STEM Tuesday– Invasive Species — Writing Tips & Resources

Looking at Language

When it comes to studying the use of language, this month’s topic “invasive species” is a prefect. Just take a look at the word “invasive.” What emotions does it conjure? In what other contexts have you heard that word used? Would you consider the term to be objective or subjective?

In the STEM disciplines, educators work hard to help students understand the value of objectivity. We all want engineers designing bridges to take an objective approach to measurement! When studying the natural world, objectivity helps us uncover truths unhampered by personal biases, emotions, and beliefs.

But no human is perfectly objective. To promote better practitioners of STEM, we must help students develop the intellectual tools to think critically about their own and other’s biases. An inquiry into the language used in STEM books is a great way to introduce that. It’s also a great way to learn more about writing STEM texts.

Reading STEM books we gain more than facts; we have opportunities to understand communication strategies as well.  Through studying these texts, we can learn to parse out bias in statements. When we extend our personal study with discussion, we can explore more complex topics such as perceptions of others, understanding nuance, and author’s purpose.

Titles Talk

Take a look at just the titles:

  • Science Warriors: The Battle Against Invasive Species, by Sneed B. Collard III
  • Tracking Pythons: The Quest to Catch an Invasive Predator and Save an Ecosystem, by Kate Messner
  • Invasive Species In Infographics By Renae Gilles

Read each title and jot down a few words about the feelings it evokes in you.

Do different titles evoke different emotions? If so, try to identify the words that led you to those reactions?

Take a look at their table of contents. If you don’t have access to the physical books, you can view table of contents here for Science Warriors, here for Tracking Pythons, and here for Invasive Species In Infographics. List the emotion that comes to mind as you read each chapter title. Do you notice any patterns?

Digging Deeper

Now, select one book to dig into. Feel free to select one from this month’s list or a nonfiction title of your choice.

“What” questions to ask:

  • What words in the text evoke emotions?
  • Create a list of emotional words from the text and rank them on a spectrum from strongest to weakest. Compare your list to that of someone else also studying the same text. Discuss your differences.
  • Does the emotive language always support the same point of view?

“When” questions to ask:

  • In which parts of the sentence/paragraph/chapter/book is emotive language used most frequently?
  • Can you spot any patterns in the use of emotive language (location, sequencing, etc.?

“Why” questions to ask:

  • Why might an author use emotive language in this passage?
  • Pick a few words that strike a chord in you. Why does that word cause that reaction?

“How?” questions to ask:

  • How obvious is the emotive language?
  • How did the author use language to support a premise?
  • How could you re-write a sentence to be more objective?

 

Balancing it Out

Now that we understand how authors are intentional in their use of specific words, let’s think about other techniques. Opinion, bias, and subjectivity are expressed or balanced using techniques that reach far beyond word choice. What other techniques did you notice in this book? Were specific techniques are used to balance bias or convey objectivity?

 

Your Turn

  • What is your opinion about this use of emotive language?
  • Is it warranted?
  • Was the author “fair” in their use of language?
  • Is your response based on your opinions about the topic?

Thanks for getting curious about the use of objective language in STEM books!

STEM Tuesday — Invasive Species– In the Classroom

Nature can fall out of balance when invasive species enter a new ecosystem. What happens to that ecosystem and its native species when that happens? This month’s STEM Tuesday theme focuses on this important issue and how scientists are studying the effects of invasive species. Here are a few books from our STEM Tuesday list and ways to explore more in the classroom.

Tracking Pythons : The Quest to Catch an Invasive Predator and Save An Ecosystem by Kate Messner

This book takes readers out on a python patrol where we meet a team of scientist studying the invasive snake. Readers also meet other invaders of the Florida Everglades. There’s technology (radiotracking), python CSI, snake autopsies (called necropsies) and a wonderful series of sidebars highlighting “How to Catch a Python.” Great photos and a Most Wanted invasive species list add interest.

Classroom activity: The Florida Fish and Wildlife Conservation Commission is trying to save the Everglade ecosystem by removing invasive species and encouraging people to report sightings of invasive species. Have students visit the website page about making a report: https://myfwc.com/wildlifehabitats/nonnatives/report/. Ask students to research the invasive species of Florida and then create a report using the elements necessary to make it a credible one. Students can share their reports, adding some information about why that species is causing harm to the Everglades ecosystem.

 

Science Warriors: The Battle Against Invasive Species by Sneed B. Collard

Each of the four chapters focus on scientists studying invasive species. We meet brown tree snakes and zebra mussels, red fire ants taking over Texas, and the Melaleuca (paperbark) tree that was brought to the US and planted to stabilize soil. We see scientists doing field research and working on biological controls for invasive species. Includes a “Guide to Stopping Invasive Species.”

Classroom activity: Have students choose an invasive species from the book to study more. Then ask them to create a Venn diagram to compare and contrast the species’ native habitat to its invaded habitat. How are the two habitats different? How are the two habitats similar? Ask students to consider why that invasive species found the invaded habitat so hospitable and discuss with the class.

 

Alien Invaders: Species That Threaten Our World by Jane Drake & Ann Love

Each examination and image of an invader and their devastating effects worldwide is accompanied by a sidebar listing their alias, size, homeland, method of invasion, and line of attack. Besides the commonly known invaders, such as the starling, rat, and Kudzu, the book examines humans, walking catfish, yellow crazy ants, water hyacinth, mosquitos, and avian flu. Detailed sections on “Who Cares?,” “Volunteers,” and “Lessons Learned” expand the information into actions everyone can take to prevent, control, or help eliminate invaders.

Classroom activity: Ask students to research an invasive species not found in the book. Then have them create a profile of the species, just like what is in the book. The profile should include an image, alias, size, homeland, method of invasion, and line of attack.

 

Plants Out of Place (Let’s Explore Science) by Courtney Farrell

First, we learn what native plants are and their role in the food chain. Following chapters discuss introduced plants and how invasive species threaten the balance of ecosystems. Sidebar “mini field guides” include descriptions and range maps for some species of interest. In addition to discussing control methods, the author shows alternative uses, such as using kudzu vines to weave baskets.

Classroom activity: See if students can find an invasive plant species right in their own backyard or neighborhood. They should research invasive species of their area and then go on an invasive plant species hunt. Students can take a photo of the plant or sketch it in a journal. Then they can document the place where it was found and the number of plants found at the location. After a few finds, students can share their invasive species journal with the class.

 

 

Here are a few more general invasive species activities to try:

Hope these activities and resources get your students excited to learn more about invasive species!

 

Karen Latchana Kenney loves to write books about animals, and looks for them wherever she goes—from leafcutter ants trailing through the Amazon rain forest in Guyana, where she was born, to puffins in cliff-side burrows on the Irish island of Skellig Michael. She especially enjoys creating books about nature, biodiversity, conservation, and groundbreaking scientific discoveries—but also writes about civil rights, astronomy, historical moments, and many other topics. She lives in Minnesota with her husband and son, and bikes, hikes, and gazes at the night sky in northern Minnesota any moment she can. Visit her at https://latchanakenney.wordpress.com.

Invaders From Earth Series by Richard Spilsbury

There are six books in the series, highlighting threats from invasive reptiles and amphibians, plants, insects, mammals, birds, and fish and other marine species. Individual spreads detail specific organisms, highlighting how one species native to one area can be an unwelcome invader across the globe. End chapters go into mitigation and things kids can do.

Invasive Species in Infographics by Renae Gilles

Divided into four sections, this book focuses on what invasive species are, the damage they cause, and how to control them. The book models different ways of presenting information visually, using pie charts, bar graphs, timelines, flow charts, and annotated maps

Nature Out of Balance : How Invasive Species Are Changing the Planet by Merrie-Ellen Wilcox.

This book opens with a discussion of what invasives are and how they travel from one place to another. Two chapters look at ecosystems in balance and out of balance, the importance of biodiversity, and how scientists are studying invasive species. The final chapter explores whether – and how – we may want to rethink the word “invasive” and offers ideas for what we can do. Sidebars feature a who’s who list of invasive all-stars, from Asian carp to Zebra mussels.

Invasive Species (Ecological Disasters) by Lisa J Amstutz

Beginning with the exploration of an ecological plague in Australia – of European rabbits, the book demonstrates the varied effects and subsequent difficulties of eradication of invasive species. Using a conversational voice, photographs, and great sidebars, it examines (1) ways invasive species arrive – introduction (dandelion, goats), hitchhiking (small pox, rats), and escapees (pythons, pets); (2) circumstances that enhance their survival – Island effect, climate change & lack of predators; (3) specific examples or invasive land animals, plants, and fish; (4) the techniques and the cost of elimination and containment; and (5) prevention and citizen efforts. Strong back matter and sources notes round out this book.

What Is The Threat Of Invasive Species? (Sci-Hi: Science Issues) by Eve Hartman And Wendy Meshbesher

After defining invasive species and how they invade an ecosystem, the book evaluates the cost to native species and environments around the world from numerous plants, mammals, fungus, birds, amphibians, insects, and water invaders. It includes a detailed world map of invasive species and their effects. As well as “What Can You Do to Help?” and “Topics to Research” sections.

Animal Invaders (Let’s Explore Science) by Amanda F Doering

Focusing primarily on the US and Hawaii, the book briefly reviews habitats then discusses where invaders come from, the harm they do, and various methods tried to control them. As well as “Did you Know?” sections, this photo illustrated book contains maps, graphs, and diagrams.

Crab Campaign: An Invasive Species Tracker’s Journal by J.A. Watson

Five kids spend a summer in Maryland learning about and tracking the Chinese Mitten Crab. An invasive species that has actually been spotted in the Hudson River. As a Science Squad doing a community science project, the kids raise community awareness, research, track, and document their searches and ultimate discoveries. An engaging informational fiction.
