Claim # 2 was correct based on the experiment, due to the tobacco seeds which did not have any light changing their phenotype to white in all of the sprouts. It can be proven that light did have an effect due to the controlled variable sprouting more green tobacco plants than white.

# data[].attributes.body
no light petri dish:
-44 sprouts: all white
controlled peti dish (window):
-74 sprouts: 19 white, 55 green
florescent light rack:
-1 sprout: green
Ratio:
63:56 = 7:6

# data[].attributes.body
The seeds in the window have started sprouting, most visible sprouts are green.The seeds in the dark have grown roots, and the seeds under the fluorescent light rack haven't grown at all. We believe this is a result of not enough water so, we are slightly going to increase the amount of water.

# data[].attributes.body
Seeds didn't show any noticeable change, we added water to the seeds under the florescent light rack and the one in the draw.

# data[].attributes.body
no noticeable change, added water into the florescent light rank and the windowsill petri dish

# data[].attributes.body
1. always wear protective googles and aprons
2. keep seeds away from face
3. never do two things at once
4. report all accidents/spills
5. no food or drinks
6. no horseplay

# data[].attributes.body
3 petri dishes (used as the growth chamber)

Water bottle with distilled

200 tobacco seeds

Filter paper ( you can keep the tobacco seeds wet using filter paper and the bottom of the   petri dish)

Florescent light rack

box

# data[].attributes.body
Step 1: Put on safety equipment.
Step 2: Gather materials listed.
Step 3: Place filter paper on the bottom of each petri dish.
Step 4: Divide the 200 seeds among each petri dish.
Step 5: Add water into each petri dish.
Step 6: Place one petri dish underneath the florescent light rack, another on the window seal, and the last petri dish

# data[].attributes.body
Controls: # of seeds, amount of water, petri dish, type of filter paper
Independent Variable: light intensity
Dependent Variable: leaf color

# data[].attributes.body
Our group is trying to verify explanation 2:
Some environmental factors, such as the amount or the intensity of light, have no influence on the genotype of tobacco plants, but these factors can alter the phenotype of a tobacco plant as is grows.

Claim-which explanation does your group hope to verify?
Punnett square for the original cross.
Method..safety concerns, identify controls and independant and dependant variables, procedures.
