem

Levers changes the size of force Levers changes the direction of force Gunpowder changes the force size more Before guns, people used swords/knives MA of gun more than sword’s Guns create more damage than

swords/knives

Development of the Technology

Invented in 14th century by Chinese Chinese guns had no simple machines Europeans created guns with simple

machines Europeans’ guns did more damage European guns change direction/size of

force Revolvers later developed for easy carry

How well science solves the problem

The technology creates lots of damage MA of it is greater than sword’s Simple machines allowed this to be

possible guns are smaller than swords Easier to carry than swords Simple machines allowed this to be

possible

How well science solves the problem

Sometimes the mechanics can be broken Sometimes it is not water proof It is hard to fix yourself Swords have no mechanics to be broken It is waterproof You can fix a sword yourself

InteractionsLife: Guns effect life a lot People are murdered/assasinated with
