raising seeds

Aim: To look at the different growing conditions and how these affect the growth of seeds.


Method:


We worked in groups of 3-4 students
Potting mix was put into the cups.
The cups were planted with radish seeds.
Each cup had a different growing conditions:
Cup 1 - normal
Cup 2 - red cellophane
Cup 3 - over watered
Cup 4 - Under watered or green cellophane

The plants grew in their cups for 10 days before they were measured.

Findings:


Plant growing condition
Height after 10 days (mm)
Normal
35
Green cellophane
60
clear cellophane
30
Over water
0
The normal seedling was planted in normal potting mix and grew to a height of _35________mm.
The green cellophane seedling was planted in normal potting mix, covered in green cellophane and watered. It grew to a height of __60______mm. The clear cellophane seedling was planted in normal potting mix...and grew.......... to a height of ______30_____mm. The overwatered seddling was planted in normal potting mix, the water could not drain out the bottom of the pot and it grew to a height of ___0___mm.

Conclusion: green cellophane grew the best plant

From the pictures and evidence we can conclude that:

The seedling height was:

1. 60 mm
2.35 mm
3.30 mm
4.0 mm

The best growing conditions were:

1.green celophane
2. normal
3.clear celophane
4. overwatered

therefore the seedling with _____green cellophane________ conditions grew to a height of _____60____mm.
