Science studies the physical world, that is, properties and behaviour of different objects. Scientists do it by asking questions "what" and "why". For example, they ask: "What is lightning?", "Why does it happen?", "How does lightning work?" These questions help scientists to find explanation to natural facts and processes.

Technology is the use of science for practical purposes and it is also all those methods, machines and tools that are used in doing things in a science or profession. Engineers and inventors use scientific discoveries to design and build new things. Technology asks and answers "how" questions.
