SECTION 1
What's Happening?
And have you noticed that little trees sometimes grow far away from the big parent tree? The seeds are heavy. They can't fly! How did they get there? 🤔
- Why do you think bees visit flowers?
- How do you think seeds travel to new places?
SECTION 2
Big Ideas: Animals Help Plants!
Plants need help. They cannot walk or run. They stay in one place. But plants need to spread their seeds to new places. And many plants need pollen to move from one flower to another to make new seeds. That's where animals come in!
🐝 Pollination
🐿️ Seed Spreading
SECTION 3
Let's Try It!
🌸 Pollen on the Move
You will need: cheese puffs (or cotton balls with glitter), two paper plates (these are your "flowers")
Worked example
- 1
Step 1
Put a pile of cheese puffs (or glittery cotton balls) on one paper plate. This is the "pollen" in Flower 1. - 2
Step 2
Use your fingers to pick up a cheese puff from Flower 1. Look at your fingers — they are covered in orange dust (pollen)! - 3
Step 3
Now touch the second paper plate — Flower 2. What do you see? - 4
Step 4
Look at both plates and your fingers. Where did the "pollen" go?
What happened? The orange dust from the cheese puffs stuck to your fingers, just like real pollen sticks to a bee. When you touched Flower 2, some dust rubbed off. That's how bees move pollen!
How Do Seeds Travel?
SECTION 4
What We Discovered
When we did our "pollen" activity, we saw something important. The orange dust moved from one plate to the other — just by touching! This is exactly what happens when a bee visits real flowers.
Here is how it works. A flower makes sweet nectar (a sugary juice). Bees love nectar! When a bee crawls into a flower to drink the nectar, sticky pollen gets on its fuzzy body. Then the bee flies to another flower. Some pollen falls off onto the new flower. Now that flower can make seeds!
Seed spreading works the same way. Animals do not try to help plants. They are just looking for food! But when a bird eats a berry and flies away, the seeds inside the berry travel with the bird. When the bird drops the seeds, a new plant can grow far away from the parent plant.
| Animal Helper | How It Helps |
|---|---|
| 🐝 Bee | Carries pollen from flower to flower |
| 🦋 Butterfly | Drinks nectar and spreads pollen |
| 🐦 Bird | Eats fruit and drops seeds far away |
| 🐿️ Squirrel | Buries seeds and forgets some |
| 🐕 Dog / Deer | Seeds stick to fur and fall off later |
SECTION 5
Do You See the Pattern?
In science, we look for cause and effect. That means: when one thing happens, it makes something else happen.
When a bee visits a flower → pollen moves → the plant makes seeds. See? One thing causes the next!
This pattern shows up everywhere in nature! Let's look at more examples:
| Cause (What Happens) | Effect (What It Makes Happen) |
|---|---|
| A bee visits a flower | Pollen moves, and the plant makes seeds |
| A squirrel buries an acorn | A new oak tree can grow |
| Rain falls on soil | Plants can drink water and grow |
| The sun shines on a plant | The plant uses light to make food |

Real World Connections
People use what we know about animals and plants to solve real problems!
🍎 Farmers Need Bees!
Did you know that many of the foods you eat need bees? Apples, strawberries, blueberries, and watermelons all need bees to pollinate their flowers. Without bees, these plants would not make fruit! Some farmers bring beehives to their farms to help their plants grow.
🌻 Planting a Pollinator Garden
Here is something you can do to help! People plant pollinator gardens with flowers that bees and butterflies love. Sunflowers, lavender, and wildflowers all attract pollinators. If you plant these near a vegetable garden, more bees will come. More bees means more fruits and vegetables!
Think about it: Can you design a garden that would help pollinators? What flowers would you pick? Where would you put it?

Key Vocabulary
- Pollination — When pollen moves from one flower to another. This helps the plant make seeds.
- Pollen — A yellow, powdery dust found inside flowers. Plants need pollen to make seeds.
- Seed dispersal — When seeds are moved to new places, away from the parent plant.
- Nectar — A sweet, sugary juice inside flowers. Bees and butterflies drink it.
- Depend — When something needs another thing to live or work well. Plants and animals depend on each other.
