Hypothesis

The hypothesis of this experiment was to see if the hydroponically grown

plants would be stimulated by electricity causing the seed to sprout

quicker than normally expected.

Materials

Gallon of Water
Schultz All Purpose Food Plus
Perlite
Two Plastic Four Inch Planting Pots
Four Green Bean Seeds
Grow Bulb
Two Plastic Treys
Two Large Tupperware Containers
Four Wood Blocks
Multi Meter

Procedure

Experiment

The solution was made by mixing one half teaspoon of Schultz

All Purpose Plant plus, a substance that contains Nitrogen,

Phosphate, Soluble Potash, Iron, Manganese, and Zinc, with a

gallon of water. Two planting pots labeled A and B were filled

with three inches of perlite. A plastic tray was placed under

both pots, and an inch of water was poured into it to create a

water table that the plant's roots would grow toward. A large

plastic Tupperware container was placed over both pots to

act as a green house. Wood blocks were placed under the

edged of the container so there would be some circulation of

air.

The plants were watered only when the table was under

an inch. Both plants were placed under a grow light for seven

hours every day. Plant A had two wires connected to a six-volt

battery. The wires were placed in the bottom of the tray for

about fifteen minutes a day. Plant B acted as a control.

Observations were made for nine days.

Results

The following results were noted for plant A:

On day four, the perlite was pulled back from the seed. The

seed had begun to grow a root system. On day nine, the tip of

the newly formed plant began to push through the perlite. On

day ten, the seedlings were removed from the perlite so that

the closer observation could be made. Ther was some

browning on the plant expecially around the edges of the

leaves. Plant A's growth was retarded. The larger of the two

plants in Pot A had a two-inch root system and a half-inch root

system and a one-inch system. Both of these plants were weak.

The following results were noted for Plants B:

On day four, the perlite was pulled back from the seed. The

seed had begun to grow a root system. On day eight, the tip of

the new plant was pushing through the perlite. On day ten, the

seedlings were removed from the perlite for observations. There

was little browning on the plants. Plant B's growth was healthy.

The larger of the two plants in Pot B had a three-inch root

system and a two-inch stem. The smallest had a two and a

half-inch root system and a one and three-fourths inch stem.

Both plants looked strong with thick stems and good root

systems.

Conclusion

The hypothesis was disproved. However, the experiment did

show that plants respond in a negative way to electrical

stimulation. The plants moved away from the...
