Worked example

Define science and technology. Explain the relationship between science and technology with two examples. (6 marks)

Science is the systematic study of the natural world through observation and experimentation to understand how things work. Technology is the application of scientific knowledge to solve practical problems and make life easier. Science and technology are closely related as science provides the knowledge and principles that technology uses to create useful devices and solutions. Example 1: Scientific study of electricity led to technological inventions like electric bulbs and motors. Example 2: Scientific understanding of electromagnetic waves led to technology like radio, television and mobile phones.

Common mistakes

Students confuse pure science with applied science - remember pure is for knowledge, applied is for practical use
Writing incomplete definitions - always write the complete textbook definition word by word
Forgetting to mention Pakistani examples like Tarbela Dam, nuclear technology in long answers
Mixing up biotechnology with information technology definitions
Not explaining the benefits of science and technology in Pakistani context

Quick recap

Science is systematic study of nature through observation and experimentation. Technology applies scientific knowledge to solve practical problems. They are closely related as science provides the foundation for technological developments. Key examples include electricity leading to electrical devices, and electromagnetic theory leading to communication technology.
