1. How do Seeds Travel?
November 28, 2011

2. Do now… Look at the three different types of seeds in your groups.
Make observations to figure out the different ways seeds might travel.
Record your observations and your ideas in your science journals and be ready to share.

3. Why do seeds need to travel?
Plants need to grow spread out so they do not block sun light or take nutrients from the soil.
Seeds are dispersed so that they can grow far away from each other.
Disperse: to scatter or spread apart

4. Seeds that are dispersed by wind
Some plants disperse their seeds through the wind. They are light enough to be carried.
Example: Dandelion
What makes a dandelion
seeds good for wind travel?

5. Seeds that travel by animal…
Fleshy fruit attract animals that eat the fruit, seeds and all.
Then the seeds are passed through in the animals droppings
They also get caught in animal’s fur

6. Seeds that travel by water
Coconuts are seeds that travel by water. Their outer layer allow them to float in the ocean to new places.

7. Lets make a seed that can travel by wind!
Using paper and scissors, design a seed that could be easily carried by the wind.
Think about seeds you know!

8. Reflect In your science journals,
Describe 3 different ways seeds travel.
Give an example of a seed for each (try to think of ones we have not talked about)
Why each seed is good for its form of travel
How this helps the plant survive in its environment.
