RESULTS
RESULTS
After I tested my experiment, the watercress grew more with Miracle- Gro potting mix than with Vigoro or KELLOGG potting mix. The watercress that grew with Miracle- Gro potting mix, grew 9 1/2 inches tall in total.
CONCLUSION
CONCLUSION
In my experiment, I tested which brand of potting mix helps watercress grow the fastest. My hypothesis was, If I grow watercress with Miracle- Gro potting mix, it will grow faster than using Vigoro or KELLOGG potting mix. The watercress that I planted in Miracle- Gro potting mix had grown 5 inches tall in all 3 trials. The watercress that I planted in Vigoro potting mix had grown 4 1⁄2 inches tall in all 3 trials. The watercress that I planted in KELLOGG potting mix had only grown 2 1⁄2 inches tall in all 3 trials. My hypothesis was correct, Miracle- Gro helped watercress grow faster.
ABSTRACT
ABSTRACT
The whole purpose of my experiment was to test different brands of potting mix. I have tested them to see which brand helps watercress grow faster. The different brands I used were Miracle- Gro, Vigoro, and KELLOGG potting mix. I chose this experiment because I like to eat watercress and it would be much better to know which brands make it grow faster. It would be better so I can grow watercress and won’t have to wait a long time for it to grow since I know which brand makes it grow faster.
In order to test this experiment I need to have procedures. First, Gather all materials, Watercress seeds, Miracle- Gro potting mix, Vigoro potting mix, KELLOGG potting mix, 3 planting pots, Water, and Sunlight. Secondly, Open up each potting mix bag. Third, Put one cup of one brand of potting mix into a pot. Then, Make the potting mix moist by adding one cup of water. Next, Put 10 watercress seeds on top of the moist potting mix. The following step would be to get 1⁄2 cup of the same brand of potting mix and place it over the seeds. Then, Make the small layer of potting mix moist by adding 1⁄2 cup of water. Next, Put the pot under the sun. After that, Keep on adding one cup of water when the potting mix gets dry again. Then, Observe and record data (Daily, every other day, etc ) and log in your table. Lastly, Repeat to complete for 3 total trials.
After I tested the experiment, I recorded my data. I found out that my hypothesis was correct. My hypothesis was “If I grow watercress with Miracle- Gro potting mix, it will grow faster than using Vigoro or KELLOGG potting mix.” I found out that Miracle- Gro helped watercress grow faster than using Vigoro, or KELLOGG potting mix. I know this is true because I measured the length of the watercress that was grown in each brand of potting mix. The
watercress that I planted in Miracle- Gro potting mix had grown 5 inches tall in all 3 trials. The watercress that I planted in Vigoro potting mix had grown 4 1⁄2 inches tall in all 3 trials. The watercress that I planted in KELLOGG potting mix had only grown 2 1⁄2 inches tall in all 3 trials.
The major finding of this experiment was to figure out which brand of potting mix is better to grow watercress. Miracle- Gro potting These findings could be used in day to day life because when I want to eat watercress I can grow them, and won’t have to wait a long time to eat them. This experiment could be improved if I tried it with many other different types of plants to make sure that Miracle- Gro potting mix is the best. It could also be improved if I tried it with different brands.
APPLICATION
APPLICATION
I could use the information from my experiment for every day to day life because I like to eat watercress salads and instead of waiting forever for them to grow, now I know what to use to plant watercress.
