Key terms
- potable water: In Potable water, potable water means water that is safe to drink and has low levels of dissolved salts and microbes. This matters in Using the Earth's resources and obtaining potable water because it supports the learning objective to explain why potable water should have low levels of dissolved salts and microbes. Use potable water only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.
- dissolved salts: In Potable water, dissolved salts means mineral salts that can affect the safety and quality of drinking water. This matters in Using the Earth's resources and obtaining potable water because it supports the learning objective to explain why potable water should have low levels of dissolved salts and microbes. Use dissolved salts only in this subtopic-relevant sense so the definition stays concise, curriculum-specific, and useful for AQA GCSE Biology revision. Students should use this term accurately when they explain the biology, identify symptoms, or justify an answer in GCSE Biology questions.
Common trap
Understanding Potable Water: Emphasize that potable water is safe to drink and may contain low levels of dissolved salts and microbes, while chemically pure water has no impurities at all.
