1. 10 gallon empty fish tank
2. Sheet of plastic (cut into dividers)
3. Soil (potting mix)
4. Wheatgrass seeds (5 packs)
5. Water (Poland Spring, Pure Alkaline, Fiji, Core, and tap water)
6. Measuring cup
7. Electronic Thermostat/Humidity reader
10. Paper, pen, tape, scissor, ruler (cm)
1. We gathered/bought all the supplies from stores or our homes
2. We first, cut the plastic into dividers creating 5 separate sections in the tank and taped them into place
3. We next, put 2 inches of soil evenly throughout the tank
4. We then, labeled each section of the tank and 5 bowls for each water brand
5. We filled each bowl with one pack of wheatgrass seeds and some of the specific water intended for each bowl
6. We covered the bowls in tinfoil and waited 10 hours before planting them into the soil
7. We matched each water type with the section and planted the seeds
8. We placed the tank by a window with even sunlight throughout the tank
9. Everyday we watered the seeds with 1/4 cup of the proper water for each section
10. Finally, we recorded the results
The wheatgrass was grown in a twelve day period and were watered every day with 1/4 cup. All the plants grew at a consistent rate. The average height of all the plants was 20.6 cm. Pure Alkline water was the smallest in height ending with a height of 19 cm.Fiji came out on top with an ending of height of 22 cm.
Over the span of twelve days the wheatgrass seeds were grown successfully. The plants were measured in the last five days of the growing period. The plants received equal sunlight and 1/4 of water everyday. The humidity ranged from 33% - 51% and the temperature ranged from 69-71° F.
Our data tells the observer a couple of important facts. One, that the higher the pH doesn't mean better growth of the plant. We saw this with the Pure Alkaline water, which is labeled to have a pH of 9.5 (higher than any of the bottles we tested). The Alkaline water ended with the smallest average height of 19 cm.
Next, fact we can state that the added minerals found in Fiji aided the growth of the wheatgrass. Fiji shown that it is the best water to use for growing wheatgrass over the other waters we tested. Overall our data concludes that the right combination of pH level and mineral content is the key to optimal growth of wheatgrass.
Our experiment was testing what water would grow wheatgrass the tallest. We used Core water, Poland spring water, Pure Alkaline water, tap water, and Fiji water. Our hypothesis was the plant watered by Fiji would grow the tallest, and we were correct. We believed that Fiji would be the best water for plant growth because it contains many minerals such as silica, calcium, magnesium, and biocarbonates.
The wheatgrass seeds were grown over a twelve day period. The plants received equal amounts of water, sunlight, humidity, and temperature. The wheatgrass was measured in the last five days of the twelve day span. All of the plants grew quickly but some grew more than others.
Wheatgrass can be grown with any type of water but for optimal growth Fiji water should be used. Wheatgrass needs many different minerals along with sunlight to grow to a large size. We could study the minerals in the water to see the effect they have on different plants. Overall our experiment, even though on a small scale, teaches us the importance of minerals and pH levels found inside water.
