History Essay – Lessons 81-85

This week I learned about two inventions and two historical figures. They are the mariner’s astrolabe, double-entry bookkeeping, Luca Pacioli, and Leonardo Da Vinci. My favorite historical figure from this week was Leonardo Da Vinci.

The first invention was the mariner’s astrolabe with four cut out holes. The mariner’s astrolabe was an innovation from the astrolabe. It was made to be an astrolabe that suited the ocean more than land.

The second invention was double-entry bookkeeping. It was a way of keeping track of your money and your worth. In that time, bartering was declining. There had to be a way of accounting for your valuables.

Luca Pacioli invented double-entry bookkeeping. Luca was best known for advancing the economy through double-entry bookkeeping. He lived during the 1400s and contributed to the Renaissance.

The last historical figure was Leonardo Da Vinci. Leonardo was a famous painter and made the most high-priced paintings ever. Although he couldn’t focus for a second, he was rather gifted. He was good at biology, geometry, chemistry, and was an inventor. Leonardo is my favorite historical figure because he made a lot of good things in his life… even though he could not focus for a second, just like me!

In History I learned about four inventions. They are chess, the arquebus, the printing press, and the mainspring. Chess is a game of strategy that began in India in the 6th century and is still played today. The second invention was the arquebus. It was a long gun being also a muzzle loaded firearm. It was used from the 15th to the 17th century. The third invention was the printing press. It was a machine designed to speed up the process of making books. It’s use grew rapidly from the 14th through the 16th century. The last invention was the mainspring. A mainspring is a spiral torsion spring of metal ribbon.

This Week’s Inventions

History Essay – Lessons 61-65

There are four inventions I learned about this week. We studied buttons, oil paint, the cannon, and the spinning wheel.

The first invention I learned about this week was the button. The button is a piece of plastic cut into a circle that has two holes. Its purpose is to keep clothing together tightly enough that it is hard to see the skin.

The second invention was oil paint. Oil paint is a type of paint that can be made from oils, eggs, snail slime and even pig snot. It is mixed with pigment, and it allows for us to paint with more detail than earlier paints from before the 15th century.

The third invention I learned about this week was the cannon. The cannon is a weapon used to break walls and destroy whatever they target. The cannon helped people destroy walls and protect walls. We can trace back the first cannon to China, but it has been used by many counties.

The last is the spinning wheel. The spinning wheel is a table with a wheel that is connected to a piece of string that is spun to knit clothing together. It allowed for clothing to be made faster to sell or trade.

My favorite was the Cannon because every little kid loves things that destroy other things.

Important Inventions

History 4 – Lessons 56 – 60 Essay

This week I learned about four inventions: the Trebuchet, Distilled Spirits, the Vertical Windmill, and the Stern-Mounted-Ruder.

The first invention is the Trebuchet. The Trebuchet is a bigger catapult and instead of originating from the crossbow it originated from the sling. Its impact was being able to break walls easily, and defend castle walls. They also could be fired at targets that couldn’t have enough reach to hit them with crossbows.

The second invention was Distilled Spirits. Distilled Spirits are a strong type of alcohol like rum that could make you feel good if you don’t drink it too much. It’s impact on history was that it was used as a treatment for the plague “Black Death.”

The third invention is the Vertical Windmill. The Vertical windmill is a tall building with four sails. Its impact on history was that it produced electricity and made bread for the people who lived there.

The last invention was the Stern-Mounted-Ruder. It was a wooden paddle that attached to the under side of a boat and when you turn wheel it turns the rudder. Its impact on history was that you can steer the boat easily, which meant people could transfer goods to other continents, cities, countries, or even states! These inventions changed the world.

History Essay – Lessons 51-55

This week I learned about four important inventions, the winepress, the chimney, the ribbed vault, and universities. We are going to talk about what they are and their impact on history.

The first invention we learned about this week was the university. The first universities were built in 1070 AD. They are buildings that people go to to learn. They produced important scholars that advanced human knowledge and educated.

The second invention was the winepress. It was a basket that had a hydraulic press on top that squished grapes to get the juice. It helped promote the discovery of wines that did not spoil us so quickly.

The next invention was the ribbed vault. It was first made in churches in 1100 AD. These vaults had ribbed patterns on the bottom of a church ceiling. It made it so people could make churches longer and bigger and also made it so windows could be installed farther up on the wall.

The last invention was the chimney. It was found in a man’s home in the 11th century and was manufactured by the 13th century. The chimney was a clay mold that went from the ceiling to the floor and produced heat. The chimney kept people warm and people did not die so easily from harsh weather.

These inventions were very helpful to human kind. The winepress made better wine. Universities produced important scholars that advanced human knowledge. The ribbed vault made churches bigger and better. Chimneys saved lives.
