In this project, you will plan, conduct, and write up a research project just like professional biologist do when working at colleges or universities and you will develop both a testable research hypothesis and a null hypothesis.


You will conduct a literature review to make sure you understand your chosen topic and know what work has already been conducted on this area of biology. From the information you find you will develop a problem statement that will allow you to identify hypotheses capable of being tested to answering your problem. In order to answer your problem statement, you will develop both a testable research hypothesis and a null hypothesis.


What do we know about it? Start with a description of the subject (in your own words), and then provide a historical perspective on the work already done. You should also include potential benefits, uses, and examples. The introduction should not express your personal views or thoughts; instead, it should summarize in your own words the work already done on this topic.

What is the main question/problem statement?

Describe the problem that your experiment is designed to answer. Your problem statement should be clear, insightful, and relevant to the study of biology.
What is a possible answer to the question? The purpose of the experiment is to determine if the hypothesis is true or false, not to back up your initial thoughts.


You would like to know if your hypothesis is true so you must design an experiment that can be conducted at home to test your hypothesis. Remember that you must identify and control all the variables involved in your experiment. You also need to consider the number of treatments, and replicates, needed to produce a data set that can be investigated using the appropriate statistics to determine whether to accept or reject your null hypothesis.

Describe the experiment/research possibility.

What materials will you need for this experiment?

What are the variables you will be looking at?
1. independent variables
2. dependent variables

Statistical Analysis:

A number of statistical tests are available for testing your data. As this is not a statistics course and we have limited time you will analyze your results using a t-test. This commonly used statistical test calculates the probability that the mean of one group is not different than the mean of a second group. Your experimental design should, therefore, fit the basic requirements of the t-test.

Once you have considered all of the above, you will need to write your Methods. Remember, this section should ONLY describe the materials you use and the experiment you perform. It should be written in first person and be thorough enough that someone else could exactly replicate your experiment.

Your completed report will be submitted to Turnitin. Direct quoting of material and copying and pasting will lead to a recorded grade of “F.”

Some plants have the capacity to inhibit the effects of other plants. This element is beneficial and it is known as allelopathy. This process works by the plants discharging chemical compounds into the environment through different approaches that include volatilization, percolation or through decaying of plants. Currently, studies have identified activities related to allelopathy of plants in relation to their effects on weeds as well as the effect of allelopathy crops on other crops. In this case, the most significant economic benefit of allelopathy is the capacity to suppress weeds. Traditionally, agriculture has heavily depended on chemicals to control the spread of weeds. However, growing attention to different challenges on the environment that has had a direct implication on the general wellbeing of human beings has promoted research in using organic agriculture (Machado, 2007). ...
