Introduction

Science and technology are very important in modern society. Science helps us to understand the world around us, while technology helps us to apply scientific knowledge to solve problems.

Today, almost every aspect of life depends on science and technology.

Meaning of Science

Science is the systematic study of the natural world through observation and experimentation.

Meaning of Technology

Technology is the application of scientific knowledge to create tools, machines, and systems that solve human problems.

Relationship Between Science and Technology

Science provides knowledge, while technology uses that knowledge to create useful tools and innovations.

Example:

  • Science explains electricity
  • Technology uses electricity to power devices
