To look at the different growing conditions and how these affect the growth of seeds.
Method:
1. We worked in groups of 3-4 students.
2. Potting mix was put into the cups.
3. The cups were planted with the beans.
4. Each cup had a different growing.
Cup 1- normal
Cup 2- red cellophane
Cup 3- overwatered
Cup 4- blue cellophane
Cup 5- clear cellophane
The plants grew in their cups for 10 days before they were measured.
Findings:
Plant growing condition
|
Height after 10 days (mm)
|
Normal
| 76 mm |
blue cellophane
| 24 mm |
Red cellophane
| 80 mm |
Overwater
Clear
| 38 mm 59 mm |
The normal seedling was planted in the normal potting mix and grew to a height of 76 mm.
The blue cellophane seedling was planted in the normal potting mix, covered in blue cellophane and watered. It grew to a height of 24 mm. The red cellophane seedling was planted in the normal potting mix and watered. It grew to a height of 80 mm. The overwatered seedling was planted in the normal potting mix, the water could not drain out the bottom of the pot and it grew to a height of 38 mm.
Conclusion:
The seed that was watered correctly and covered in red cellophane was the one that grew the most.
From the pictures and evidence, we can conclude that:
The seedling height was:
1. 76 mm
2. 80 mm
3. 38 mm
4. 24 mm
The best growing conditions were:
1. red
2. normal
3. clear
4. overwatered
therefore the seedling with the best conditions grew to a height of 80 mm.
