, Analysis of growth of basil when the amount of water is varied.
Aim:
To investigate and analyse growth of Basil seedlings when the amount of water is varied, to
determine the effect of water on the growth(height) of the Basil seedlings.
Hypothesis:
My Hypothesis is that the Basil seedlings with the most amount of water(100 mL)will survive
but the leaves will become yellow and the stem will droop due to too much water which is the
independent variable. Seedlings with the least amount of water(10mL Control)will die because of
lack of water, some signs such as brown and crisp leaves can tell that the plant is under watered.
The seedlings with the average amount of water(60mL)will thrive because of the perfect amount
of water and will grow the most. This is because the seedlings sensitivity to severe conditions
such as overwatering and underwatering can affect the growth negatively in the early stages of
the plant.
Variables:
Independent Variable: Water
Dependent Variable: Growth of the Basil seedlings(Height)
Controlled Variable:
● Amount of Sunlight
● Species of plant
● Size of Pot
● Height on first day of measurement
● Amount and type of potting mix
● Time of measurement
Materials & Equipment:
● 12x Basil Seedlings
