Educator’s guide and activities: Inspire your students to become water heroes

To help introduce this year’s National Water Week theme to children/students, we’ve created an Educator’s Guide. Designed to support learning in both early childhood and primary classrooms, this resource includes background information, discussion prompts, and activity ideas — all aligned with the 2026 theme, Water Heroes Make Every Drop Count.

Whether you're kicking off a water unit or supporting students in creating their posters, these resources will make it easy to bring the message of water conservation into your classroom in a fun, engaging and meaningful way.


Tips for uploading a poster

  • Poster size must be A4 or A3
  • Please ensure only high-resolution, high-quality images are submitted.
  • Image files should be in .JPG or .PNG formats.
  • Uploaded files are limited to 20MB.
  • Original posters can either be scanned or photographed.
  • Please contact us if you would prefer to send hard copies into our office: communications@coliban.com.au
  • If taking a photo, please ensure the image is clear and not blurred. Think about:
    • Good lighting.
    • Ensuring the poster fills the entire screen. An overhead shot is often best as you are standing above the poster, looking down.
  • Avoid using your flash as it makes a glary photo.

Judging

Winners will be chosen using the following criteria:

  • How well the poster communicates relevant water-related issues.
  • How well your poster reflects this year’s theme, 'Water Heroes Make Every Drop Count'
  • Whether the poster uses innovative imagery, design or concepts.
  • Whether art materials have been used effectively.
  • How attractive it looks from a distance.

  • When water lost her way
    By Meg Humphreys

    Lost in her ever-changing forms, 'Water' questions who she is after an encounter with a creature in an underground cave. Water seeks all parts of her cycle for answers, which makes her feel overwhelmed and confused. However, 'an old' tree helps her to understand her place in the world and her many interconnections with all living and non-living things.

  • You and Me Murrawee
    By Kerri Hashimi

    In this lyrical, beautifully observed story, a young girl camps by the river with her family. Through her eyes, we see life as it would have been two hundred years ago.
    Murrawee is friend and guide as we experience the rhythms of one day and become strikingly aware of what can be gained, simply by listening and sharing.
