Most Important Inventions
Spectactles
An important advance in the science world came from the development of convex and concave lenses first used as vision correctors in about 1280, in Florence, Italy. These spectacles can be seen in paintings of Pope Leo X, who was often depicted wearing concave lenses to correct his vision problem of myopia, or near-sightedness. From the development of these lenses came development of the microscope and telescope, which will be discussed later.

Clock
In the beginning of the Renaissance time period, we can see the first portable clocks developed in Florenece, Italy, in 1410 by Filippo Brunelleschi, a famous architect. Before this time, mechanical clocks were large, fixed devices. The spring- driven clock made it possible to carry the time around with you.

Microscope
Another major development in the science world was the microscope invented in 1590 by Zacharias Janssen and his father in Holland. It was a compound microscope with two lenses. The microscope was used for viewing things too tiny to be seen by the naked eye. It used concave and convex lenses to bend light and greatly enlarge images.

Printing Press
A big development in writing and literature was the invention of the printing press. Invented in 1436 by a 39 year old German man named Johann Gutenberg, the printing press was a great improvement over hand-copying. Before the development of this time-saving and economical machine, monks had to hand copy everything. This time-consuming and tedious process made books and scripts extremely hard to come by, and astronomically expensive. Gutenberg used his printing press to put ink on hundreds of individual letters that could be combined in numerous ways to create a entire page of text. After this stage was completed, as many copies as desired could be rendered. However, to print a different page, the individual letters had to be completely rearranged. This great invention helped Gutenberg reach his greatest achievement of the first mass-production of the Bible, which he published in 1456 in Mainz, Germany.

Submarine
The submarine was invented in 1624 by a man named Cornelius van Drebbel. However, Leonardo da Vinci drew out the basic concept of a submarine over one hundred years before. Drebbel, a Dutch inventor and engineer employed by the British navy constructed a leather- covered rowboat from which oars protruded through watertight seals. Drubbel's ship could stay underwater for a few hours, but it only went about fifteen feet under the surface.

Match
Fire - our worst enemy, our best friend - was difficult to create until Robert Boyle invented the match in 1680. Although fire could be made by rubbing sticks together or by striking flint to steel, this was a time consuming process. Boyle discovered that when phosphorus and sulfur were rubbed together, they would burst into flame. Boyle knew that this was not because of friction, but because of chemical nature of these two substances. Although convenient, Boyle's matches were not very safe, because sometimes they accidentally went up in flames while in a pocket. (Warm surprise!) With some improvements and a little fine tuning, this invention led to your modern safety match many years later.

Task: Poetry and Inventions
To conclude this lesson you will write a poem about one of the inventions above. The poem is at least 12 lines long and should be written with love. And before I forget to mention: You can do anything with the invention. Make it dance, talk or sleep, do its own thing or even weep. Just make sure the sentences rhyme. Also: upload it to your site in time!
Example poem:
You make my life so bright
When you're around with your spark
I will never need another light
Not even when I'm in the dark.
You make my days so warm
When you're around
I feel like I'm reborn
And without the slightest sound
You set my world on fire,
make me feel so hot and nice
You're thing that I desire;
You're a match from paradise
