(h) Observations

MdmDewi — 2024-02-28 01:04:02 UTC

1.The plants in pond water are greener but the plants in tap water are lighter green

(i) Conclusion

MdmDewi — 2024-02-28 01:04:02 UTC

1.The plants in pond water grew healthier than the plants in tap water.

(j) Follow-Up Research

MdmDewi — 2024-02-28 01:04:02 UTC

Pond water is suitable but you still need to use a balanced fertiliser or compost on your plants. Pond water does not provide all the nutrients they need.

Week 1: not checked

Week 2: Thin

Week 3: Thin

(i) Conclusion

MdmDewi — 2024-02-28 01:04:02 UTC

Changing the water once a day is better than changing the water twice a day.

(j) Follow-Up Research

MdmDewi — 2024-02-28 01:04:02 UTC

Changing the water once a day provides a steady routine for the seedling, which can help promote healthy growth and development.

However, it's essential to consider the specific needs of your seedlings and adjust your watering routine accordingly. In some cases, such as during hot weather or if the seedlings are particularly thirsty, watering twice a day with tap water might be more suitable.

Measure the height of the seedlings
Check the colour of the leaves
Count the amount of seeds not germinated
Check the thickness of the stems
The amount of roots each seedling has
Count the amount of leaves

(h) Observations

MdmDewi — 2024-02-28 01:04:02 UTC

The seeds in the pot with less amount of soil grew taller than the seeds in the pot with more soil.

(i) Conclusion

MdmDewi — 2024-02-28 01:04:02 UTC

As the amount of soil in each pot increases, the rate of germination of seeds decreases.

(j) Follow-Up Research

MdmDewi — 2024-02-28 01:04:02 UTC

Soil structure influences plant growth by affecting the movement of water, air and nutrients to plants. Sandy soils have little or no structure but are often free draining. With higher clay content, the soil structural strength increases, but its drainage ability often decreases.
