ICSE Class 6 Chemistry — Flashcards

A: Chemistry is the branch of science that studies the composition, structure, properties, and changes of matter. For example, rusting of iron or cooking food involves chemical changes.

A: The three main branches of science are Physics, Chemistry, and Biology.

A: Alchemy was an ancient practice that aimed to transform base metals into gold and discover the 'philosopher’s stone' for immortality. It laid the foundation for modern chemistry through early experime

A: A chemistry laboratory is a special room where chemical experiments are performed, observations are made, and results are analyzed. It contains various apparatus and safety equipment to conduct experi

A: Observation helps us notice changes during experiments, like color change or gas formation. These clues help us understand what is happening and draw scientific conclusions.

A: An experiment is a controlled activity to observe a natural or created phenomenon. For example, testing how seeds behave in water to separate good and bad seeds.

A: Anything that has mass and occupies space is called matter. For example, book, water, air, and even the food we eat are all made of matter.

A: Living matter: Plants, animals. Non-living matter: Chair, water. Living things can grow and reproduce; non-living things cannot.

A: Air is matter because it has mass and occupies space. We can feel wind (moving air), and if you inflate a balloon, it expands — proving air takes up space.
