Consideration

In this experiment, regarding sterilization, the copper plate was the best sterilizer among bleach, copper, carbonated water, pure rice vinegar, citric acid, soap, and baking soda. However, since the copper plate here is a copper plate that has been washed cleanly, it is advisable to wash the 10-yen coin cleanly when actually using it for sterilization. From this, we think that the red gerbera is the best in our two years of experimentation to put 5 grams of granulated sugar and a cleanly washed 10-yen coin in 100 ml of water. I will.

Conclusion

I experimented for two years. In the first year, I researched nutrition and found that granulated sugar was the best choice. Then, in the second year, I investigated sterilization, and as a result, copper had the most sterilizing effect and led to life extension. However, as you can see from the first experiment, it was found that clean copper that was washed is the most effective for sterilization.

Y.I: In this experiment, it was found that copper has the most bactericidal activity, and that the result does not change even if the size of copper is changed. In other words, if you use copper to extend the life of a flower, you can use it without worrying about the size of the copper.
K.A: I originally thought that copper had little bactericidal effect. However, looking at the actual results, I thought it was amazing that copper had the most bactericidal effect in the first, second, and third experiments and survived the most.
T.U: In this three-time experiment, we found that among natural water, citric acid, carbonated water, pure rice vinegar, copper, baking soda, bleach, and detergent, the copper plate leads to sterilization. However, this result came out when the copper was washed with baking soda, and the result may change with the 10-yen coin that you usually have. Please be careful. Furthermore, from the results of two experiments, it was found that the bactericidal effect of copper does not change depending on its size. From this, it is considered that even a 10-yen coin has a sufficient bactericidal effect.
H.I: In this experiment, the copper plate has the longest life. But to tell the truth, I didn't think about this result. I expected copper in the first experiment, but copper didn't give very good results in that experiment. In the second experiment, I thought that the baking soda used to clean the copper produced results. However, the last experiment proved that copper has the longest lifespan. I think this result is convenient. This is because it was found that everybody has copper as a 10-yen coin, and if you put in a few pieces, you can get a considerable bactericidal effect.
M.K: Copper was the most bactericidal in this experiment. It was true that copper had the longest life after conducting experiments for one month each, so even if I wasn't expecting it, I was satisfied with the result. I hope that the results of this experiment can be used as a reference when prolonging the life of flowers.
