Raising Seeds

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

Method:

• We worked in groups of 3-4 students
• Potting mix was put into the cups.
• The cups were planted with bean seeds
• Each cup had a different growing condition:

1. Cup 1-normal
2. Cup 2-red cellophane
3. Cup 3-overwatered
4. Cup 4-underwatered or green cellophane or blue cellophane

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

Findings:

Plant growing condition	Height after 10 days (mm)
Normal	76mm
Blue cellophane	24mm
Red cellophane	80mm
Overwater Clear	38mm 59mm

The normal seedling was planted in a normal potting mix and grew to a height of ___76______mm.

The green cellophane seedling was planted in a 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 to a height of _______80____mm. The overwatered seddling was planted in a normal potting mix, the water could not drain out the bottom of the pot and it grew to a height of __38____mm.

Conclusion:

From the pictures and evidence we can conclude that:

The seedling height was:

1.76mm

2.80mm

3.38mm

4.24mm

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.
