Findings: Green Crab Male/Female Ratio

Students at Bath Middle School went to Reid State Park to collect crab trap data. This study was conducted because we wanted to find out about the crab population. We went on Oct 24th, 26th, 27th and 28th.
We used legal crab traps and sardines in oil, and also did a catch and release experiment and recorded data on the crabs we caught. I made three pie charts for 2015, 2016 and 2017 on the female and male population. The graphs show that over the years the female population has declined and the male population has risen. Currently, the green crab is a huge problem in the marine ecosystem. We need to find a way to get rid of this crab before the marine ecosystem is destroyed.

Comments

Not accepted for publication: As a reader, I'm interested in the relationship between clams and green crab and hoped that relationship is clearly made in this study. The sources aren't perfectly cited, but I understand that the prior research has shown a clear indirect relationship between number of green crabs and number of clams. Great intro! The methods don't clearly connect to the ideas presented in the introduction. The relationship is between number of green crabs and clams, so I was looking for a population count of green crabs and a population count of crabs. Graph is straightforward and labeled. Very close, but needed the clam data to focus the research to answer the questions posed in introduction. Loved the study! Keep going!

We gave this article 18.5 out of 20.
You included useful background info and found reliable sources. You didn't state a question clearly. You have made a prediction about the clams but not the crabs.
Methods has a clear explanation. We don't know why the color matters so can you explain that?
You made and explained the graphs well.
The conclusion has a clear explanation and interesting details.
You could improve spelling and proofreading.

Hi! This paper is an overall good article, and is worth consideration of publishing. These are some points that you should check over and improve this paper.

- Go back and spell check, Spelling and Grammar issues

- Add in possible claims to your conclusion created from your data, and explain how you ruled them out.

- Make the Research question a bit clearer in article.

- Possibly change title to fit article better, article dose not talk a lot about the Male/Female ratio and more of the population.
