  • Agriculture
  • Compost / Soil Health
  • Community Action

Note: You can work by yourself, your whānau, or in a group.

 

3. Choose ONE way to show your solution

📌 OPTION 1: Poster - Show the problem, your solution, how microbes work (MRS GREN), and the impact.

📚 OPTION 2: Comic Strip - Microbe characters solving a problem!

🧪 OPTION 3: Mini Model or Prototype - Build a tiny compost bin, wetland, soil hotel, or microbe-powered device.

🕵️‍♀️ OPTION 4: Detective Report - Write a 1 page mystery case about microbes solving the problem.

✍️ OPTION 5: Infographic / Fact Sheet - Show the problem, a helpful microbe, your solution, and 3 key facts.

🎨 OPTION 6: Story / Poem / Creative Writing - Tell a story from the viewpoint of a microbe, soil, compost pile, or community. 

Theme examples: Agriculture

Example 1: Microbe booster for soil.

  • Kids design a pretend “microbe booster” that helps plants grow strong.
  • Choose 3 helpful microbes (e.g. nitrogen helpers, disease fighters, decomposers)
  • Draw or build a container (bottle, sachet, seed coating)
  • Name their product and explain how it helps plants

 

Example 2: Poster comparing healthy vs unhealthy roots.

  • Create a comparison poster showing what roots look like with and without microbes.
  • Split a page into two sides
  • Draw roots with microbes (thick, fuzzy, lots of life)
  • Draw roots without microbes (thin, weak, cracked soil)

 

Example 3: Comic about microbes fighting plant diseases.

  • Make a short comic where microbes defend a plant from disease.
  • Invent a villain (fungus, bad bacteria, drought monster)
  • Create microbe heroes with powers  
  • Show how the plant is saved 

Theme examples: Compost / Soil health

Example 1: Mini compost system.

  • Design or build a mini compost system
  • Draw or build a compost jar/bucket
  • Label what microbes eat (food scraps, leaves)
  • Show what compost becomes (soil!) 

 

Example 2: Decomposition race poster.

  • Predict which items decompose fastest
  • Choose 5 items (apple core, paper, plastic, leaf, banana peel) 
  • Rank them from fastest to slowest 
  • Explain why

 

Example 3: Detective case: The Disappearing Apple Peel.

  • Solve a mystery using microbial clues
  • Write a case report
  • Draw microbes as detectives
  • Explain how microbes made it disappear

Theme examples: Community action

Example 1: Microbe Heroes education campaign.

  • Create a campaign to teach others about helpful microbes.
  • Design a poster, sticker, or mini video idea
  • Create a slogan (e.g. “Microbes Make Our World Work!”)
  • Choose where it would be shared (school, town, farm)

 

Example 2: Story about microbes cleaning pollution.

  • Write or illustrate a story where microbes clean up pollution.
  • Choose a problem (dirty river, oil spill, landfill)
  • Show microbes breaking it down
  • End with a healthier environment 

 

Example 3: Fact sheet: What Microbes Do for Our Town

  • Create a kid-friendly fact sheet.
  • List 5 ways microbes help (wastewater, soil, food, compost)
  • Add drawings or icons
  • Make it easy for others to understand 

Theme examples: Community

Community

  • 5-minute shower challenge
  • Tap-off reminder signs
  • Refill station 

 

Example 1: 5-minute shower challenge - This is a challenge to help people use less water when they shower.

  • Use a timer, a song, or a stopwatch
  • Try to finish your shower in 5 minutes or less. This saves water and energy.
  • You could make this a neighbourhood challenge!
  • Invite people on your street to join in
  • Keep track of how many people try the challenge
  • Celebrate together if everyone takes part
  • Bonus idea: 
    You could organise a street BBQ, shared afternoon tea, or picnic as a prize or celebration for everyone who joins the challenge.
  • This helps save water and brings people together. 

 

Example 2: Tap-off reminder signs - These are friendly reminders near taps.

  • Signs that say “Turn me off!”
  • Pictures that remind people to save water
  • They help people remember not to waste water. 

 

Example 3: Refill station at school - A refill station is where students can fill their drink bottles.

  • Instead of buying plastic bottles
  • Everyone brings their own bottle
  • This reduces plastic waste and helps the environment.
