1.1Development in Chemistry Field and Its Importance in Daily Life

Chemistry is an essential branch of science that touches almost every aspect of our daily lives, from the food we eat to the medicines that keep us healthy. The term originated from the Arabic word 'al-kimiya'. Rather than being confined to laboratory experiments, chemistry helps us understand the matter surrounding us, how it is structured, its properties, its compositions, and how different substances interact.

Learning Objectives

  • 1.1.1 State the meaning of chemistry.
  • 1.1.2 State examples of chemicals commonly used in daily life.
  • 1.1.3 Generate ideas on the development of chemistry field and the contributions of chemical technology towards mankind.
  • 1.1.4 State examples of careers related to chemistry field.

Chemicals in Daily Life and Careers Related to Chemistry

Categorise common chemicals across major sectors and identify corresponding careers across modern chemical fields.

Food

Preservative, colouring, flavouring, antioxidant, stabiliser.

Medicine

Antibiotic, antiseptic, vitamin, chemotherapy, analgesic.

Agriculture

Herbicide, pesticide, fungicide, fertiliser, hormone.

Industry

Paint, polymer, glass, ceramic, detergent, colouring, alloy.

Brief Explanation

Understand the meaning of chemistry and how it appears in daily life.

Chemistry is a field of science that studies the structures, properties, compositions, and interactions between matters. The word chemistry originated from the Arabic word 'al-kimiya'. Chemistry is not limited to laboratory chemicals; it includes substances commonly found in daily life, such as salt and soap.

Meaning of Chemistry

Chemistry studies the structures, properties, compositions, and interactions between matters. All substances around us are made up of chemicals, and daily activities involve chemical reactions, such as the attractive colours of fireworks caused by a mixture of chemicals.

Development of Chemical Technology

Researches in various chemical fields constantly cover diverse disciplines, including biochemistry, botany, and forensics, which require chemical knowledge to solve problems. The need to solve modern problems spurs the development of chemical technology, as technologies from the 60s and 70s might not be suitable today.

Common Mistakes

Avoid these errors when learning about chemistry in daily life.

!
Assuming chemistry only refers to artificial, dangerous, or laboratory chemicals, whereas everyday substances like table salt, sugar, and soap are also chemicals.
!
Confusing career fields, such as placing a food scientist under cosmetics instead of nanotechnology or biotechnology.
!
Believing chemical preservation technologies have remained unchanged since traditional times, neglecting modern methods like freezing and nanotechnology.

Common Misconceptions

Compare each misconception with the correct fact.

Misconception

Chemicals are unnatural, synthetic, and harmful substances.

Correct Fact

All matter around us is made up of chemicals, including natural substances vital for life like water, salt, vitamins, and minerals.

Misconception

Careers in chemistry are restricted to laboratory technicians and academic chemists.

Correct Fact

Knowledge of chemistry is applied widely across varied modern professions, including doctors, green technology engineers, cosmetic consultants, and food scientists.

Summary

Key facts to remember.

  • Chemistry is the study of matter's composition, structure, properties, and interactions, originating from the Arabic word 'al-kimiya'.
  • Chemistry is ubiquitous in daily life, categorised across food, medicine, agriculture, and industry.
  • Continuous research and chemical technology have advanced problem-solving techniques, such as modern food preservation using nanotechnology.
  • Rapid industrial development creates vital careers in fields like biotechnology, pharmaceuticals, cosmetics, green technology, and nanotechnology.
