Transcript of problem statement:

background: i learned hydroponics is growing plants in water. i thought this sounded interesting so i looked it up, and decided to try it for my lab project.

my hypothesis
my hypothesis was that plants will grow better in water, instead of soil.since i can control what elements go into the nutrients, what happens and what conditions and ideal nutrients solution for what makes a perfect, healthy plant.
problem statement:
do plants grow better in water or soil?

EXPERIMENT DESIGN
The constants in this study were:
-Same kinds of seeds
-Same kind of water
-Same amount of water
-Same kind of cups
-Same size of cups
The manipulated variable was growing the plant in water or soil
The responding variable was the plant’ total length.
To measure the responding variable I will measure the length in millimeters using a ruler.
soil results:
water results
plants height
-Same kinds of seeds
-Same kind of water
-Same amount of water
-Same kind of cups
-Same size of cups

conclusion:
my hypothesis was somewhat correct.my hypothesis was that plants will grow better in water, instead of soil.since i can control what elements go into the nutrients, what happens and what conditions and ideal nutrients solution for what makes a perfect, healthy plant.the results indicate that the vegetables didn't grow better in water so this part of the hypothesis should be rejected. The flowers grew better in soil so this hypothesis should be accepted. I thought the grass would grow equally well in both water and soil, but it grew much better in soil so my 3rd hypothesis should be rejected.
Because of the results of this experiment, I wonder if plants would grow equally well in soil and water with fertilizer.
If I were to conduct this project again I would grow a wider varity of plants to get a more accurate idea of which plants grow better in water or soil.
