NOT TALKING!

2. Warm-Up
What does the word germination mean? Look at the picture, it will help!

3. Germination: start to grow from a seed or spore into a new individual plant
Conditions are right for seeds and spores to start to grow and develop into a plant

4. Video on Seeds:
Brain Pop
Listen for how seeds grow and the different types of plants that produce seeds and spores

5. AGENDA:
1. Stations around the room
2. Lima Bean Lab

6. Write the “Process of Seed Germination”
Station 1
Write the “Process of Seed Germination”

7. Process of Seed Germination
Seeds are protected by a hard shell or seed coat. This shell is VERY tough!
Sometimes seeds need to be eaten by animals to get ride of the hard seed coat.
This helps the seed coat soften and lets germination happen
For others, simply soaking the seed in warm water will soften the seed coat enough.

8. Draw this picture of the process of seed germination…
Station 2
Draw this picture of the process of seed germination…

10. Station 3
Write about what seeds need to grow and what “dormancy” means…

11. Let’s grow! Seeds need the RIGHT conditions to grow... Water Sunlight
Temperature

12. Dormancy means… Dormancy means inactivity.
For example, when you are sleeping, you are not being active.
Some seeds require a period of DORMANCY before they germinate (grow).

13. Station 4
Why are seeds dormant and how do they wake up?

14. Why are seeds dormant?
Seeds become dormant when conditions are not good.
Typically seeds that are dormant are VERY dry and it takes them longer to swell with the water.
Seeds can be dormant for YEARS!!!!

15. What conditions do they need to come out of dormancy?
moisture
temperature
light
Some seeds need complete darkness to germinate
and in some cases even fire

16. Station 5
Write information for Seed Germination and draw the picture

17. Seed Germination
Seed germination: the process whereby seeds or spores sprout and begin to grow
This is when the seed swells up with water and begins to grow.

18. FUN FACT
Did you know that pinecones can only release seeds from being dormant when they are LIT on FIRE!

19. Germination

20. Before dissecting your lima bean, answer these questions in your notebook using complete sentences:
1. What does the dry seed look like?
2. How big is the dry seed? Trace the seed in your notebook.
3. How is the wet seed different from a dry seed?

21. How to dissect your lima bean:
Pull off the seed coat

22. How to dissect your lima bean:
Split the lima bean in 2 (pull away from the indentation)

23. Answer these questions in your notebook. Use complete sentences!
What does the split seed look like on the inside?
Explain what you see inside.
Why do you think the bean is SO much bigger than the tiny structure you see inside?
