Stars and Wishes . . .

Star: I've gotten good marks in Math, E.L.A, Social Studies, but I need to improve in Science.


Star: My stuff is all organized so I never lose things but my locker's a mess!

My Wish: I want to organize my time more wisely so that I have my assignments and projects done sooner (that way I don't have to go crazy a day before the due date) so I have more free time.

Technological Discoveries!

Today I visited the following blogs: Little Ox, Bub's Baluba Blog, Jenna's Blog, Chelsea's Creative World, and Sara's Site of Stuff.


At Little Ox I learned that paper was invented over 2000 years ago by Ts'ai Lun in China. People back then would sometimes pound rags, roppes, and even old fishing nets into pulp to make good paper-making fibres. They also used the hemp plant or the inner bark of the mulberry tree for fibre.


At Bub's Baluba Blog I learned that flat glass mirrors were invented in 1291 by an exclusive group of artisans. These new glass mirrors gave clear and undistorted reflections so that people could see themselves more clearly.


At Jenna's Blog I learned that glasses were invented in Italy around 1281 by Salvino D'Armate.


At Chelsea's Creative World I learned that the pocket watch was invented in the 16th century (1510) by Peter Helein, a master locksmith who's from Nuremburg, Germany.


At Sara's Site of Stuff I learned that the pencil was invented 1795 although graphite was discovered 1564 in Borrowdale, England. The wooden pencil was invented by Nicholas Jacques Conte.

The Caravel



The caravel (a light sailing ship) was invented in the late 1400s by the Portuguese. They were built to explore along the West African Coast and into the Atlantic Ocean.  It was an improvement of older ships and could sail very fast and well into the wind. Caravels were smaller and lighter then the later made Spanish Galleons (which were made in the 1500s). The ship’s thick planking on the hull replaced thinner and less adequate planking. They were broad-beamed ships that had two or three masts with square and triangular sails (which are called lateens). Caravels were about 65 feet long and could carry lots of cargo (around 130 tons)
