Write a report on plant growth
Answers
Explanation:
Purpose: Our group had a question on “How does increased UV light effect the
growth of a nasturtium seed?” and we did not have information to prove the hypothesis
was wrong or correct. So we decided to do this experiment.
Hypothesis: The UV lamp will affect the nasturtium seeds in a negative way because
too much exposure of UV light is not good. So we hypothesized that the nasturtium
seeds with the UV lamp will grow two inches less than the nasturtium seeds with
maximized sunlight.
Materials Used: Eighteen pots, soil, estimate of 104 nasturtium seeds, space next
to a window for eighteen pots, space for eighteen pots under a UV lamp
Procedure: 1. Have eighteen pots filled with soil and planted with six nasturtium
seeds for each pot.
2. Place one tub of nine pots near the window to maximize the amount of sunlight.
3. Place the other tub of nine pots away from any contact with the sun and under a UV
lamp light and don’t forget to turn on the UV light.
4. Water each and every pot with 10mL per pot using the beaker, every week day.
5. Record the growth of all the nasturtium seeds.
6. Average each growth of different tubs.
Conclusion: In the end, the UV light plants had grown taller than the sunlight plants.
There were no other differences between the two groups of plants except the height. Our
group’s hypothesis was not validated most likely because the sunlight did not get
sunlight on some days, according to the weather, or UV lights just happen to be a more
helpful in growth of plants. Our purpose was not fulfilled, I think to really find a solid
conclusion, a few more, same, experiments have to be carried out again.
Suggestions for further investigation: For further investigations, I
recommend that different variations of pots should be used because nasturtium plants
grow really long and tall, and they do not branch apart as much as other groups’ plants
had done. Also try using different UV lights and try to be in a stable weather
community.
What did you personally learn from the experiment? I personally had
learned many things. I learned on many steps of performing and conducting an
experiment, about nasturtium plants, how to take care of plants, lights’ effect on plants,
and more.
