This week I learned about the Diesel Engine, the Mousetrap, the Radio, and the Semi-Automatic Shotgun. I will explain how each of these inventions impacted history.
The Diesel Engine uses diesel oil to power it. When the piston pumps it compacts the air, which heats it up, it then ignites the diesel oil forcing the pistons down. The Diesel Engine impacted history because it is more efficient then the steam engine which means cargo ships can hold more cargo and less coal to power the ship.
The Mousetrap is a device used to trap mice and other small rodents. When pressure is applied to the trigger, the spring expands causing the jaws to slam shut catching the mouse inside. The benefits of the Mousetrap is that mice and rats can be caught easily without having to touch them, which could give people diseases
The Radio is a device used to listen to music and broadcasts, but it can also be used to talk to other people using things like walkie-talkies. The Radio impacted history because we can listen to music without going anywhere and we can talk to people from far away.
The Semi-Automatic Shotgun is a gun that one only has to load the bullets once and pull the trigger to fire each of the bullets and then reload the bullets. The Semi-Automatic Shotgun changed history because it made it a lot easier in wars because one didn’t have to stop every shot to reload.
Finally, my favorite invention this week is the Radio because I love listening to music and long car drives are made easier by listening to music which could not be possible without the Radio.
