This week I learned about the Light Switch, the Skyscraper, the Dishwasher, and Electromagnetic Waves.
The Light Switch is a switch that turns on or turns off a light. When one flips the switch up, it connects the wires causing the light to turn on. The benefits of the Light Switch is that it allows people to turn lights on and off without having to remove the light bulb.
The Skyscraper is a very tall building. In the late 1800s Skyscrapers were about ten to twenty stories tall, but now it is about forty to fifty stories tall. Skyscrapers are made out of steel and concrete to make it very sturdy. Other inventions like the safety elevator and the steam shovel, to help build a sturdy foundation, also helps to make the Skyscraper possible. The Skyscraper impacted history because it takes less space to build a Skyscraper which means more people can live in the city.
The Dishwasher is a box that one puts their dishes in to clean the dishes. Before the Dishwasher it would take a long time to wash dishes. It changed history because using the Dishwasher frees up a lot of time and gets rid of the harmful bacteria on the dishes
Electromagnetic Waves travel at the speed of light and can come in the form of light or on radios. The benefits of the Electromagnetic Waves is that we can have radios, phones and computers and TVs.
My favorite invention this week is the Dishwasher because it helps to wash the dishes and gives people more time to do other things..
