Classroom Note:
What Is Water?
Water is a clear, colorless, odorless, and tasteless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.
Qualities Of Good Water
- It should be clear and colorless.
- It must be free from harmful chemicals.
- It should have no unpleasant odor or taste.
- It must be free from pathogenic (disease-causing) organisms.
- It should contain essential minerals for health.
Differences Between Water and Other Liquids
- Taste and Smell: Water is tasteless and odorless, while many other liquids like juice or soda have distinct tastes and smells.
- Boiling and Freezing Points: Water has a specific boiling point (100°C) and freezing point (0°C), which can be different from other liquids.
- Chemical Composition: Water is a simple molecule consisting of two hydrogen atoms and one oxygen atom. Other liquids may have more complex chemical structures.
- Solubility: Water is often called the “universal solvent” because many substances dissolve in it. Other liquids may not dissolve substances as well as water does.
- Density: Water has a unique density, which changes less with temperature fluctuations compared to other liquids. For example, water expands when it freezes, unlike most liquids which contract.
Importance Of Water:
- Hydration and Health: Water is crucial for staying hydrated. It helps in maintaining body temperature, and is vital for the functioning of organs and cells.
- Aid in Digestion: Water assists in the digestion process. It helps break down food so the body can absorb the nutrients.
- Transportation of Nutrients: Water acts as a carrier, transporting essential nutrients and oxygen to different parts of the body.
- Elimination of Waste: Water helps in the removal of waste products from the body through urination, perspiration, and bowel movements.
- Regulating Body Temperature: Water helps regulate the body’s temperature through sweating and respiration.
Evaluation Questions:
- What is water?
- Name three qualities of good water.
- How is water different from other liquids?
