In This Lesson
► Activity :
we will germinate some seeds in a wet paper towel, measure their growth and then compare their growth to the growth of the other seeds which are placed in soil.

► Steps :
1. Use the water to wet the paper towel.

2. Place three seeds in the top half of the paper towel and fold the bottom half of the towel up so that it covers the seeds then, place the paper towel inside the plastic plate.


3. Plant the other three seeds in the cup that contains potting soil then, water the seeds.

4. Place the plate and the cup in a place where they can get sunlight.

5. Check the growth of seeds over the next several days. Wet the paper towel and water the soil as needed.


6. Measure the growth of each seed using the metric ruler.


► Observations
- The initial growth of the seeds placed in the paper towel is similar to that of the seeds planted in the soil.


- The seeds grown without soil would not grow as quickly as the seeds in the soil.



► Conclusions
1. The seeds can grow without soil if they have water and Sun.
2. Plants can grow without soil for a while, but finally they need soil.


Notes

1. Plants can grow in a hydroponic system instead of soil.
2. Hydroponic system means a place full of water that contains the important minerals for the plant to grow.
