What Will You Measure?

My group will be measuring the effect that a light rain versus a heavy rain has on a plant. Essentially to measure our plants progress, we will be looking at the height of the plants as well as the plants are growing. We will be looking at how fast the opposing plants will be growing, how big they grow, how healthy they look (full vs thin, etc.), etc. Regarding plant measurements, my group will be testing with a total of 12 pots. We are starting off with each pot having 3 seeds in it, so that there is a high chance that we will end up with 12 plants rather than anything lower.
