Technology

Technology is using ideas to solve real problems. Technology includes things you can touch, like tools and machines. It also includes things you cannot touch, like computer programs. Technology helps us in science, work, and every day.

Long ago, people made the first tools from stone. They used these tools to cut and hunt. Then people learned to make and use fire. Fire helped people cook food and stay warm. Scientists think cooking made human brains grow bigger. It also helped people learn to talk to each other. Later, someone invented the wheel. The wheel made it easier to travel far away. It helped people build better machines too. More recently, people invented the printing press. They invented the telephone and the Internet. These inventions made it easier for people to talk and share ideas.

Technology helps people make money and live better lives. But technology can also cause problems. Factories can make pollution and hurt nature. Some machines use up resources like trees and water. Sometimes new machines do jobs that people used to do. This can mean fewer jobs for people. Because of these problems, people argue about technology. They talk about whether technology is good or bad. They try to find ways to stop technology from hurting us.
