Hello! This week in science I learned some basic sketching stuff like shading and accuracy. I watched five videos on that subject then I also learned about making 3d objects like a cup or a house. I also learned how drawing can be expensive and you need all of these things that can be expensive like a modeling clay eraser is a little weird to me. There is even plastic erasers how do they even work? There also all of these different tools that don’t make sense to me drawing is way more complicated than I remember it being That’s my summary for this lesson.

RPC History 4 Lesson 80
Hello! Here is my assignment from Mr.Livingston Summarize each of the inventions you studied this week and how they impacted history. Also, explain the most interesting thing you learned this week, and why.
The Four inventions I learned about where Chess, The Erebus, The Printing Press, and the Mainspring.
Chess. The history of chess goes back almost 1500 years. The game originated in northern India in the 6th century AD and spread to Persia. When the Arabs conquered Persia, chess was taken up by the Muslim world and subsequently, through the Moorish conquest of Spain, spread to Southern Europe.
The Erebus. HMS Erebus was built by the Royal Navy in Pembroke Dockyard, Wales in 1826. When her career as a bomb vessel came to an end, Terror became a ship of exploration. She ventured north to the Arctic in 1836, under the command of George Back, where she suffered heavy ice damage in the aptly-named Frozen Strait.
The Printing Press. Goldsmith and inventor Johannes Gutenberg was a political exile from Mainz, Germany when he began experimenting with printing in Strasbourg, France in 1440. He returned to Mainz several years later and by 1450, had a printing machine perfected and ready to use commercially: The Gutenberg press.
The Mainspring. Mainsprings appeared in the first spring-powered clocks, in 15th-century Europe. It replaced the weight hanging from a cord wrapped around a pulley, which was the power source used in all previous mechanical clocks. Around 1400 coiled springs began to be used in locks, and many early clockmakers were also locksmiths.
And that’s it hope you enjoyed!
