Plant Growth Ashton Abernethy

Potting soil
Water
Green Light
Red Light
Procedure:
1. Gather Materials
2. Pot the bean seedlings

See graph on other page
Analysis:
My analysis of the experiment was that the plant under red light grew the best. The one in the window grew the 2nd best, and the ones under the green light and in total darkness died.
Conclusion:
My hypothesis was incorrect. The plant under the red light grew better than the one under the normal sunlight.
1. No, the data did not support the researcher’s hypothesis because the researcher guessed that the window plant would grow better but it didn’t.
2. It was important to record each seedlings initial height because then you know for sure which one grew the most.
3. It is important for each seedling to get the same amount of water because then you would have 2 variables. A project should only have 1 variable.
4. The researcher could conclude that plants do not grow good in darkness or under green light.
5. Plant A, the one in the window, would be the control
