Shortening food chains: Circle of Life or Human Interference?


The article discussed this week can be found below:

Researchers show that smaller area means not only fewer species, but also, shorter food chains. (2013, November 25).  News Medical Life Science. Retrieved from: https://www.news-medical.net/news/20131125/Researchers-show-that-smaller-area-means-not-only-fewer-species-but-also-shorter-food-chains.aspx

            To continue our knowledge on determining which text is appropriate to introduce our students to, Pearl and I have chosen to continue with the topic of food chains due to its versatility. For the past two weeks, the overall message of the articles we have used have had a heavy focus on how our actions have influenced the world around us. Specifically, these articles presented the problem that animal habitats are not how we have once known them to be. Where our actions such as littering, and emission of greenhouse gases have nearly devastated the primary producers that are included within the aquatic food chain. However, Pearl and I were hoping to find an article that would bring up more concepts for our students to keep in mind when one is thinking about the different components that give rise to changes in the food chain. Given that Pearl is more experienced in teaching life science and presenting literature, we have decided to go with an article she selected entitled “Researchers show that smaller area means not only fewer species but also shorter food chains” (cited above) that was published thorough the news medical life sciences website. The one thing I like about this article is that there is an emphasis placed on animal behavior. This new focus will allow for students to learn a new component of life science while expanding their knowledge on how organism diversity can be linked to how these organisms behave in their environment.

            When I first read the article, I felt that the author grabbed my attention and brought a different perspective on how we as humans are heavily influencing the ecosystems that many living organisms call home. This article is structured in a way that is not chronological but utilizes the  . In addition, the text is structured and well organized with the use of headings to express the overall main idea of the paragraph prior to navigating to the next section of the text. For instance, the article opens with a brief overview that the “smaller area will mean not only fewer species, but also shorter food chains” (2013). Right away this grabbed my attention because when we talk about changes in the environment, typically the ideal of species becoming endangered or facing extinction was the topic at hand. However, this article also creates this positive correlation of the reduction of habitat area also leads to a reduction in the length of food chains. When the article referenced that the top predator will be the first to go, I found this to be interesting because I remember learning early on about how the primary producer becomes affected with changes to their habitat and that those changes then trickle down to the primary consumer (herbivores), secondary consumer (carnivore), and finally the top predator. This focus on a disappearance of top predators brings about an idea that the descending links in the food chain may behave differently with there not being as many top predators to look towards them as a food source.

           At the conclusion of my discussion with Pearl, we both came to the realization that this article is appropriate for both middle and high school students. The good thing about this article is that the overall diction of the text is very straight forward and would allow for our students to be given more challenging tasks when it comes to either guided reading questions or a type of formative assessment. Due to the simplicity of the text, I think that if I was to give this article to high school students, I should probably  When looking through the learning standards, I found that this article relates the most to the life science learning standards that reads as, “Design, evaluate, and refine a solution for reducing the impacts of human activities on the environment and biodiversity.” (Guilford, 2017).  One thing I liked about the text was that its simplicity allows for our students to be challenged more in their extension piece to assure they truly connect with and comprehend the text they have just read. Once our students are able to determine the big picture of a text, they will be able to become more critical and concise thinkers.

         This week, we were tasked to provide our students with text that will allow for students to make extensions beyond the mere facts obtained from the literature. In order to accomplish this, I continued using the preparatory analysis of text (PAT) to be able to complete an analysis of the text from both the perspective of an educator and as a student. In my analysis, I felt that the overall density of information was concise and allowed for the reader to slowly intake information without becoming discouraged by information overload. In the second component of this assignment we are to assign our partners a strategy that can be provided to students to form extensions of the information they have read to build one’s essential knowledge. For this week, I assigned Pearl the double diary entries and Pearl assigned me the fact pyramid (Buehl, 2014). In the double diary entries, there are two components where one must find a quotation or textual evidence in one column and in the other discuss the importance of the selected text. I suggested the use of this strategy to Pearl because when I am analyzing text, the words that I highlight that had the greatest impact on me while reading tend to be the pieces of text that I can form and extension off of to discuss how a piece of literature relates to me and the world I live in. When using the fact pyramid, there are three components which include (from top to bottom) essential knowledge, short-term information, and background detail. For the essential knowledge, this is the main take home message the reader receives after reading a piece of text. In this part of the pyramid, I wrote island fragmentation leads to loss of top predators and the interactions they contribute to their environment. When moving down to the second part of the pyramid, I wrote the terms habitat and ecology because the second level of the pyramid serves the purpose of providing information that is used to contribute to one’s essential knowledge but may be forgotten about over time. In the bottom of the pyramid is the background detail and I wrote that one must know that the top of the food chain is symbolic of the top predator and the primary producer is going to be on the bottom of the food chain. I also wrote the terms ecology and animal behavior because if we want to conserve the planet and protect wildlife, then it is imperative that we can understand ecology which is merely how organisms behave with ones of their own kind and organisms belonging to different species.
        Overall, I think that the use of the fact pyramid would be a better option for extension of reading due to the idea of incorporating prior knowledge with the new information presented in the text to form a more concrete idea of a topic taught in class. This strategy reminds me of inquiry learning because I can see where each of the four phases of inquiry learning (triggering event, exploration, integration, and resolution) can be utilized in class to aide students in learning about food chains (Breivik, 2016). For instance, the triggering events can be a think-pair-share drill activity to get students thinking about the impact changes in the environment impact the food chains. The exploration is where I would supply my students with the article where students can highlight the main idea the author is trying to get across in the text. In the integration piece, students will use the fact pyramid to combine their prior knowledge with the new concepts they have learned to come to a resolution where students can devise a plan that can be used as a conservation effort to keep islands and other habitats together.

  1. Hi Breanna!
    I agree with you on how engaging an article is if it begins in a way to grab your attention immediately. The past two articles I have read, began with a brief story and I was immediately engaged an accessing my prior knowledge from the scenario. I believe if you are engaged immediately then this shows that your students will be as well. I think your strategy this week sounds like an interesting ones for older students. How would you fit that strategy within your classroom specifically? Do you feel that the students would be engaged from the strategy and it would allow for better comprehension?

  2. Bri,

    I liked the article you and your partner chose this week because the text structure makes the article much more accessible for your students. Because the information is formatted into several small paragraphs, each with their own title, it breaks the text up into several major ideas that are easy to follow. I was interested to see that you thought fact pyramids were an effective reading strategy to extend student learning. In Bloom’s Taxonomy, this would meet a high level of thinking. If students can evaluate information and distinguish essential ideas from other ideas this hits a level 5 of understanding (Zhou & Brown, 2015). However, since this text was already broken up into several organized paragraphs, I felt like much of the work was already done for the reader. If I were to do this activity as a student, I feel like I would be rewording the paragraph titles as my essential knowledge. I also wish there would be some peer evaluation or collaboration once each individual student created their pyramids. You could alter this assignment to be more closely related to paired summarizing, where students create their own summary, read a partner’s summary and compare and contrast the findings (McLaughlin, 2015). We add more listening and speaking practice when we get students to work in small groups.

    1. Hi Vince,
      Those are interesting ideas about how to expand on the strategy. Teaching students how to work with text features, such as headings, are important when teaching them how to be metacognitive with the content area texts they encounter.
