Plant Growth Experiment
What is the effect of coffee on plant growth compared to water? This is the question I was stuck to figure out. So, why would an average person care about the effects of coffee on plant growth? Well, the average growth time for a lima bean, when given water, ranges from 60 to 150 days. Information about plant growth is from various different websites. (http://www.harvesttotable.com/2009/03/how_to_grow_lima_beans/ , https://myfolia.com/plants/1917-lima-bean-phaseolus-lunatus , and http://www.ask.com/home-garden/long-lima-beans-sprout-cabd2a9cced32521). When I was finished in my experiment, the plant that was given coffee had grown in about 30 days. However, the lima bean plant that was given water has yet to sprout. So, why would the average

The questions include: How will the soil react to a more acidic substance such as coffee? Will the coffee absorb slower or faster than the plant that is given water? And lastly, Will the plants appearance be effected by the coffee? Luckily, I was able to answer each question through performing and observing the experiment. The first physical observation I was able to make happened after about 4 or 5 days of watering the plants with coffee. I had started to notice splotches of dark brown on the tannish pots. Over the next week the pots had completely changed colors. The second observation I made involved the soil. The soil in each pot were the same, but were starting to “act” differently. When I watered plant #1 (the plant that was being watered with water) the water was absorbed in less than five seconds. Although, when I watered plant #2 and #3 (the plants that were being watered with coffee) the coffee would sit on the top of the soil for about twenty or thirty seconds before it was totally absorbed into the soil. I was convinced this was happening because the coffee was denser then the water, but about twenty days into the experiment the coffee was starting to be absorbed much faster than the water. This leaded into plant #2 and #3’s soil to darken and stay more moist hours after being watered, and plant #1 to have dry soil that was starting to fade. I
