STEM Tuesday– Extinction– In the Classroom


Extinction is a tough theme. I struggled with my emotions a bit as I read through books from this month’s list. All the books I read balanced the threat of extinction with hope for staving it off. This included providing actions individuals can take to make a difference to species threatened with extinction. More on that below. First, here are the books I read. All were exceptionally well done and worth the read.

Champion, The Comeback Tale of the American Chestnut Tree
by Sally M Walker

I married a guy who loves trees, so it’s no surprise that this book caught my eye. Plants and trees often seem forgotten when discussions of endangered or extinct species arise. This book covers the importance of the American Chestnut in American history and culture and how it was almost wiped out. Then it looks at the different ways scientists are trying to save this tree from extinction.

Giraffe Extinction: Using Science & Tech To Save the Gentle Giants
by Tanya Anderson

My sister loves giraffes, so of course I had to read this book. I learned so much about giraffes that I didn’t know! This book also includes great descriptions about things like the IUCN Red List and taxonomy.

by Rebecca E. Hirsch

I love birding and am a Scouts BSA Bird Study merit badge counselor. I’ve also been rewilding my yard, repopulating it with native plants. Some of my favorite visitors are the different types of bumblebees that visit our native wildflowers. Given that, this duo of books from Rebecca Hirsch were must-reads for me. They gave me a greater understanding of what’s driving bird and bumblebee species to the edge of extinction, along with things I can do to help bring them back from that edge (some of which I was already doing, like planting native plants).

 

Learn Some Terminology

When you learn about threatened and endangered species, you hear lots of new terms related to them. And that’s in addition to the levels used in the IUCN Red List. Now would be a great time to find out what the following terms mean and how they relate to extinction.

Terms to explore: extant, extirpated, extinct, invasive, naturalized.

(Hopefully I didn’t forget any big ones.)

Explore Your Local Area

Endangered and threatened species classification is done on many levels. Explore what species are threatened or endangered in your neck of the woods. Have each student pick one to explore further.

What is its natural habitat? Why is the species threatened? How many are still in existence in the wild? What is being done to protect the species?

Have students educate each other about what they’ve found. Then have them pool their information in the following activity.

[If you’re having trouble finding this information, start with your local parks, Fish & Wildlife, Department of Natural Resources, or conservation organizations.
Some New Jersey resources are:
NJ Fish & Wildlife (Department of Environmental Protection) – https://dep.nj.gov/njfw/wildlife;
Conserve Wildlife Foundation of New Jersey – http://www.conservewildlifenj.org;
the U.S. Fish & Wildlife Service NJ Field Office – https://www.fws.gov/office/new-jersey-ecological-services/species.]

Graph It Out!

If you read about multiple species, you’ll notice repetition among the things that are driving them towards extinction. It’s not just one thing, either. Usually, there are multiple factors working together to drive species to die out.

Have each student research a different threatened or endangered species (or even one that has gone extinct). Find out what factors are/were negatively impacting the species.

Combine all the collected information into a graph or chart to show the most common factors driving species to extinction. Is it habitat loss, fragmentation, pesticide use, or something else?

What would be the best way to illustrate this? A bar graph? A pie chart? Something else?

Take Action

Once you’ve learned about lots of species needing help in your area, you’ll probably be a little depressed and/or scared. The best thing to do is to take some action that will make a difference to those threatened species. Look for ideas in the books on the booklist or in the other resources you’ve accessed.

A few ideas include:
Stop pesticide use on lawns and fields. This could include lobbying your local school board or town/county/city council.
Create a native plant garden or pocket meadow. (If you search the internet, you will find lots of resources to help.) There are lots of local Native Plant Society chapters that could help with this.
Participate in a Community Science program to help collect data on species – see the June 2022 post to help with this.

Be a Citizen Scientist and help NASA GLOBE Measure Trees!!

NASA GLOBE Tree Challenge logo

Calling all teachers, parents, homeschoolers– here is a way to help the environment!

 

Have you ever looked up at a tree and wondered just exactly how tall it really is?  How did it grow that high? And does the height of the tree really affect the environment? YES!

 

Tree height can help scientists determine not how healthy the environment is but also let them know how much carbon is being pulled out of the atmosphere.

 

Sounds, cool, doesn’t it?

 

NASA GLOBE  (Global Learning and Observations to benefit the Environment)
is a program that encompasses many different parts of the environment. , NASA looks for help from the public
to gather data across the Earth and then compares it with data that it gathers from satellites in space.

 

There is a GLOBE Clouds program where you can identify clouds  Clouds

 

    and a podcast for that
Cloud Watching podcast image

 

and also a GLOBE TREES program  

 

NASA GLOBE Trees needs  YOU! 

 

Join the NASA GLOBE Trees Challenge 2022: “Trees in a Changing Climate” from 11 October through 11 November

NASA GLOBE Trees Challenge 2022

 

From the NASA GLOBE website:

Help us estimate the number of trees that make up your area and contribute to tree and climate science by sharing your observations of trees.

 

How to participate:

  1. Download the GLOBE Observer app and register an account.
  2. Estimate heights of trees around you using the Trees tool.* (Remember to always be safe and follow local guidelines when observing.)
  3. Optionally, use a tape measure to add data about tree circumference to your observations.
  4. Comment in the field notes about any changes you know have occurred in the area you took the tree heights, and if the trees appear healthy, unhealthy, or dead.

 

 

To learn more about the program and hear from Brian Campbell, NASA Senior Earth Science Outreach Specialist at NASA’s Goddard Space Flight  Facility in Wallops Island, Virginia, USA, take a listen to the podcast below. Brian is also the Trees Around the GLOBE Student Research Campaign Lead and the Trees Science Lead for the NASA GLOBE Observer citizen science program. Brian works with local to international students, educators, citizen scientists, and researchers in over 100 countries.

 

To hear the podcast, just click on the image:

 

Once you upload your tree data you can see if NASA has captured a picture of your tree from their satellite in space! You can compare the information from both sources and see how accurate the satellite data is.

The challenge runs from October 11th to November 11th, 2022. So get your apps ready and go out and MEASURE SOME TREES!!

 

This is a great challenge for teachers, classrooms, kids, families, parents, and grandparents. Let’s get TONS of data for NASA GLOBE. Then we can help figure out how healthy our planet really is.

STEM Tuesday — A River Runs Through It– Author Interview

Welcome to STEM Tuesday: Author Interview, a repeating feature for the fourth Tuesday of every month. Go Science-Tech-Engineering-Math!

Today we’re interviewing Patricia Newman, author of the new book A RIVER’S GIFTS: THE MIGHTY ELWHA ROVER REBORN, illustrated by Natasha Donovan. “An illuminating glimpse at the Elwha River and its gifts…Beautifully illustrated and informative,” says Kirkus in a starred review.

Andi Diehn: I love how this is a story of scientific progress told alongside the story of a culture, the Strong People, who witness the destruction of their river and work for its return. How did you find a balance between discussing the engineering of the dams and story of a people?

Patricia Newman: When I write about the environment, I always discover a wonderful overlap between science, history, culture, and current events. This connection to all parts of our lives draws me to nature writing. That said, I do have to make some decisions regarding the pacing of the story—some details are omitted while others are expanded upon. During the research phase of A RIVER’S GIFTS, I took my lead from my experts who co-mingled science and culture. In this region, it is impossible to talk about the Elwha River without also considering its cultural significance.

AD: What inspired you to write this particular story?

PN: My husband came home from work one day with a book idea after a conversation with one of his colleagues. After 38 years of marriage, my husband has developed exceptional book-idea antennae! The story had it all. Nature. Environmental justice. Water (a happy place for me). A conservation success story. All those pieces and their assorted layers made this idea a go.

AD: You do a great job describing the tension between some forms of progress – such as electric lights in homes and businesses – and the adverse effect of that progress on the natural world. What are some other examples of progress versus environmental health?

PN: I remember an economics professor in college explaining the term “opportunity cost”—what we give up by choosing one thing over another. Life is filled with opportunity costs. I don’t blame the early Elwha River settlers one bit for preferring a life with electricity over a life without it. I grumble when my electricity goes down for a few hours! But we also need to include nature into our calculations when we make decisions.

For instance, at the time the Elwha Dam was built, Washington had a law stating all dams must include fish ladders to allow salmon to pass. For some reason, government officials waived this law for Thomas Aldwell, builder of the Elwha Dam. Why? No one knows. And in hindsight, this waiver is particularly maddening because the law was written with consideration for nature.

Including nature in our plans probably won’t be the easiest or cheapest solution. Look at gas-powered vehicles. They’re convenient. They’re fast. But they come with an enormous opportunity cost. We’re sacrificing clean air and clean water. Our temperature is rising because excess CO2 left over from burning fossil fuels clogs the atmosphere. Arctic ice is melting as the ocean warms. Heat waves, fires, and droughts dominate the news.

Way back, we chose leaders who prioritized progress over nature. Now, when we elect new leaders, we need to consider balancing progress and nature to live more sustainably.

AD: Are there other dam dismantling success stories? Any examples of dam dismantling gone wrong?

PN: Dams themselves aren’t evil. They provide a clean source of energy for millions of people, but they do come with consequences. River flow and flood patterns change. Fish populations change. Changes in the river channel change the surrounding forest. Dams are man-made structures that interfere with the natural functions of nature, functions we often don’t fully understand.

Every dam removal is a success story because we return a river to its free-flowing state to manage flooding, resupply the water table, manage wildlife populations, and nourish the ecosystem. Nearly 1,800 dams have been removed in the U.S. since 1912. I don’t know of any dam removals gone bad, but I do know of several projects that, like the Elwha River Restoration, are taking years of legal wrangling and governmental maneuvering.

AD: These illustrations are both gorgeous and scientifically fascinating! Why did the team think it important to add labels to the different species?

PN: I’m glad you like Natasha Donovan’s work. She is Métis and lives in the general area of the Elwha River, so she was able to create from her heart. In her art I can hear the river flow and feel its power.

In my original proposal, I provided lists of trees, plants, and wildlife for possible spot illustrations in the margins. I thought readers would feel the scope of this project if they knew about the vast array of biodiversity being saved. Art Director Danielle Carnito had the brilliant idea to add the labels directly to Natasha’s illustrations. The small but informative labels gave Natasha a lot more room for her gorgeous art.

AD: Why include real photographs of the dam being built and dismantled, not just illustrations?

PN: As a nonfiction author, “real” is important to me. Illustrations seemed a better fit for A RIVER’S GIFTS overall because the book begins back when the river first formed tens of thousands of years ago. But I worked from photographs. My research files are loaded with photos that show a sense of time and place. I think the photos provide a telling look at the size of these dams and the engineering magic that occurred to build them.

AD: One of the takeaway lessons from this book is that it’s never too late. We can undo past mistakes once we know better, such as dismantling dams. Why is this important to explore in children’s literature?

PN: We are all under attack by environmental headlines that spew gloom and doom. That’s why I write about our CONNECTION to nature. I want my readers to understand how it sustains us and how our habits affect it. With understanding, comes a sense of gratitude for nature and all its gifts. With gratitude comes action. And with action comes hope. Nature will heal itself if we move out of the way. We just need to learn which way to jump.
