Possible Topics and Experimental Questions

Tonight I started brainstorming some topics I might like to research. I also started thinking about what I would experiment. I already know I want to have flowers in my project. So tonight I researched some flowers that grow quickly since we have three weeks for the experiment. The majority of the flowers I looked for took months to grow. I had to really search for flowers that would grow within the given time frame. I also want to use acid because it does destroy our environment and I think it will be useful to the GEA.

Possible Topics:
The affect acid rain has on impatiens
The affect of acid rain on Convolvulus
The affect acid rain has on zinnias
The affect acid rain has on cosmos
