Findings Population of Green Crabs Male/Female and Color at Midcoast Maine Fall 2017

The research our 7th grade class is doing is to figure out why the crab ecosystem is going down, and why changes are happening in the ocean. Green crabs are killing our oceans that is why we need to do something about it. On October 23, 2017 our class went to Reid State Park to do our studies about populations of green crabs. At Reid State Park we used the set, catch and release method to do our research. My results show the population of male and female crabs along with the color of the green crabs. The results show how the ocean ecosystem is being impacted by these invasive crabs. My claim is that the populations are changing due to climate change. I believe this because the crabs migrate, die off, and repopulate due to the climate changing.

Hi FireBreathingDuckies,

You have some interesting conclusions, especially your consideration of the impact of climate change on green crab populations, but there is not a clear connection between the data that you collected and your research question. Why are the color and sex of the green crabs significant? With some more evidence to support your conclusions, you would have a great article. Keep investigating. We hope to see another submission from you!

~The Findings editorial board

Good explanation of the question and why it's important. You need to include sources and cite them.
Clear explanation of how you measured the crabs. You repeated some info.
Two graphs and a chart--helpful info
You have a clear claim but your crab data isn't used, just research. How does the color of crabs and size show evidence of climate change?

Add an abstract.
Introduction--Everything was connected to the main topic and you explained how your research connects to pre-existing work. You need to mention resources in the article. Try adding a prediction.
Methods--Your plan is clearly explained.
Results--You included multiple tables that make sense.
Conclusions--You made a clear claim but missing explanation of evidence--you need more explanation of how your data supports your claim.
