Transcript of Growing Plants With Different Liquids

Results:
Growing Plants With Different Liquids
Materials:
- Radish Seeds: Cherry Belle (21 seeds, 7 in each pot)
- 3 pots (terracotta was used)
- Ruler
- Labels
- Supply of 1% milk (44ml a day)
- Supply of orange juice (44ml a day)
- Supply of water (44ml a day)

Procedure:
1. Plant the radishes. Take the radish seeds and plant them as directed on the package. (seed depth- 1.3cm, seed spacing-1.3cm)
2. Label the pots. (milk, water, juice)
3. Every day, add 44ml of a certain liquid into its particular pot, till you see a significant difference.
4. Record data of height change over the days.

Concerns:
We had a few concerns about our experiment....
- Keep plants near a window so they can get a significant amount of sunshine
- Keep plants indoors so that no type of precipitation will be able to interfere with our test subjects


Background/Research:
- There are environmental factors that are affecting the plant growth, such as temperature, water supply and supply of mineral nutrients
- Too many minerals, or water supply will kill the plant
- Milk has a lot of nutrients, and so does orange juice (but not as many), which will affect the outcome

Question:
How does being watered with different liquids effect plant growth?
Hypothesis:
If we continuously water our plants with different liquids like milk, orange juice and water. The one being watered with water, will grow the tallest, as we know that most plants are watered with water, and if there were a more efficient way to grow plants, then it would be more known about.
Introduction/Purpose:
We are on a mission to find a healthy alternative to growing plants with water, that would possibly make the plants grow faster, stronger, and healthier, and so we decided to try using different liquids. For the past ten days, we have been growing cherry belle radishes using milk, orange juice and water to see if our hypothesis is true or not.

Discussions:
Plant: Milk – The plant managed to sprout the fastest, but was lacking in height, as it only reached 3.5cm, and the plant was drooping a lot, making it look especially unhealthy. We believe that there were
too many
minerals/nutrients in the milk which caused the plant to start dying.


day 10
Plant: Juice- Did not grow at all. There is mold covering the surface of the soil, not enabling plant life to break through the top, and sprout.
Day 1
Day 10
Plant: Water- This plant, as expected, grew the tallest and the healthiest. It sprouted after the milk, but continued to rapidly grow in height. At first we were a little nervous that this would be the only plant that would sprout.
Day 10
Day 8
Conclusion:
Our hypothesis was correct; the plant watered with water grew the strongest, healthiest, and tallest at 6.5cm. The juice did not help the plant at all, as it created a thick layer of mold on the top of the soil blocking the plant growth. The milk at first had surprised us as it had sprouted first, although, it later on started drooping and had an unhealthy looking appearance. From this experiment we have learned that out of these three liquids, water is the best choice for growing plants, but if we could further this experiment and find a different liquid, it could be used instead of water as a better way to grow plants.
Future Directions/ Improvements:
If we could continue our project we would try more liquids to see if we could get a different result, or maybe try using the environmental factors, such as amount of sunlight, or temperature.
