What Effect Does the Depth of the
Seeds Have on the Height on the
Plants?

How Experiment was Conducted



The first thing that was done was wicks were put on the
bottom of each cell. Then fertilizer pellets and seeds were
put in and covered with more soil . The seeds were then put
on the watering system. In the experimental quad the seeds
were placed in the center of the cell, and on the others the
seeds were placed on the bottom of the cell.
The plants were observed every day in class . On day
thirteen, The plants heights were measured height in mm.
On day 21 the plants were pollinated with bees on sticks .
Finally on day 28 the plants were harvested. They were
harvested by taking off the pods and taking out the seeds
from each pod.
Control Variables
Amount of Seeds- We put three seeds in each cell.
 Amount of Fertilizer Pellets- We also put three
 Amount of Algae Squares- One in the watering
system
 Type of light- fluorescent 40 watts
 Amount of light- 24 hours for 40 days
 Type of soil- Unknown

Conclusions
 Wisconsin fast plants need to have water
24 hours a day
 They also need light 24 hours a day
 Seeds grow taller when planted in the
center of the cell not the bottom or the top
of the soil
Recommendations to Improve
Exterminations
 Make sure plants are on the watering
system at all times
 Make sure the lights are the same
 Make sure seeds are new
