(The materials listed are for the experiment itself. I reserve the right to add

other materials as needed as I go along, which will be noted.)

Control/ Variable:

-The controlled experiment shall be 1 or several plants grown without

fertilizer/ stimulation.

– The variable in this experiment shall be the many plants grown with

fertilizer/ stimulation.

Sources Used So Far:

– A+ Book of Biology for Science Fairs

– Microsoft Encarta “CD” Encyclopedia

– Microsoft Bookshelf “CD” Encyclopedia

– World Book 1994 Edition

– World Wide Web (Internet)——–(magazine articles, notations, etc.)

Design:

The design of my setup will be basically many plants. What I will be

doing is waiting for half of the plants I grow to be about 1 inch high. Then to

half of those I will add a stimulant and let that whole half batch sit. Then I

will take the other beans, plant them then add the stimulant right away. Then

I will let that half batch sit. I will do this a few times with different stimulants

to see which one works the best and at which rate. The bean plants will not

be planted in soil for the fact that soil might provide excess stimulants which

will make the percentage of error greater than it needs to be.

Steps in experiment

So far:

- take 4 beans and plant them each in a piece of the construction paper

- take 2-3 more beans and plant them each in a piece of the construction

paper

- immediately take the set with 2 or 3 bean plants and add stimulant(s)

- wait until the set with 4 beans grows to be about 1 inch
