Water Quality & Conservation
📋 What it is
Testing water for clarity, life and chemistry reveals a waterway’s health — and how to protect it.
🗣️ Coach says
Healthy water supports life; polluted water doesn’t. Citizen scientists test streams and lakes for clarity, temperature, acidity, and the tiny creatures living there (sensitive bugs mean clean water). This data spots pollution early and guides conservation — protecting the water people and wildlife depend on.
🧠 Memory hook
Test water (clarity, chemistry, tiny creatures) → reveals health. Sensitive bugs = clean water. Guides conservation.

Why did the observation fail the quality check?
It didn't have enough supporting evidence — it was all anecdata!
😲 Whoa!
Scientists judge a stream’s health partly by its BUGS — certain mayfly and stonefly larvae only survive in clean water, so finding them is a sign of a healthy stream.
✅ Quick check: How can the tiny creatures in a stream reveal its water quality?
Say your answer out loud first — then reveal.
Some (like mayfly/stonefly larvae) only survive in clean water, so finding them signals a healthy stream.
Pollution-sensitive species indicate water quality.

Look closely at a clean stream’s pebbles for tiny bugs — their presence hints at healthy water.
