You Are To Write A 1 2 Page Paper Describing
A Scientific Investigatio
You are to write a 1-2 page paper describing a scientific investigation of your choice. This does not have to be actual research that you perform, although if you have an idea for a simple experiment or study that you could do you are encouraged to carry it out. For the sake of simplicity, we divide the scientific method into eight steps. In this assignment, you will write a short paragraph for each step. Read the examples below to see how you should approach this assignment.
1. Define a question: Identify and describe a question, problem, or phenomenon that you want to understand.
2. Gather information and resources: Research possible explanations of the question, drawing from observations and experience.
3. Form an explanatory hypothesis: The hypothesis needs to be an explanation of how the phenomenon works, and the hypothesis should make specific predictions that are testable.
4. Test the hypothesis: Describe the experiment or observations that would specifically test whether the predictions of the hypothesis are true.
5. Analyze the data from the test: Describe how closely the results of the experiment matched the predictions of the hypothesis.
6. Interpret the data and draw conclusions: Explain whether the test falsifies the hypothesis or whether it supports the hypothesis. If your hypothesis is supported by the test, list any alternative hypotheses that could possibly explain the results as well.
7. Publish results: Find a journal or trade publication to submit your findings to. If the journal or magazine finds your study to be accurate and interesting, it will publish your article to share your results with your peers.
8. Retest (often done by other scientists): Your peers may want to check your work or build on it. Describe how you would expect someone working in the field to react to your study. Would they find it surprising? Interesting? Do you think they would agree with your conclusions? Do you think they might have an alternate hypothesis to explain the phenomenon?
Title: Investigating the Effect of Light on Plant Growth
1. Defining the question:
I am curious about how different levels of sunlight affect the growth rate of common bean plants. Specifically, I want to understand whether plants grown in full sunlight grow faster or healthier than those grown in partial or no sunlight.
2. Gathering information and resources:
Based on prior observations and knowledge from biology classes, plants require light for photosynthesis. I researched scientific articles indicating that light intensity can influence plant growth rates. I also reviewed guidelines on growing plants with varying light conditions.
3. Forming an explanatory hypothesis:
I hypothesize that plants exposed to full sunlight will exhibit faster growth and healthier leaves compared to plants kept in partial or no sunlight. The prediction is that increased light exposure will correlate with increased biomass accumulation.
4. Testing the hypothesis:
To test this, I will set up three groups of identical bean plants. One group will be placed in full sunlight, another in partial sunlight (morning sun only), and the third in darkness (inside a closet). I will measure plant height, number of leaves, and overall health weekly over four weeks.
5. Analyzing the data from the test:
After four weeks, I will compare the growth measurements across the three groups. I expect the full sun group to have the greatest height and leaf count, the partial sun group to have moderate growth, and the dark group to show minimal or no growth.
6. Interpreting the data and drawing conclusions:
If the data confirms that full sunlight plants grow significantly more than the others, it supports my hypothesis. If not, the hypothesis may be falsified. Alternative explanations might include soil quality or watering frequency influencing growth, so I will control these variables.
7. Publishing results:
I plan to write a report and submit it to a local science magazine or school journal, where it can be peer-reviewed and shared with others interested in plant biology and science education.
8. Retesting and field reaction:
Other scientists or gardeners might find the study interesting, as it provides clear evidence about light's impact on plant growth. They might replicate the experiment with different plant species or introduce variables such as fertilizer. If results differ, they may propose alternate explanations like genetic differences or pests, but the current findings should reinforce the importance of adequate sunlight for healthy plant development.
