Pipe Cleaner Constellations

Kirsten W. Larson
This is a picture of pipe cleaners, star beads, and constellations.

Looking for a simple activity to accompany THE FIRE OF STARS? Check out this pipe cleaner constellation activity from 123 Homeschool 4 Me. We did this activity at my Barnes & Noble book launch, and it was a huge hit.

What you need:

What you do:

  • Pick a constellation printable.
  • Slip on the the appropriate number of beads.
  • Space out the beads, bend, and shape until your constellation resembles the one on the card.

Note that some constellations, like the Northern Cross, may require adding a second pipecleaner plus trimming with the scissors. These more complex constellations are fun for older kids. Simpler constellations like Coma or the Big Dipper are easier for preschoolers.

We’ll make pipecleaner constellations at my upcoming event at Barnes & Noble Peninsula Town Center in Hampton, VA on Aug. 5 at 11 a.m. If you are in the Tidewater area, join me. Learn more here.

STEM Activity: The Life Cycles of Stars

Kirsten W. Larson

Cecilia Payne’s groundbreaking discovery of what makes the stars paved the way for more star discoveries, including how stars are born and eventually die. That’s right, just like humans, stars have life cycles.

To learn how stars are born, read THE FIRE OF STARS with your students, including the back matter, A STAR IS BORN. Then study how stars’ lives end using these resources:

Next, invite your students to use what they’ve learned to fill in this star life cycle worksheet.

Mnemonics: Crafting creative memory aids

Kirsten W. Larson

A mnemonic is a clever and creative way to remember something, using a pattern, sentence, or phrase. You may use “ROY G BIV” to remember the spectrum of light: red, orange, yellow, green, blue, indigo, violet. Some people use “My Very Educated Mother Just Served Us Nachos” to recall the order of the planets starting closest to the sun: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

Recalling Star Classifications

In Cecilia Payne-Gaposchkin’s day, people used a mnemonic to remember the classifications of the stars, a system developed by Harvard’s Annie Jump Cannon. The color classes from hottest to coolest are O (blue), B (bluish), A (blue-white), F (white), yellow-white (G), orange (K), and red (M), as you can see in the image below. You can learn more about star classification at ScienceNotes.org.

This image shows the colors of the stars from hottest to coldest.

In those days, they used the mnemonic, “Oh, Be A Fine Girl Kiss Me” to remember the star classes. Today, some have updated it to “Old Bob Always Favors Green Ketchup More.”

You try

Can you think on another mnemonic to remember star classes?

Is there something else you want to remember? Could you develop a mnemonic to help you remember it? Now draw a picture to accompany your phrase.

The Fire of Stars

Learn more about astronomer and astrophysicist Cecilia Payne-Gaposchkin, who discovered star ingredients, in THE FIRE OF STARS. The helped lay the foundation for future scientists to discover why stars have such tremendous energy and why they burn so brightly.

Make Your Own Stellar Scene

Kirsten W. Larson

Each month, I’ll spotlight a book-based educational activity teachers and homeschooling parents can use with their students. This activity was created by FIRE OF STARS illustrator Katherine Roy. It appears in our educators’ guide, which you’ll find here.

Make Your Own Stellar Scene

The James Webb Space Telescope was launched in 2021 and is the largest optical telescope in space. It is capable of producing high-resolution photographs of ancient, remote galaxies like no telescope before it. Show images that the James Webb Space Telescope has taken to the class. 

  1. What are the different colors and shapes in these photographs?
  2. How do the photographs make them feel?
  3. How big or small do you think these scenes are? 
  4. What marks or textures could be used to represent these scenes in a drawing? 

Explain that illustrator Katherine Roy used an old toothbrush dipped in ink and watercolor to represent the star storyline in THE FIRE OF STARS: The Life and Brilliance of the Woman Who Discovered What Stars Are Made Of. To make their own stellar scenes, students will need:

  • paper
  • old toothbrushes or paint brushes 
  • watercolor, paint, or ink 
  • water 
  • salt 
  1. Make a swirling circle in the middle of your paper. 
  2. Get a little more paint or ink on your brush and make bigger swirls. These are the gases orbiting your newly formed star.
  3. Try making some thick marks. Now try making some thin marks. What feels right to you? 
  4. Try adding spatter marks and salt to represent dust and particles.  

When the paintings are completed, display the paintings in a classroom gallery for their own view of the cosmos.

Constellation Projector

Kirsten W. Larson
This is a picture of author Kirsten Larson with the finished constellation projector.

Here’s an activity linked to THE FIRE OF STARS (Chronicle Books) perfect for the budding astronomer in your life. This constellation projector is simple to make with common household items. And the results are stellar, which you’ll see at the end!

What you’ll need

You will need: a flashlight, a toilet paper tube, tape, glue, scissors, sharp pencil, popsicle stick for spreading glue (optional) and constellation printable.

You will need:

  • a flashlight (or your phone flashlight)
  • a toilet paper tube
  • tape (washi tape looks really nice if you have it)
  • glue and a popsicle stick for spreading it if you want
  • scissors
  • sharp pencil
  • constellation printable, which you’ll find here at Homeschool 123 Homeschool 4 Me
  • Optional: construction paper or scrapbook paper to cover your toilet paper tube OR markers to color it.

Directions

This is a picture of Kirsten showing the constellations that have been punched and cut out.
  • Print out or copy the constellation printables on your printer, reducing them to 30 to 50% of the full size. You want the constellation to fit within the circle of the toilet paper tube.
  • Using the sharp point of the pencil, punch holes where the stars are on the constellation. Be very careful so you don’t poke yourself!
  • Cut a large circle around the constellation and and make little snips around the circumference so the edges fold more easily over the toilet paper tube.
  • Put glue on the edges where you’ve snipped, and glue the constellation over the toilet paper tube.
  • Cover the paper edges with washi tape or plain old scotch tape if you don’t have it.
  • You can decorate your toilet paper tube with markers or construction paper, and write the name of the constellation on the side.
  • When you are finished, go into a dark room or closet and put your flashlight inside the toilet paper tube to enjoy your constellation.

#MentorTextMoment: SWEET DREAMS, SARAH

Kirsten W. Larson

As part of my writing process, I read dozens of books by other nonfiction authors. When I read, I make notes about the craft choices authors make in terms of voice, structure, POV, and other unique elements that add up to amazing books. I recently decided to share my notes (in a searchable format), so teachers and fellow writers can see what I find new and noteworthy. Please feel free to share your thoughts in the comments below.

The Book:

SWEET DREAMS, SARAH

Author/Illustrator: Vivian Kirkfield, illustrations by Chris Ewald

Publication Info.: Creston Books, 2019

Ages/Grades: grades 2 to 5

Category: biography, STEM, STEAM, third-person POV

First lines:

Before the Civil War, Sarah obeyed her owner.

Hurry up.

Eyes down.

Don’t speak.

Overview (from the publisher): “Sarah E. Goode was one of the first African-American women to get a US patent. Working in her furniture store, she recognized a need for a multi-use bed and through hard work, ingenuity, and determination, invented her unique cupboard bed. She built more than a piece of furniture. She built a life far away from slavery, a life where her sweet dreams could come true.”

What’s noteworthy for authors and educators:

One of the most transformational moments in my own writing was when I started to think about the craft of writing picture books as poetry, not prose. As a beginner, I often equated writing nonfiction picture books with writing an essay, which resulted in long, plodding paragraphs. Yikes! In SWEET DREAMS, SARAH, Vivian Kirkfield, shows us the magic of occasionally using short sentences, more like poetry, to keep the story moving. (Her opening is a perfect example.)

Also notable is how she shifts between a traditional third-person narrator and Sarah’s own experience. The opening lines above provide a perfect example. “Hurry up. Eyes down. Don’t speak.” are clearly words that Sarah hears as she works, though we aren’t told this directly. Overall, Kirkfield’s third-person narration stays very close to Sarah, the main character, giving us glimpses into her thoughts.

A final favorite is this book’s topic: invention! I find biographies about inventors to be so useful for students, in terms of teaching them persistence and the value of a growth mindset. What was it that Edison supposedly said? “I have not failed. I’ve just found 10,000 ways that won’t work.” That seems to be the path of all inventors (and creators like writers too), and Sarah is no exception.

PPBF: PLANTS CAN’T SIT STILL

Kirsten W. Larson

TITLE: Plants Can’t Sit Still

AUTHOR: Rebecca E. Hirsch

ILLUSTRATOR: Mia Posada

PUBLICATION INFO: Millbrook Press, 2016

ISBN: 978-1467780315

SOURCE: review copy provided by publisher

INTENDED AUDIENCE: ages 5 and up

GENRE: nonfiction picture book

OPENING and SYNOPSIS:

“Plants don’t have feet or fins or wings, yet they can move in many ways. Look closely and you’ll discover that plants can’t sit still.”

From the publisher: “Do plants really move? Absolutely! You might be surprised by all ways plants can move. Plants might not pick up their roots and walk away, but they definitely don’t sit still! Discover the many ways plants (and their seeds) move. Whether it’s a sunflower, a Venus flytrap, or an exotic plant like an exploding cucumber, this fascinating picture book shows just how excitingly active plants really are.”

WHY I LIKE THIS BOOK: Hirsch turns conventional thinking on its head with this playful book. Plants may be rooted, but they can’t sit still, as Hirsch’s refrain tells us. She uses vivid verbs to explain the many ways plants grow, move, and spread, all the while reinforcing what plants need to grow: water, sunshine, and room. PLANTS CAN’T SIT STILL is both a great read-aloud and a wonderful addition to an elementary classroom unit about plants.

RESOURCES/ACTIVITIES:

  • See for yourself how plants reach and creep. Grow beans in a plastic bag. Find instructions here.
  • OutsideMom provides a lesson plan for learning how seeds move here.
  • Here’s a catchy tune about seed dispersal from Mr. R’s Songs for Teaching.

PPBF: Ada Byron Lovelace and the Thinking Machine

Kirsten W. Larson

 

TITLE: Ada Byron Lovelace and the Thinking Machine

AUTHOR: Laurie Wallmark

ILLUSTRATOR: April Chu

PUBLICATION INFO: Creston Books, 2015

ISBN: 978-1939547200

SOURCE: personal copy courtesy of Wallmark

INTENDED AUDIENCE: ages 5 and up (biography)

GENRE: nonfiction picture book

OPENING and SYNOPSIS:

“Ada was born into a world of poetry, but numbers, not words, captured her imagination.”

From the publisher: “Ada Lovelace, the daughter of the famous romantic poet, Lord Byron, develops her creativity through science and math. When she meets Charles Babbage, the inventor of the first mechanical computer, Ada understands the machine better than anyone else and writes the world’s first computer program in order to demonstrate its capabilities.”

WHY I LIKE THIS BOOK: STEM … women … need I say more? This book has been so well-reviewed, I’m a little late to the party. One thing that struck me was how Wallmark introduced the idea of one of Ada’s early inventions — a flying machine — and reintroduced the concept at the end to show Ada’s impact on the world: an early computer program called Ada, which allowed modern machines to fly. It creates a perfect circle and a satisfying read.

Summer Fun-Coding Class

Kirsten W. Larson

Screen Shot 2016-06-14 at 3.46.46 PM

We’ve all become a little frustrated trying to program our Mindstorm robot because we don’t understand the basics of programming. So, one of my goals for this summer was to work through Code.org’s Code Studio, a series of free, online coding classes designed for kids and adults so we can learn the basics.

The basics???

Well, it’s been 2 hours today, and I can’t get the boys off the iPads. They are moving through the lessons so fast I lost track of their progress. It’s a good thing Code.org keeps track though, so they can pick it up again later.

Finley even sent me one of the video games he created. Here’s the game if you want to check it out. (Note: I have not figured out how to win this one. Finley tells me not to move left or the Stormtroopers will appear and kill me.)
