- 2.1. Use Friendly Presentation. Presentation is the heart of the teaching process.
- 2.2. Illustrate with analogies. Even the most abstract concepts in chemistry can be illustrated by examples or by analogies.
- 2.3. Correlate with everyday life. Chemistry touches all aspects of our lives.
Why Is chemistry important for kids?
Chemistry helps us understand how the world around us works. The importance of teaching chemistry to our children is clear. Our future scientists depend on it. And raising children with a solid foundation in reason, who aren’t easily fooled, and have a clear understanding of world they live in is reason enough.
What are the 3 main branches of chemistry?
- Organic Chemistry.
- Inorganic Chemistry.
- Physical Chemistry.
What are the 2 main branches of chemistry?
The primary division of the first type is between inorganic chemistry and organic chemistry. Divisions of the second type are physical chemistry and analytical chemistry.
What is the most important branch of chemistry?
Biochemistry. Known to be one of the most important branches of Chemistry, Biochemistry studies the biological structure, composition and chemical reactions at the cellular and molecular level.
What is the most important thing to learn in chemistry?
In order to understand how chemists explore the world, you’ll need to understand how to take measurements, use glassware, use chemicals safely, and record and analyze experimental data.
What order should I learn chemistry?
You can study these concepts in any order, but it’s probably best to start from the top and work your way down, since many concepts build on understanding units, conversion, and how atoms and molecules interact.
What is the importance of chemistry?
Chemistry is essential for meeting our basic needs of food, clothing, shelter, health, energy, and clean air, water, and soil. Chemical technologies enrich our quality of life in numerous ways by providing new solutions to problems in health, materials, and energy usage.
Who invented chemistry?
Antoine-Laurent de Lavoisier (1743–94) is considered the “Father of Modern Chemistry”.

- Discolouration of leaves.
- Food Digestion.
- Common salt.
- Ice floating on water.
- Tears while chopping onions.
What will happen without chemistry?
Without chemistry people would die much younger from diseases such as bubonic plague, since we wouldn’t have antibiotics. We wouldn’t have vaccines, so people would still contract terrible illnesses such as smallpox and polio. Even a simple skin infection might lead to death.
How does chemistry impact our daily lives?
The industrial applications of chemistry directly affect our daily lives—what we eat, what we wear, our transport, the technology we use, how we treat illnesses and how we get electricity—to name just a few. Research is constantly deepening our understanding of chemistry, and leading to new discoveries.
