Adapting this mission to your community
- Replace the school rainwater tank with a real local water source (a bore, dam, creek, or community tank) if your community is comfortable sharing real numbers.
- Invite a local Water Ranger, Land and Sea Ranger, or council water officer to speak with the class about how they monitor water locally.
- Adjust the starting amount and daily rates to roughly match a real local water source's scale, even if exact figures aren't available.

The PDF is what you print. The Word file is what you edit, so you can swap in a local species, a local seasonal calendar, or local place names before the lesson.
