Planting Science Lab WriteupQuestion;! Will different liquids affect the germination of Mung Beans and Wheat seeds. Specifically after six days have passed will there be a difference in the size of the shoots in different groups of liquids. These liquids are Tap water, salt water, Smart water and a control dry group.

Independent Variable: Type of liquid used.Dependent Variable: Length of sprout after 6 daysControl Group: Dry

Hypothesis;! Our belief is that the group of seeds germinated in smart water will grow the fastest because the nutrients in smart water will help supply the plant with the necessary nutrients for the seedling grow faster.

Materials: -A role of paper towels-A liter of smart water -1960 ML of tap water-35 ML of table salt-4 zip-lock plastic bags-1000 ML beaker-tape and marker (labeling)-20 mung beens, 20 wheat seeds

Instructions: Do each of the following steps for each of the respective groups. These groups include smart water, salt water, tap water, salt water. Note for salt water use a concentration of 35 parts salt per thousand parts solution. Also for the dry group you do not need to moisten the paper towels

1. Moisten a 12” square of paper towel with the liquid chosen and lay it out on a flat surface. 2. Place five Mung bean and 5 wheat seeds on the paper towel3. Place a second paper towel moistened in the liquid used on top of the first paper

towel with the seeds sandwiched in-between. 4. Roll un the paper towel “sandwich” into a roll.5. Place this roll in a ziplock bag. Seal and label the bag for future reference.6. Each day check the status of the group. Record any observations. Our group took

pictures.

7. On the sixth day take out the seeds and measure the roots on the wheat seeds and the roots on the Mung bean(if any).

Day Observations

one Wheat seeds are approximately 3mm longMung Bean seeds are approximately 5mm longThe seeds roll around in the dry group while the seeds stay relatively still in the moist groups

two Tap: The radicle has emerged on the mung bean and appears to be 6 mm long the roots have emerged on the wheat seeds and appear to be 5 mm longSalt: the seed appear to be wrinkled on Mung bean and wheat seedsSmart: the radicle is curling out and appears to be 1.5 mm long on the Mung bean The radicle has emerged on the wheat seed and appears to be 1.5 mm longDry: no apparent change in seeds

three Tap: the Radicle is emerging and appears to be 7mm long on the Mung bean.Salt: the seed appear to be wrinkled on Mung bean and wheat seeds also the color is fading into the paper towels Smart: the radicle is curling out and appears to be 8 mm long on the Mung bean The roots have emerged on the wheat seed also the epicotyl has emerged on the wheat seedDry: no apparent change in seeds

four and five We were not at school due to the weekend, the grow light above the seeds was turned off due to safety concerns

six Tap: One mung bean is moldySalt: No germination activity, seeds are soft and seed coat is very weakenedSmart: One wheat seed did not germinate, seeds are growing into the paper towelsDry: no apparent change in seeds

Analysis of the data:! From my observations it appears the smart water grew faster at the start of the experiment however at the end of the growth time the tap water had clearly overtake the tap water in growth progress. The dry and salt water showed no signs of germination.

Conclusion:! Regular old tap water helped grow the mung beans and the wheat seeds the most. As we expected the seeds in the dry group did not germinate. Neither did the seeds in the salt water group. This can be expected because none of the seeds we used were for salt water plants. Upon further research on Smart water[1] I found out that it contains vapor distilled water and electrolytes. Vapor distilled water is water that has been cleaned at a lab to remove almost all impurities[2]. Reading another planting science report about electrolytes it appears that they(electrolytes) do not help the germination of plant seeds.[3]. Thus the hypothesis is wrong, it turns out that tap water is best for germinating plants.
