Debating Zoos and Circuses: An Argument about How Humans Should Live with Animals

Grade 6 English Language Arts

Learning Module

Abstract

In this Scholar Writing Project, students write an argument about the ways in which humans interact with animals through a study of zoos and circuses. They learn to support claims with clear reasons and relevant evidence.

Keywords

Zoos, Circuses, Arguments, Conservation, Entertainment, Education.

1. Overview

For the Student

Zoos and circuses are controversial places. Some people love them. Other people think they are cruel to animals. Still other people have mixed feelings. In this learning module, you are going to create an argument about zoos. You can take a ‘for’, ‘against’ or ‘mixed’ judgment response. However, whatever position you take, you should demonstrate you are aware of the range of views that are different from yours.

Focus Questions

In this learning module, we will focus on the following questions:

Are zoos and circuses cruel to animals?

Do the conservation and educational purposes of zoos justify their existence?

How do I write an argument to support claims with clear reasons and relevant evidence about whether zoos are for animal or humans?

Comment: Share one of your experiences of a visit to a zoo or circus, or of watching or reading something about animals in captivity. What do you remember most? Comment on another student's comment. Write @name first, inserting the student's name so they know you are commenting on their comment.

For the Teacher

Using a range of websites about zoos, students focus on the summarizing reading strategy to support their own research and writing about zoos. They also read and analyze the structure and language features of an argument about circuses. Then, they write an argument about the advantages and disadvantages of zoos, reviewing their peers’ arguments and revising their own argument for publication. Extension activities are also included using the picture book, Zoo by Anthony Browne.

Main CCSS Focus

W.7.1: Write arguments to support claims with clear reasons and relevant evidence.

2. Survey: Taking a Position on Zoos

For the Student

Learning Intention: To share your experiences and opinions about zoos in an online discussion.

Firstly, complete the survey. This survey focuses on your opinions of zoos. Then add your comment about zoos to Community.

Comment: What are your thoughts about zoos? Do you love them? Do you think they are cruel to animals? Or do you have mixed feelings? Post your opinions. Comment on the comments of 2-3 other students, debating points raised in their comments. You can also include images and web links that support your ideas with your comments.

Fig. 2: Cassowary Behind a Wired Enclosure

For the Teacher

This activity is to explore students’ background knowledge, experiences and opinions about zoos. To scaffold the comments in Community, use the survey that elicits students' opinions about zoos. This survey will prompt their thinking about zoos, enable them to extend their thinking, articulate their current position on zoos, and foreground some of the issues they will read about in the next activity. Their responses might be influenced by what they have read and viewed, and/or actual visits to zoos and circuses. The survey may also be repeated at the end of the module to see whether students’ opinions have changed.

Survey Results: Go to the Survey Tool in Publisher. Then go to Find a Survey => Already Distributed Surveys => Results.

To encourage students to add comments to the class discussion in Community, add teacher comments to stimulate thinking and to keep the online discussion focused. If needed, extra Community Updates may be added to build on students' comments more. Encourage students to post images and web links as well as comments in the updates; this may engage students more in the discussion.

CCSS Focus

SL.7.1: Engage effectively in a range of collaborative discussions with diverse partners on grade 7 topics, texts and issues, building on others’ ideas and expressing their own clearly.

SL.7.1c: Pose questions that elicit elaboration and respond to others’ questions and comments with relevant observations and ideas that bring the discussion back on topic as needed.

W.7.6: Use technology, including the Internet, to interact and collaborate with others.

3. Making Sense of Arguments in Favor of Zoos

For the Student

Learning Intention: To summarize arguments in favor of zoos and include supporting evidence.

Read the following websites about zoos and summarize the information each one presents in a comparison matrix. Summarizing is a reading strategy in which you identify the main ideas or say what is important in a text in your own words. It involves taking a larger selection of text and reducing it to its main points. A summary includes facts and does not include your personal opinions or judgments.

Work with a partner to discuss the main ideas and to find multimodal evidence in the text. Start by reading the title, headings and sub-headings, and predict what you think the website is about. Then look at the visuals and their captions and add points to your comparison matrix to summarize the information. Refer to evidence in the text as well as the visuals and audio.

Supporting Zoos: The following websites are in favor of zoos. You can find your own websites too, including a website of a zoo near you.Refer to evidence in the text as well as the visuals and audio.

St Louis Zoo. (2013). Lemur Triplets Induce Aahs at Saint Louis Zoo

BBC Nature. (2011). Happy Orangutans Live Longer in Zoos

The Department of Primary Industries, Parks, Water and Environment. (2013). Tasmanian Devils Welcomed at San Diego Zoo

Presenting Varied Viewpoints

New York Times. Zoos: News about Zoos, including Commentary and Archival Articles

Comment: Make a claim to support the thesis, ‘Zoos are a good thing’, and give some evidence to support the claim. Comment on one or two other students’ posts.

Summarizing Comparison Matrix

For the Teacher

In this activity students are immersed in online texts which support zoos. Their focus is using a summarizing reading strategy in order to identify arguments and evidence in support of zoos. The comparison matrix is used so students may record information from their research. It also helps to scaffold their summaries of the main ideas and to prompt them to find multimodal evidence for these ideas. Students may refer to their completed charts when they write their own texts. However, for accountability, students may also be required to submit them to the teacher through Submissions in Community.

Working in pairs will enable students to share the workload and promote collaboration and discussion, which in turn will deepen their understanding of their reading.

To provide extra support to students, post the following Overt Instruction Updates from the Writer’s Toolkit to Community if they need to focus on this aspect of writing at this time. Alternatively, individualized or small group support may be provided through structured mini-lessons.

  • Reading and Inferring
  • Vocabulary and Spelling

CCSS Focus

RL.7.2: Determine two or more central ideas in a text and provide an objective summary of the text.

RL.7.4: Determine the meaning of words and phrases as they are used in a text, including figurative, connotative, and technical meanings.

4. Making Sense of Arguments Against Zoos

For the Student

Learning Intention: To summarize arguments opposing zoos and include supporting evidence.

Work with a partner to discuss the main ideas and to find multimodal evidence in the text. Start by reading the title, headings and sub-headings, and predict what you think the website is about. Then look at the visuals and their captions and add points to your comparison matrix to summarize the information. Refer to evidence in the text as well as the visuals and audio.

Opposing Zoos: The following websites oppose zoos. You can find your own websites too.

For the Teacher

Assigning the project to the students at this stage is important to set clear expectations, and also so students understand how the activities on the structure and language features of an argument that follow will support them.

As students begin to draft their work, encourage them to use the Structure tool to organize some of the key ideas they have gathered from the reading and summarizing activities. Students should also refer to the rubric as a guide as they write in Creator. If necessary, look through the rubric with students.

6. Structure of Arguments

For the Student

Learning Intention: To identify the structure of an argument and the function of each part.

Now that you have received your Work Request to write an argument, this activity will support you to understand the structure of an argument text. An argument is a text that presents a point of view. It tries to persuade or convince others who may not yet have an opinion on a particular topic, or people who have an opposing point of view. Arguments are an important part of political debates, controversies about social issues, and scientific discussions - to name just a few of the places where arguments play an important role.

Look at Circuses Should Be Banned and complete the Structure of Arguments Chart, identifying the parts of an argument using the definitions. You may find more than one example.

Why Circuses Should Be Banned

Even though circuses entertain people all over the world, they should certainly be banned. The cruel treatment of animals when they are trained and perform, the unnatural behaviors, and safety issues for animals and humans, are all reasons why circuses must be banned.

Firstly, circuses should be banned because of their cruelty to animals. As circus animals have to perform tricks, they undergo extensive training. Trainers use whips, tight collars, bull hooks, electric prods and muzzles in order to train the animals and make them perform. In addition, many of the training methods such as punishment, isolation, removal of teeth and claws, and beatings are illegal under the laws of many countries. On the issue of cruelty, circuses must definitely be banned.

Similarly, the tricks that circus animals have to perform and their living conditions are not experienced by animals in their natural environment. For example, circus animals are penned in small cages so they have limited room to move. As a result, they do not experience what it would be like if they were living in their natural habitats. Animals, particularly large animals such as elephants, lions and tigers, need a lot of space to move around, not be chained up or only able to move a few steps in their cage. An elephant in the wild may travel up to 40 kilometers a day and lives in a social group. Chimpanzees and baboons also live in large, social groups in the wild. They do not perform tricks such as riding a motorbike or wearing human clothes in the wild. In short, the tricks that circus animals are forced to do in order to entertain people are unnatural behaviors.

Furthermore, circuses are unsafe for both humans and animals. Some animals have psychological suffering because of the cruel training and unnatural living conditions. They have become violent towards their trainers or audiences, resulting in physical injuries and even death for humans. For example, animals have been stunned or shot when they have become violent and/or later ‘put down’. The lives of humans and animals should not be sacrificed for circus entertainment.

On the other hand, some people might say that circuses are educational and they also provide jobs at a time when many people are unemployed. However, the jobs are not well paid and the performances of animals are unnatural, so they do not teach people anything about the natural behaviors of animals.

To sum up, there are many reasons to ban circuses such as cruelty to animals, they are not educational and they may be unsafe. Circuses are a thing of the past and they should undoubtedly stay in the past.

Comment: In earlier Updates you read information about zoos. Now that you understand the structure of argument texts, what is one claim and one counter-claim that you will include in your argument about zoos. Comment on at least one other student's comment.

Fig. 6: Horses performing in a circus.

For the Teacher

This activity supports students to explore an argument in a text about circuses to learn more about the structure of an argument. This text serves as a model of arguments for students to refer to when they write their own arguments about zoos.

The structure of an argument helps to achieve its purpose by:

  • Clearly stating an idea/argument through the thesis, and claims and counter-claims
  • Including evidence, examples and elaboration
  • Ensuring the writer does not go off on tangents which are not relevant to the main argument.

To provide extra support to students, post the following Overt Instruction Updates from the Writer’s Toolkit to Community if students need to focus on this aspect of writing at this time. Alternatively, individualized or small group support may be provided through structured mini-lessons.

  • Using the Rubric and Checker
  • Different Kinds of Argument Sentences
  • Paragraphs in Arguments

Students may refer to their completed charts when they write their own texts. However, for accountability, students may also be required to submit them to the teacher through Submissions in Community.

10. Contrasting Narrative and Argument through Anthony Browne's Zoo

For the Student

Learning Intention: To understand how images can present a point of view and how they can complement and/or challenge the written text.

Read Anthony Browne’s book, Zoo, published by Sunburst, 2002. This is a narrative, not an argument. However, it expresses a point of view about zoos in way that is quite different from argument texts. With a partner, discuss:

  • What did you think as you read the book?
  • What are Browne’s opinions about zoos? How do you know? Refer to words as well as images.
  • What are the differences between argument and narrative?

Comment: What do you think the author and illustrator, Anthony Browne, thinks about zoos? How can you tell from the language he uses? What telltale signs are there from the images he uses? Draw on some of the ideas of your discussion in your comments.

Fig. 10: Zoo by Anthony Browne.

For the Teacher

This activity is an extension activity and is optional in the learning module. Its purpose is to increase students’ understanding of argument texts by studying a narrative. The issue of zoos is raised in a quite different way by argument texts and narrative texts. Reading Zoo after looking at argument texts, is a way to highlight the differences between these two types of texts, despite similarities in the authors’ purposes. It is also a way to deepen students’ understanding of the issues involved in the topic about which they will be writing.

This is a very sophisticated picture book which presents strong arguments against zoos through the narrative of a family’s outing to the zoo and images of animals in zoos.

Browne, A. (2002). Zoo. New YorkFarrar, Straus & Giroux (Sunburst).

CCSS Focus

Anchor Standards: [Students] need to know how to combine elements of different kinds of writing—for example, to use narrative strategies within argument and explanation within narrative— to produce complex and nuanced writing.
