in 1980's when I was young, the story books I had were hard cardboard books with colour and lots of drawings. I loved reading. At the time it showed that daily life was simple and stories were important for children to read and listen to.

In 1990's my little cousins had story books that had different textures so the children could touch the book and felt what it was. They even had music and someone's voice was recorded in the book. It was soooo interesting. It showed that daily life was changing and children were introduced to different ways to read stories where you can hear and feel things when you read the book.

Now story books can be on the computer, in the library, on your phone. This shows that daily life has changed. People use more electronics now and so the storybooks are also available on these electronics for children to read. You have lots of books on one phone instead of many books in your room taking up space.

The 1800s was a great century for advancements in medicine, social revolution and, of course, pens.

The big thing in the 1800s was the fountain pen, which used a steel point and an inkwell. The late 1800s brought us a fountain pen with its own self-contained ink, which meant not having to dip the pen in an inkwell.

Before the steel pen points were invented, writers would use quills, reeds or still brushes as pens.

\

The famous ballpoint pen was patented by John H. Loud, an American inventor, in 1888. The pen didn't see much use until World War II, but pilots started using ballpoint pens because they wouldn't leak at high altitudes. The pens became much more popular after the war, and are a popular choice today.

Thses facts about pearls include information about the invertebrate animals that have the ability to take a piece of sand and turn it into one of the most valuable things any animal creates. Pearls are made by a shelled animal classified as the bivalve mollusk. Learn about these mollusks and some facts about pearls they are able to make.

Rare high-quality pearls have become as valuable as precious gemstones. Pearls are worn in a variety of ways such as a string of pearls for a necklace or bracelet.

Facts about Pearls

Pearls form inside living bivalve mollusks.

Bivalve mollusks have a shell with two parts and a muscle that allows the mollusk to open and close the shell. Oysters are the most common mollusk to naturally make pearls, but mussels and clams can also make pearls.

The mollusks feel an irritation caused by sand or other material. In response, the mollusks form material around the sand. It grows larger and larger as new coatings are applied.

The coating material that makes up a pearl is known as nacre or "mother of pearl". It is material like calcium carbonate, which is very tough. Like all calcium carbonates, pearls can be destoyed by acid.

Mother of pearl is also the material that coats the inside of many oyster and clam shells.

When this process occurs naturally, the result is a natural pearl, which is very valuable.

Pearls are sold by the karat. The cost is based on the size, shape, color, origin, perfection and luster (if it is shiny). A large, perfect natural pearl from the South Pacific is worth over $30,000.

Most bivalve mollusks make pearls, however, not all pearls are attractive. Pearls occurring naturally are rare.

The largest supplier of pearls is Lake Biwa in Japan.

Pearls that grow attached to the animal's shell are called blister pearls.

Cultured pearls are grown with the help of people. A person places a tiny piece of glass or a plastic bead inside the mollusk. The cultured pearl then takes about 4 years to grow.

Cultured pearls are valuable, but not as valuable as natural pearls.

With advancements in plastics, people can now make "fake pearls", which look real to an inexperienced person.
