🌼🐝 Pollination STEM – Build a Working Pollination Model
A Hands-On Ecosystem Engineering Challenge (Grades 3–9)

Engage students in an exciting, hands-on STEM experience where they design and build a working model that demonstrates how pollination happens in nature! This interactive engineering challenge helps students understand how pollen moves from one flower to another and why pollination is essential for plant reproduction.

🌸 The Challenge

Students explore how pollination works and then create a model that demonstrates pollen transfer between flowers.

As shown in the challenge section (page 2), students are tasked with designing a working model that clearly demonstrates pollen movement.

They investigate:

• How pollen transfers from anther to stigma
  
• The role of pollinators like bees, butterflies, birds, bats, and wind (page 3)
  
• Why pollination is essential for plant reproduction and ecosystems
  
  

📚 What’s Included (14 Pages):

✔ Introduction & STEM Challenge
✔ Explanation of Pollination (with diagram)
✔ Parts of a Flower labeling activity (petal, anther, stigma, stem, ovary)
✔ Types of Pollination sorting activity (animal vs. wind)
✔ Materials checklist (construction paper, cotton balls, glitter/powder, pipe cleaners, cardboard base, spoon/brush tool)
✔ Design Requirements checklist
✔ Imagine page (two model designs)
✔ Plan Your Model blueprint page
✔ Build checklist & reflection
✔ Test Your Model data table (pollen transferred trials)
✔ Improve & redesign reflection
✔ STEM Connection page (Science, Technology, Engineering, Math links)
