Grow food with living water

How it works

Sample → Measure → Submit → Compare

1. 1

   Sample

   Same tank spot each week — mid-depth, after fish settle.

2. 2

   Measure

   pH and temperature with a rinsed probe or honest strip reading.

3. 3

   Submit

   Place nickname and region only — note feeding and what you observed.

4. 4

   Compare

   Patterns over weeks beat one lucky number — compare like with like.

Growing with science

Aquaponics links fish, plants, and water chemistry. These ideas help you read your numbers and grow better food.

• Nitrogen cycle

  Fish waste → ammonia → nitrite → nitrate → plant uptake. Stuck at ammonia? Note it.

• pH for tanks

  Many school systems target roughly 6.8–7.2 — compare your trend, not someone else's stream.

• Food production

  Healthy water grows healthy greens — log when you harvest and what changed that week.

• School inquiry world — living waterFull VOICE programme: nitrogen cycle, aquaponics builds, teacher packs.
• Freshwater ecology school unitFull VOICE programme for awa and aquaponics — not the same as tank logging alone.
• Aquaponics water quality studyFlagship guided study for classroom investigations.

Good to know

• pH for tanks

  Many school aquaponics systems sit around 6.8–7.2 — track your trend, not someone else's awa.

• Nitrogen cycle

  Fish waste → ammonia → nitrite → nitrate → plants. Stuck at ammonia? Note it and ask why.

• Growing food

  Healthy water grows healthy greens — log harvest weeks to connect chemistry and production.

How this pairs with school inquiry

Open here: Aquaponics tank pH and temperature with a place nickname. At school instead: Full awa monitoring, MCI stream visits, nitrogen cycle, and portfolio evidence

The primary paired unit is the paired school inquiry world— VOICE tools, portfolio, and teacher guidance. No class code is needed for open uploads on this platform.
