Hello ladies and gentleman. For the latest article, I briefly wrote about the information in chemical substances. Today, I would like to introduce my project on chemical substances. As I wanted to know the harmfulness of it, I had an experiment for the last few months.

 
     The experiment consists of two parts. The first experiment is to determine the impact on the amount of chemicals, whereas the second experiment is to see the effect on the different types of chemical substances. In this article I would like to discuss the first experiment, which dealt with the effects on the amount of chemical substances.

     Since I wanted to know the effects of chemical, I used kind of an indirect way. I did the experiment with bean plants. For each plant, I watered attenuated artificial flavor enhancer(in Korean, Miwon) and watched the growth. The experiment was done in two parts. First, I grew the plants for one week and saw the growth roughly, and in the second experiment, I grew them for one month and measured status precisely.

     So the following is the procedure of this experiment. First, I germinated bean on the Styrofoam dish. Then, in four pots, I planted four beans each. And then, I prepared three one litter bottle. In each bottle, I dissolved 20g, 40g, 60g of artificial flavor enhancer. After the beans grew about 5cm, I watered those artificial flavor enhancer water for one week. So, the manipulated variable is the amount of artificial flavor enhancer dissolved in the water.

Below are some pictures of preparing the experiment

These are the pictures and results of the experiment.

     The green pot was watered 'water', pink pot is 20g, blue pot is 40g, and purple pot is 60g. As you can see, the result was just like what I expected. The growth difference was so huge. But the interesting part was that the purple pot beans were even rotten! It smelled stinking and was covered with mold. (picture below)

  




     For the detailed experiment, I conducted the second experiment. The experiment was done in the same process for one month. But this time, I measured 4 things every week height, thickness of stem, the number of leaf, and the length of leaf. From the second week, I started to water 'artificialflavor enhancer water'. Look at the picture below.
