Experiment with Light Color - Knowledgebase Question

Question by zahra7

I'm doing this experiment with 4 different types of plants: Jade, Ivy, African Violet, and a Birdsnest Fern. I'm testing how different colors of light affect their rate of transpiration. I'm unsure of how to water them. Should I water them every other day with the same amount of water?

spectrum). Then average out the data from the 4 reps, and compare the four treatments. Also, when designing an experiment, you needto think of all the possible variables--like watering--and incorporate those into the design so that you are testing only one variable. You could even design an experiment that investigates if the amount of water a plant receives affects its rate of transpiration! I hope this is helpful, and good luck! spectrum).
