Exploring Germination
Growing Beans in a Bag
Slip several damp paper towels into a Ziploc bag. Insert 5 staples half way up the bag.
Slide in a few beans. The staples will keep them in the right place so that there's room for the roots to grow.
Three days after "planting" the first roots appear.
A few days later: The stems start to push upward.
After ten days the leaves begin to peek out of the seed coat.
Two weeks: the first true leaves appear while the stem continues to grow and grow!
How tall will they get? (Larry is sure they'll touch the ceiling!)
One student brought his bean shoot home, transplanted it in dirt, and proudly reported that his plant grew three bean pods!
Instructions:
- Place a damp, folded paper towel into a zip lock bag.
- nsert 5 staples about half way up the bag. This will keep the beans in the right place so that there's room to watch the roots grow.
- Place a few beans into the bag.
- Tape the bag onto a wall or window. Add water as needed to keep the paper towel damp.
