AS OLD AS WRITING

Managing your learning: Time lines The time line provides a study tool that allows you to organize information that is presented chronologically. Time lines would be effective to use in classes in which you present historical, biological and other developments. To make the order clear and to show the sequence of events, we mention dates and time, and we also use various links and connectives.

Written communication has been the centre of civilization for centuries. However, putting thoughts down in a written form wasn’t always easy or practical. Paper has a long history, beginning with the ancient Egyptians and continuing to the present day. It has largely survived the test of time but now it is facing a new challenge from its electronic equivalent. A particularly fruitful way to look at the evolution of paper is to study how it has changed over time.

3500 BC	Sumerians use cuneiform* alphabet, pressed in clay with a triangular stylus. Clay tablets were dried and/or fired for longevity. Some even had clay envelopes,' which were also inscribed.
3000 BC	Egyptians created Papyrus, a material made from thinly cut strips from the stem of Cyprus Papyrus plant.
2400 BC	Date of the earliest surviving papyrus scroll with writing.
200 BC	Both Greeks and Romans used wax tablets, framed and backed with wood, for note taking, orders, correspondence, and other temporary communication.
197-159 BC	In the Middle East, near Pergamum, large herds of cattle were raised for skins to be made into what we now call 'parchment.' It was the most popular material for manuscripts until the 12^th century.
105 AD	Papermaking was invented in China by Ts'ai Louen. Material used: plant bark*, discarded cotton and old fishnets.
300-700	Secret of papermaking crept out from China to Vietnam, Nepal, Korea and Japan.
	First papermaking mill was established in Spain
1300C.	Papermaking reached Southern Italy, where, until quite recently, some of the oldest handmade paper mills* in Italy were operating in the Naples area.
	Johann Gutenberg invented the printing press.
1700 C.	Tremendous increase in papermaking led to a serious shortage of raw materials.
	Saxon Keller invented a ground wood pulp*.
	Mellier Watt patented a chemical pulp.
Late 18-th	Nicholas Luis Robert created a machine that could produce a seamless length of paper. Paper production became industrialized with the advent of steam-driven paper making machines.
1950s	New material and fillers were used, new processed chemicals and dyers* were developed.

Get real

Search the Internet and/or any popular science magazines to find information on the transformations of any device or tool in your field of study. Create a timeline to demonstrate its evolution.

Writing

Managing your learning: Narrating and reporting Past tense is common. Chronological order is also common, but when we are writing about past events, it is necessary to be explicit about the order in which things happened. To show the sequence of events use dates and time as well as time/sequence expressions.

Write a paragraph of about 100-150 words describing the evolution of the chosen device/tool. Give reasons for your choice. Make use of the timeline help box and Tool box.
