1. Explanatory Essay on a Study Tool: The Ballpoint Pen

Throughout my schooling years, I've always been inseparable from my school bag, books, pens, rulers... and among these study tools, the one I cherish the most is the ballpoint pen, an item that has been my companion for many years and will surely remain useful to me in the future!

Back in elementary school, I used a fountain pen and my handwriting was quite neat, but when I reached second grade, it caused me a lot of trouble. I had to write while listening to the teacher's lectures at a fairly fast pace, so the fountain pen couldn't meet this requirement. My writing was messy and smudged, which was very unpleasant! At that time, my father gave me a ballpoint pen with advice: 'try using this type of pen, hopefully it will be useful to you.' Since then, I have always used this type of pen and today I have the opportunity to look back and learn more about it.

The first ballpoint pen was introduced by a Hungarian journalist working in England named Laszlo Biro in 1938. What prompted him to invent this type of pen was his disappointment with fountain pens, which often tore paper, got dirty, required ink pumping, and frequently broke... On June 15, 1938, Biro was granted a British patent. Since the ballpoint pen was invented, it has been greatly improved to suit users and has become popular worldwide. Although they may differ in appearance, they all have a similar structure. The ballpoint pen has a core of solid ink, the tip of the core is attached to a small ball with a diameter of about 0.7 to 1 millimeter, which is considered the pen nib. When we write, the ink is printed on the paper thanks to the rolling movement of this ball, and the ink used for ballpoint pens dries very quickly.

People often overlook the familiar, everyday items around them. They may calculate how many kilometers one might travel in a lifetime or how long a person can hold their breath, but there's likely no statistic on the number of pens they use in their lifetime! A pen is like a human body, with its ink cartridge as its internal organs, the pen tip as its heart, and the ink as its blood, nourishing the body. The pen casing is like the body, limbs, and extremities... they need to be sturdy for the pen to be durable, function well, and provide comfort to the user. The exterior color and shape are like clothing, adding to the pen's aesthetic appeal. Whether important or trivial, every detail of the pen contributes to its entirety. Like a silkworm spinning silk threads silently supporting life, pens help in life quietly until their ink runs dry, then they're discarded coldly. Few remember their contribution!

Entering a new school year, pen manufacturers such as Ben Nghe, Dong A, Thien Long, Han Son... have introduced a variety of models, from simple to elaborate, such as click pens, twist pens, dual-color pens, tri-color pens... to meet the needs of users. While male students simply clip their pens to their shirt pockets, many female students like to 'dress up' their pens with drawings, cute shapes on the body or the pen tip adorned with cute little animals... Thus, these ballpoint pens follow students to school, helping them preserve valuable information, knowledge conveyed by teachers with all their hearts!

There are pens with a simple, rustic appearance, but there are also pens that are gold-plated and shiny. Looking at a pen, one can tell each other's 'class,' but looking at the handwriting, one can judge each other's personality or assess each other's level. 'Fine feathers make fine birds,' a good pen, no matter how good or expensive it is, is just an accessory if it falls into the hands of an empty-headed person! A pen is an inanimate object, so it doesn't create meaningful sentences on its own, but if in the hands of a diligent, studious owner, it will produce good essays, beautiful writings. To become the 'master' of these pens, students need to cultivate habits of clean notebooks, neat handwriting, and always strive for knowledge... turn them into a close friend, a strong arm in learning, my friend!

Along with books, notebooks... the ballpoint pen is an important learning tool for students, so we need to take good care of our pens. After use, always cap the pen immediately to prevent the pen tip from being damaged, the most important part of the pen. Especially, always store the pen horizontally to ensure the ink flows evenly, without clogging. Some types of ballpoint pens can replace the ink refill when it runs out, and I'd like to share a small tip with you: if the ballpoint pen is left unused for a long time and the ink dries out, don't rush to throw it away, just soak the pen refill in warm water for 15 minutes... your pen can be restored!

'Green and red pencils.
I sharpen both ends.
I try two colors.
Refreshing green, vibrant red.
I draw the village.
Green bamboo, green rice.
The winding river flows.
A cool green line'

Educational tools are essential items that serve our learning needs. Alongside rulers, ballpoint pens, compasses, or colored pencils, pencils also hold an important position in facilitating our learning.

Pencils have been invented very early. In 1564, the type of graphite, called graphite, was used in England. In 1662, in Germany, the first pencil was produced. In 1795, Nicolas-Jacques Conte invented the modern pencil, which has been widely used since then.

Exposition on the pencil

A traditional pencil is composed of two parts. The first part is the core made of graphite, and the second part is the casing, made of wood or compressed paper. Modern pencils have graphite cores, designed with a clickable cap, and the casing is made of plastic, or the graphite tips are continuously connected...(Continued)

3. Exposition on an Educational Tool: The Ballpoint Pen

The student life is intimately tied to various tools, stationery, among which are some extremely important ones primarily serving in the realm of learning: books and rulers. Before the advent of various types of ballpoint pens, fountain pens as we have today, the image of students carrying a ballpoint pen and a bottle of purple ink was one of the most beautiful and memorable memories of school days.

The fountain pen, also known as a fountain ink pen or ink pump pen, embodies simplicity in design. Originating from ancient times, it was ingeniously crafted by an Egyptian calligrapher named Al-Muizz Lideenillah to enhance his calligraphy skills. Over time, it gained popularity worldwide, especially in Western countries. In Vietnam, a nation steeped in traditional culture, quill pens were prevalent until the early 20th century when fountain pens were introduced. It took nearly 50 years for the populace to widely embrace fountain pens for academic and clerical tasks.

Exposition on the Fountain Pen

The fountain pen boasts a relatively simple structure comprising a pen nib and a ink feed mechanism encased within its outer shell. Historically, fountain pens predominantly featured ink reservoirs made of rubber. To refill the ink, one would remove the outer casing and immerse the nib into the inkwell... (Continued)

4. Exposition on Study Tools: Eraser

In today's education landscape, there exists a plethora of tools and aids to support students' learning endeavors. Among these essentials such as rulers, pens, books, and notebooks, one ubiquitous yet indispensable item found in every student's pencil case is the humble eraser.

You may not know that the first erasers in the world had their origins in bits of bread. These earliest erasers made from bread bits emerged in the 1770s. Despite their inconvenience due to crumbling and mold, they were essential for erasing graphite marks. Overcoming the limitations of bread erasers, English engineer Edward Nairne successfully invented the eraser as we know it today.

Exposition on the Eraser

A typical eraser comprises two parts: the eraser itself and its outer casing. The outer casing, usually made of stiff paper, is adorned with branding similar to packaging of other products. Modern erasers are predominantly made of rubber compounds, but there are also expensive ones made of vinyl blends or cheaper ones made from synthetic fibers derived from soybeans. Depending on the eraser material, they exhibit different characteristics, and manufacturers can produce erasers in various colors such as blue, purple, yellow, red, etc... (Continued)

6. Exposition on a Study Tool: The Ballpoint Pen

In our daily lives, there is an item we use regularly but often overlook – the ballpoint pen. Today, I will introduce this essential tool to you.

Despite our widespread use of ballpoint pens, few are aware of their origins. The first patent for a ballpoint pen was filed by an American inventor named John Loud in 1888, although it was never commercially exploited. It wasn't until 1938 when a Hungarian journalist named Laszlo Biro, frustrated with fountain pens, invented a ballpoint pen that used quick-drying newspaper ink. On June 15th, he was granted a patent by the United Kingdom. Since its inception, the ballpoint pen has continuously been improved to meet consumer demands. Renowned brands such as 'Ba', 'Hoover', 'Xeros', and notably 'Bic Cristal' have contributed significantly to its evolution. Since 1940, Biro's birthday on September 29th has been celebrated as Inventors' Day for the ballpoint pen. Now, do you know who invented the ballpoint pen and when it was invented?

To understand the ballpoint pen better, let's discuss its construction. If you were to dismantle your ballpoint pen, you would find a refill inside. This refill contains a thick ink. At the tip of the pen, there is a very small ball, typically ranging from 0.7 to 1 millimeter. This ball moves as you write, transferring ink onto paper quickly and efficiently. There are various types of ballpoint pens, made from different materials such as hard plastic or metal. Disposable plastic ones are commonly used and discarded after the ink runs out, while metal ones, although more expensive, can have their ink refilled and be reused multiple times. The pen caps come in various forms, either removable or retractable. Some have a twist mechanism, while others have a clicker to extend the pen nib. Additionally, there are many other variations of ballpoint pens, such as twist caps, etc.

Every year, as the new school year approaches, Vietnamese pen manufacturers like 'Thien Long' and 'Ben Nghe' introduce numerous new models, ranging from simple to elaborate, to meet consumer demand.

To use a ballpoint pen for an extended period, one must understand how to use and preserve it properly. When writing, the pen should be held at an angle of 40 to 60 degrees, avoiding laying it flat. After use, the cap should be immediately replaced to prevent damage to the pen tip. Since the pen tip is the most crucial part, if it becomes damaged, the pen will become unusable. The pen should always be stored horizontally to ensure ink flow in the refill. Here's a tip: if the pen has been left unused for a while and the ink has dried up, don't rush to discard it. Instead, soak the pen in lukewarm water for ten to fifteen minutes. Your pen will be restored.

As we all know, the ballpoint pen has become a familiar part of our lives. It's both inexpensive and convenient. We see it on desks, in pockets, or in cars—anywhere writing is needed. Additionally, ballpoint pens are often used as free giveaways for advertising purposes. Recently, there has even been the emergence of ballpoint pen tattoos...

The significance of the ballpoint pen for our students is immense; we seem to use it every day. The ballpoint pen may seem insignificant, but it not only produces meaningful words but also, when used diligently, can create excellent essays and beautiful writing. To become a master of the ballpoint pen, our students need to keep their notebooks clean, practice beautiful handwriting, and exchange knowledge. Turn your ballpoint pen—a seemingly trivial object—into an essential tool, a reliable assistant in your academic endeavors!

7. Exposition on a Study Tool: The School Bag

Throughout their school life, students always accompany books, notebooks, pens, rulers, and consider them indispensable. Among these study tools, the item used to carry these essentials is the school bag—a companion that has been with me for many years and will undoubtedly continue to be useful in the future!

The school bag is widely used in both academic and daily life. It's certain that the school bag can be included in a long list of important human inventions. The invention of the school bag is credited to an American in 1988.

In terms of construction, the exterior features are most noticeable: the bag flap, carry handles, bag cover clips; some bags have shoulder straps, while others have small wheels for pulling on the road... Internally, there may be one or multiple compartments used to store books, study materials, raincoats, wallets, or even food and drinks...

The process of making a backpack involves several main stages: material selection, processing, sewing, and assembly. There are many types of materials suitable for users' needs: corduroy, canvas, crocodile leather, faux leather,... Regardless of the material used, the backpack must be sturdy, as it has to carry heavy books. In addition, the design of the backpack must be suitable. For example, boys often wear backpacks with straps to one side for a stylish, dynamic look. Girls wearing traditional ao dai tend to carry the backpack in front for a gentle, graceful appearance. Children wear backpacks on their backs for easy running, jumping, and playing. Along with colors, there are currently many types of backpacks with diverse, eye-catching images suitable for different age groups.

Exposition on the School Bag

Some tips for using the backpack correctly: the backpack should not exceed 15% of your body weight when worn. Place the heaviest items inside the backpack (the part against the back). Stack books and study materials so they don't shift. Make sure that the items in the backpack are necessary for daily activities. For backpacks with two straps, avoid wearing them loosely on one shoulder, which can cause spinal misalignment. For backpacks with only one strap, alternate shoulders to avoid spinal misalignment. When buying a backpack, choose straps with padding, foam, or fabric,...

Nowadays, there are many famous brands such as Miti, Samsonite, Tian Ling, Ling Hao,... popular everywhere from Taiwan, Japan, South Korea,... But no matter how beautiful and durable they are, they gradually deteriorate over time if we don't know how to take care of them, such as throwing them around whenever we feel upset or throwing them away when we're having fun. Therefore, we should not throw our backpacks around carelessly, and we should regularly clean them to keep them tidy.

In summary, the backpack is an essential tool for both studying and our daily lives. If used correctly, it can bring us many benefits and can be considered a constant companion for each of us, especially for students - the future owners of the country.

8. Exposition on the School Item: Ballpoint Pen

Alongside the ruler, textbooks, notebooks, eraser,... the ballpoint pen is one of the necessary and very important study tools for not only students but all of us.

The ballpoint pen has a long history of formation. Before the invention of the ballpoint pen, people already knew how to engrave images, symbols, and languages of ethnic groups on bamboo cards, stones, shells,... The Chinese invented a feather pen written with Chinese ink a few centuries later. Until the recent century, Americans invented the fountain pen, then they invented the thick ink type. The ballpoint pen was born thanks to the talented hands of La Lô Bi-rô, an Argentine, who invented it. Then, Chinese merchants entered Vietnam after World War II, the structure of the ballpoint pen was only about a glove, consisting of two parts: the shell and the pen core, the shell made of hard plastic in many colors, diverse designs, with logos, manufacturer names printed on the pen body. The combination of design and color has made the pen more luxurious than ever. The pen core consists of a small tube containing ink, the metal head with a small ball attached. When we write, the ink will come out with the ball to create words. Ballpoint pens come in many types and varieties such as: retractable pens with spring-loaded cores, the pen tip will retract when we press the button at the top of the pen. There are also capped pens that are very simple to use, but we need to be careful when using them because if we accidentally drop the pen on the ground, the tip is straight down, the ballpoint will break and cannot be used anymore because the ink will not come out evenly. In addition, we can also see many other types of pens: feather pens, highlighter pens, glitter pens,... Pens are manufactured through many stages: First, select plastic and through the process of chemical reactions we will have a hard plastic type that is safe for the health of users. Then next is through the stage of dyeing, mold selection, plastic pouring, testing the durability and aesthetics of colors. All must be coordinated to create a perfect ballpoint pen in terms of quality and design.
