Essay #8 History of Inventions
Hello, in today’s lesson I will be talking about how some small inventions changed the world.
I’ll let you have a short little guess about one of the things I’m going to talk about today (before you read further please guess). If you guessed “soap,” you are correct. I will be talking about how soap had a big impact on the world, it may be small, but it has big impact.
How do you think we used to wash ourselves in the old days? The Romans used oil, they put it on their body and then scraped it off with a metal tool, but that’s not how we do it today. Today we use soap. The first soap we recorded in history was made by a man named Galen in the year 200 A.D. He used vegetable oil, animal fats, and lye and he cooked them into soap. You may be asking yourself why is such a small invention important? This small invention is important because before it was actually invented, we got sick, a lot and when I say a lot I mean we had the plague. Soap not only removes dirt but it also kills unwanted germs on your skin.
Next I’ll be talking about the wheelbarrow! Let’s get started. The wheelbarrow helps us move heavy objects that we can’t lift without breaking our back, because nobody wants to break their back, oh my gosh I don’t even want to think of that, anyway, back to the wheelbarrow. So it helps you move heavy objects without hurting your back, it saves a lot of trips going back and forth and back and forth picking up those heavy objects I was talking about, whatever that will be. Zhuge Liang was credited for the invention of the wheel barrow in 31 A.D. in China. Just in case, if you don’t know what the wheelbarrow is, I’ll explain. It is a small hand push vehicle with one or two wheels. I think that the dump truck inventors were inspired by the wheelbarrow, because a dump truck is kind of like a big wheelbarrow on two axes and 4 wheels, and of course it has an engine too. I don’t know, that’s just my guess. What do you think?
And the last invention I’ll be talking about is the heavy plough. The heavy plough is quite an old invention. The first plough was a scratch plough, the scratch plough worked well in dry soil but not that well for hard clay. That’s where the heavy plough comes in. The heavy plough worked well on hard clay, and it was used initially in northern Europe, where the soil was hard and though to break to plant seeds for crops. The heavy plough changed a lot from a normal plough to a four wheeled 10 ploughs machine, for industrial farming. This allowed more food to be grown and for more people to be fed, but it also compromised the quality of the food, as with industrial agriculture, many pesticides and chemicals started to be used on the soil.
Thank you for reading this article. I hope you have a nice day or night depends on whatever time zone you’re in when you read this. Can you guys think of a small invention that changed the world? Bye:)
