【Social Studies - 5th Grade】 Information-Based Society: How is Our Life Changing?
Hello everyone! Starting today, we’re going to learn about "Information" together. In the world today, we can get a huge amount of information anytime and anywhere thanks to smartphones, television, and the internet. We call this a society with advanced "informatization." You might think, "Information sounds a bit complicated...", but don't worry! In reality, information is useful to you all around your daily life. Let’s have fun uncovering how these systems work in this note!
It might feel a little tricky at first, but try reading it as if you’re learning about the "magic mechanisms" that make our lives so convenient.
1. Various Ways of Communicating Information
We exchange a ton of information every day. Did you know there are two main ways it gets transmitted?
① Mass Media (Communicating to many people at once)
Things like television, newspapers, radio, and magazines that deliver the same content to many people at once are called "mass media." (Example: Morning news, newspapers reporting on Shohei Ohtani’s performance, etc.)
② The Internet (Finding what you want to know yourself)
Using a smartphone or computer, you can choose and view only the information you want. A huge feature of this is that anyone can share information, just like on social media. (Example: Watching videos on YouTube, searching for research projects, etc.)
★ Key Point
Mass media is great for telling us "things everyone should know," while the internet is perfect for digging deeper into "things you personally want to know." The trick is to use both in a balanced way!
2. Information at Work Behind the Scenes of Shopping (POS System)
When you shop at a convenience store or supermarket, you hear a "beep" as they scan the barcode at the register, right? That scan is packed with amazing information that keeps the store running smoothly. This is called a "POS (Point of Sale) system."
What the POS system tracks
Every time something is scanned at the register, information like this is sent to the store's computer:
・What was sold (rice balls, tea, etc.)
・When it was sold (lunchtime, late at night, etc.)
・What kind of person bought it (gender and general age group)
How is this information useful?
Store staff analyze this collected information to make smart choices, such as:
・"It's going to be hot tomorrow, so let's stock up on more ice cream!" (Adjusting inventory)
・"Elementary students often buy this snack in the evening, so let’s put it on a lower shelf!" (Store layout adjustments)
💡 Trivia: "Dead" Items
Thanks to the POS system, stores can quickly identify products that aren't selling well (these are sometimes called "dead items") and replace them with new, popular products. That’s why convenience store shelves are always so appealing!
3. Information in Healthcare and Disaster Prevention
Information is also indispensable for protecting our lives.
Use in Healthcare (Hospitals)
Large hospitals manage patient information digitally. Sometimes, doctors who are far away can provide medical advice over the internet. This is called "telemedicine."
Use in Disasters (Earthquakes and Heavy Rain)
When an earthquake happens, you receive an "Emergency Earthquake Early Warning" on your TV or smartphone, right? This is a system that takes advantage of the speed of information. By having the Japan Meteorological Agency and local governments share the current situation quickly, they give us time to evacuate safely.
★ Summary!
Information doesn't just make things "convenient"—it plays a vital role in supporting a "safe and secure" life.
4. Using Information Correctly (Information Morals)
An information-based society is convenient, but there are "pitfalls" we need to watch out for. Let's learn the rules for using it properly, known as information ethics (or information morals).
① Protect Personal Information
Names, addresses, school names, and photos of yourself are things that, once put on the internet, can never be completely deleted. This is called "personal information." Handle your own information and your friends' information with care.
② Verify the "Truth" of Information
Sometimes, "fake" information (misinformation/rumors) circulates on the internet. It is important not to believe everything you see, but to have the ability to ask, "Is this really true?" (this is called media literacy).
❌ Common Mistakes
Thinking, "It's okay to say mean things to my friends on social media because I'm anonymous (hiding my name)" is a mistake. It is always possible to figure out who wrote something. Don't forget that there is a "real person" on the other side of the screen.
⚠️ Point Box
・Never tell anyone your password!
・Do not reply to messages from people you don't know!
・If something happens, consult an adult immediately!
Finally: To You, Living in the Future Society
The information-based society will continue to evolve. AI (artificial intelligence) will become even more familiar, and new tools will keep appearing.
The important thing is not to be swayed by information, but to use information skillfully as your own "tool." It's okay to start a little at a time. For starters, try asking yourself, "Where did this information come from?"
Today's Summary:
1. We use both mass media and the internet to communicate information.
2. The POS system makes shopping in stores more convenient and efficient.
3. Information protects our lives through healthcare and disaster prevention.
4. It is important to follow the rules for using information correctly (information ethics)!
