I. Introduction and Research:<\/p>\n
For Dr. Duncan\u2019s Science Methods EC-6 class, I have conducted an inquiry investigation<\/p>\n
over a plant\u2019s growth with a manipulated variable. The investigation will take four weeks to<\/p>\n
conduct. Throughout the four weeks, I will collect data weekly on the plant\u2019s growth progress. I<\/p>\n
am interested in studying about the plant\u2019s growth and testing my hypothesis. I will also have<\/p>\n
completed a research about plants during this investigation. By the final week, I will be able to see<\/p>\n
if a plant\u2019s growth is affected by the manipulated variable and if my hypothesis was correct.<\/p>\n
A. What Plants Need to Grow:<\/p>\n
For plants to grow, they must have light, water, and soil. With light, the plants are able to<\/p>\n
make their own nutrients. Some plants don\u2019t require as much light than others, but when a plant<\/p>\n
receives an incompetent amount, consequences will happen. \u201cWhen given a starvation diet of light,<\/p>\n
they will maintain their core life functions and give up the less necessary ones.\u201d (Huegel, C. N.<\/p>\n
(2019). Plants need water in their daily lives to preserve themselves. Most of the water that the<\/p>\n
plant receives is immediately lost as it\u2019s distributed where needed. The soil a plant grows in is a<\/p>\n
combination of \u201corganic and inorganic materials, water, air, and a huge variety of living<\/p>\n
organisms.\u201d Huegel, C. N. (2019). For the investigation, I will be using a constant soil, water, and<\/p>\n
the light will be the manipulative variable.<\/p>\n
B. Photosynthesis Explanation:<\/p>\n
Photosynthesis is needed in order for a plant to be able to survive, without it, the plant<\/p>\n
wouldn\u2019t be able to pertain energy. One of the biggest sources of energy that plants are able to<\/p>\n
receive energy from is the Sun. The plant uses the Sun when it \u201ctraps light energy from an outside <\/p>\n
Inquiry Investigation 3<\/p>\n
source.\u201d (King, J. (2011) Another important thing that occurs during the process is when \u201ctwo<\/p>\n
biochemical reactions that lead to the production of carbohydrates.\u201d (Jones, J. J. B. (2012)<\/p>\n
C. How Plants Get Their Water and Nutrients:<\/p>\n
For a plant to grow, they must also receive nutrients and water. \u201cThe essential plant nutrient<\/p>\n
elements are primarily taken up the roots as ions that exist in the soil solution.\u201d (Jones, J. J. B.<\/p>\n
(2012). There are many micronutrients and elements that are used for a plant’s nutrients. Another<\/p>\n
essential for a plant to grow is water. The plant intakes water in a few different ways. Majority of<\/p>\n
the time, the plant receives water that has been absorbed into the soil. Rainfall is another that that<\/p>\n
plants can receive water. In addition, the plant may also receive water through diffusion in the soil.<\/p>\n
D. Why Water is Important to Plant Growth:<\/p>\n
Just like all living things, plants need water to be able to function and survive. Even though<\/p>\n
majority of the plants water intake will most likely be evaporated sooner or later. Water keeps<\/p>\n
plants strong and able to grow. When water enters the plant, there are “chemical reactions in their<\/p>\n
cells, to keep living cells firm for functioning, and to prevent wilting of tissues and organs.\u201d (King,<\/p>\n
J. (2011)<\/p>\n
E. Ways Plants Adapt to Their Environments:<\/p>\n
No matter the environment of the plant, the plant will normally find ways to successfully<\/p>\n
receive water around them. If the plant is unable to receive water from precipitation, they can use<\/p>\n
their roots to obtain water that way. \u201cIn tropical rain forests, for example, where the humidity is<\/p>\n
high, aerial roots growing out from branches absorb water directly from the air\u201d is another adaption<\/p>\n
a plant will make. (King, J. (2011)<\/p>\n
Inquiry Investigation 4<\/p>\n
II. Rational for your Study & Research Question:<\/p>\n
During my investigation, I will be spending four weeks observing three different cups that<\/p>\n
I have planted seeds in. My manipulated variable will be different amounts of light used. My<\/p>\n
research question is, Does the amount of light given affect the plant\u2019s growth? I predict that<\/p>\n
increasing the amount of light will be the best environment for the plant. I also predict that<\/p>\n
decreasing the light will result in the plant diminishing. Therefore, my hypothesis will be,<\/p>\n
Increasing the amount of light provided will increase the growth of the plant.<\/p>\n
III. Materials and Data Collection Plan:<\/p>\n
I will be using materials to conduct my investigation. Everything will be constant except<\/p>\n
the light provided. There will be three cups filled with the same amount of soil. In each cup I will<\/p>\n
plant five radish seeds into each cup. I will spread out the five seeds evenly underneath the soil of<\/p>\n
the walls of the cup. By placing the seeds on the wall of the cup, I will be able to observe the<\/p>\n
growth since I will be using clear cups. The temperature or the location of the cups will not be<\/p>\n
changed once the investigation begins. The first cup will be placed in my kitchen window where<\/p>\n
it will receive 100% light. The second cup will be placed in the back of a hallway closet, where it<\/p>\n
will receive 0% light. The third cup will be put in the kitchen in a shaded area where it receives<\/p>\n
limited light 50% light during the day. The last material that I will provide to the plants is water.<\/p>\n
To test my data, I will be observing my plant\u2019s growth weekly. I began my investigation<\/p>\n
on October 17, 2020. Every Saturday, for four weeks, I took pictures of the growth of my plants.<\/p>\n
I kept an album of the pictures and labeled each picture I took. For the labels, I would write<\/p>\n
down what week the plant was on, and the amount of light the cup was receiving. I also was able <\/p>\n
Inquiry Investigation 5<\/p>\n
take notes of the process in my Science Journal. I would also draw pictures of what I was seeing<\/p>\n
with my plant growth, and any other notes I noticed with the growth at the time.<\/p>\n
IV: Results:<\/p>\n
After completing the investigation on November 20, 2020, I was very shocked to watch<\/p>\n
the entire process of the plant growth. It was very interesting to see how the manipulated variable<\/p>\n
affected the plant growth for all three cups. I figured since plants needs light, that the cup in 100%<\/p>\n
light would be the best environment. However, the cup in the 0% light grew taller than the cup in<\/p>\n
100% light. The main difference in the two cups were the appearance of the two. The cup in 100%<\/p>\n
light was not growing very fast, but the leaves and stem were green. The cup receiving 0% light<\/p>\n
grew tall quickly, but with the leaves a light brown. The cup receiving 50% light seemed to grow<\/p>\n
just as fast, and the leaves were also green, but the stems in this cup were all leaning towards where<\/p>\n
the light was coming from. I thought that was interesting to see that plants leaning trying to receive<\/p>\n
more light. I also noticed a difference in the leaves for all three cups. The leaves in the 100% light<\/p>\n
remained green the entire time, the leaves in the cup receiving 50% light started out green and<\/p>\n
eventually changed to yellow, and the leaves in the cup with 0% light remained yellow the entire<\/p>\n
investigation. During Week 3 of my investigation, the cup in the window with 100% light was<\/p>\n
accidentally knocked over which leaded to the investigation being complete a few days early.<\/p>\n
Below, you will see pictures I captured of all three cups during my investigation with a<\/p>\n
manipulated variable.<\/p>\n
V. Analysis and Conclusions:<\/p>\n
In conclusion, I have observed that although light is necessary for a plant\u2019s growth, the<\/p>\n
amount of light provided to the plant doesn\u2019t prevent a plant from growing. My hypothesis was,<\/p>\n
increasing the amount of light provided will increase the growth of the plant. Therefore, my<\/p>\n
hypothesis was wrong, because even the cup with 0% light was able to grow the tallest, just not<\/p>\n
the greenest. So, if the light impacted anything with the plant, it was how it looks and grows. The<\/p>\n
plant can grow in any light circumstances. All the cups were able to grow immediately once<\/p>\n
watered, the three cups just had a few differences by the end. The cup with 0% light grew tall<\/p>\n
quickly, however leaves were never green. They started with a dark yellow and faded even more<\/p>\n
throughout the weeks. The cup with 50% light was able to grow tall quickly as well with the leaves<\/p>\n
green during the first two weeks. By week three, the plant was leaning more towards the light<\/p>\n
source and started to look weak and began to wilt over the side of the cup. The cup with 0% light<\/p>\n
grew tall during week one and each week I was able to see the plant wilt more and more slowly<\/p>\n
down the cup. The leaves on the plant never turned green, they remained yellow the entire time. <\/p>\n
Inquiry Investigation 9<\/p>\n
Reflecting on the investigation, one thing I would do differently next time is to water more.<\/p>\n
I only watered the cups once a week, and when I felt like they needed more, I didn\u2019t want to change<\/p>\n
how I was watering, because this would interfere with another manipulative variable. For a future<\/p>\n
investigation, I would like to use different amounts of water as the manipulative variable to see<\/p>\n
how the plant\u2019s growth would be affected. I was surprised at how much I learned about the needs<\/p>\n
for plant growth and I have faith that the next time I try to plant something, I will be able to be<\/p>\n
more successful.<\/p>\n
In my future classroom, I think this would be a great project for 3rd grade students to<\/p>\n
complete. It makes a great hands-on experience for the students to be able to visually learn with. I<\/p>\n
would have the students create a hypothesis and make predictions and let them choose one<\/p>\n
manipulated variable for the student\u2019s to test plant growth with. The 3rd grade Science TEK that<\/p>\n
could be incorporated into the project is 3.3 A. \u201cScientific investigation and reasoning. The student<\/p>\n
knows that information, critical thinking, scientific problem solving, and the contributions of<\/p>\n
scientists are used in making decisions. The student is expected to: analyze, evaluate, and critique<\/p>\n
scientific explanations by using evidence, logical reasoning, and experimental and observational<\/p>\n
testing.\u201d (Texas Essential Knowledge and Skills for Grade 3. (n.d.) I chose this TEK because it<\/p>\n
allows the student to use critical thinking and be able to use evidence they have found to evaluate<\/p>\n
a hypothesis they create. They will also be observing their project with a certain amount of days<\/p>\n
or weeks to analyze information they research. By having students complete an investigation like<\/p>\n
this, it would benefit the visual and kinesthetic learners. <\/p>\n
