SS1 Chemistry First Term: Introduction to Chemistry
This opening topic introduces chemistry as a science, explains the laboratory, safe practices, apparatus, and the value of chemistry in everyday life. The page also includes a 40-question CBT quiz with a 15-minute timer and one-question-at-a-time navigation.
Introduction to Chemistry
Chemistry is the branch of science that studies matter, its composition, properties, changes, and the energy involved in those changes. It helps us understand the substances around us and how they interact.
What students should learn
- Meaning of chemistry and its branches.
- Importance of chemistry to the individual and society.
- Laboratory rules, safety symbols, and good conduct.
- Identification and use of basic laboratory apparatus.
- How science and chemistry support daily life and industry.
Branches and importance of chemistry
Branches
Organic chemistry, inorganic chemistry, physical chemistry, analytical chemistry, industrial chemistry, biochemistry, and environmental chemistry.
Importance
Medicine, food processing, water purification, fertilizers, soap production, metals, materials, and environmental control.
Science connection
Chemistry works closely with physics, biology, mathematics, and technology to solve real problems.
Laboratory rules and safety
- Do not eat, drink, or play in the laboratory.
- Wear proper protective clothing where needed.
- Read labels carefully before handling chemicals.
- Report spills, breakages, or accidents immediately.
- Use apparatus correctly and return them after use.
- Do not taste or directly smell unknown chemicals.
