STEM Tuesday– Cephalopods — Writing Tips & Resources

Creativity and Octopuses!

The first of the cephalopods that comes to my mind is an octopus. To me, the metaphor of a multi-limbed being is in the multi-possibilities offered to apply to creative activities. Many arms and many legs and many muscular hydrostats mean that connections can go many ways. As my focus is STE(A)M, I began to run options though my head. I settled on music, research, and visual art (camouflage). Like a cephalopod, these are just three of the connected “arms” in the world of art. I make my case below.

Music and the Octopus.

One of the best known octopus songs is “The Octopus’s Garden,” by Ringo Starr (Richard Starkey) and recorded by the Beatles.

“I’d like to be under the sea
In an octopus’s garden with you”

 The cover of Octopus's Garden

The song is full of fun and joy. It is said that Ringo wrote the song after being told that octopuses collect stones and shells to make a decorative garden around their homes. Studies have shown that while we don’t understand their full capacity, octopuses have great intelligence.

Ringo is crediting them with a sense of artistry. Enough artistry to design and build a garden where …

“Oh, what joy for every girl and boy
Knowing they’re happy, and they’re safe”

Musicologist  Alan W. Pollack says:

The charm of “Octopus’s Garden” lies in its simplicity and complete lack of pretension.

Alan W. Pollack is an American musicologist known for having analyzed every song released by the British band the Beatles. Since this STE(A)M post is about science, I was wondering if a musicologist is considered a scientist. While Wikipedia describes it as “the academic, research-based study of music,” it employs of a number of fields of science, including psychology, sociology, acoustics, neurology, natural sciences, formal sciences and computer science.

The Octopus and Reasearch

Back to the idea of octopus as metaphor -it makes a great visual for research. Sometimes called a map or web for exploring possibilities, finding connections through random ideas is a superb tool for creativity. One can imagine the octopus, sitting in their garden, all arms reaching out to explore different places. There are no boundaries to using the mind this way.

Listening to “The Octopus’s Garden,” you find it is more than about a garden. It tells a story, shows emotion, incites curiosity, invites the imagination. Which is what good research should do. Musicology is sometimes considered to be a social science but many aspects, such as acoustics, musical instruments, and sound waves (and more), involve mathematics, materials science, psychology, and the list goes on. It one of many multi-armed disciplines.

In planning projects for kids, music and octopuses are intriguing ways to frame research and creative thinking. The investigation can be about any topic at all.  

Visual art and Octopuses

Octopuses have been the subject of artists since ancient Greece. Shown here is a lithograph from Jean Baptiste Vérany’s Chromolithographs of Cephalopods (1851). There is curiosity about creatures so unlike humans.

A historic lithograph of an octopus.

Members of the shell-less subclass of cephalopods (squid, cuttlefish, and octopuses) have the magic trick of color changing (yes, I know it’s a complicated process – not magic, but it is like magic to me). Some of their cells are capable of producing rapidly changing color patterns to match the surrounding areas or mimic other creatures. What a fascinating ability!

Doing art activities involving camouflage is a great way to improve eye, hand, and perception skills. And a real challenge. One needs to recognize shape, value, and colors to accurately reproduce them. Teachers Pay Teachers (link below) has a number of activities listed on their website. You don’t have to be an art teacher to use art projects as encouragement for students to do in-depth observational studies. With today’s fast-paced imagery of phones and games, people seem to be losing ability to focus. The value of practicing real observation can be time well spent.

Conclusion

Making connections is a large part of the creative process. It may appear this post strayed off topic, but it is an example of allowing the brain to find solutions that are new. Many inventions (such as the printing press) were the result of someone making an odd or unusual connection that ultimately led to a very useful solution. And, like learning to play music or becoming a good athlete, preliminary training paves the way. Anyone can practice connected thinking skills and use them for practical situations. Sometimes when I am doing research, allowing my mind to wander discovers materials better than what I was looking for.

Happy Connecting!

STEM Tuesday– Radio/UV Waves and Applied Physics — In the Classroom

 

Bright blue semicircular lines against a black background emanate from a central point to the left and the right. Text reads: Understanding and Using Radio Waves.

 

Understanding and Using Radio Waves
by Elizabeth Rubio

The focus of this book is on the portion of the electromagnetic spectrum called radio waves, but it also does a good job covering what the electromagnetic spectrum is. It also explains the difference between ionizing and non-ionizing radiation, which ties into the books X-Rays and The Radium Girls. The book also looks at the many ways radio waves are used.

 

White skeleton of chest and neck glows against a blue outline of a human body, against a black background. Text reads: Super Science Feats: Medical Breakthroughs: X-RaysSuper Science Feats: Medical Breakthroughs: X-Rays
by Alicia Z. Klepeis

This book briefly covers what x-rays are and what they can do.

 

Text reads: The Radium Girls: Young Readers Edition. Underneath, a surface covered in bright green holds a paintbrush, with green paint dripping off it, a bottle containing a green substance, a clock, and a skeleton.The Radium Girls
by Kate Moore

What happens when people are exposed to light waves emitted from radioactive material? This book tells the stories of a group of women who were exposed to radioactive radium through their work. This is not an easy read emotionally, but it tells a very important story.

Ever wondered how microwave ovens work? Check out this book for a brief overview of microwaves and how they are used to cook food.

 

A hand holds a cell phone. The image on the phone is a wifi symbol. Text reads How it Works: Wi-Fi.

Bonus Book: WiFi (How It Works)
by Janet Slingerland

This book provides an introduction to WiFi. It includes what radio waves are and how they are used to transmit signals, connecting devices through WiFi networks.

 

The electromagnetic spectrum (EMS) is one of my favorite science topics, and there are so many different things you can do with it. Here are just a few.

Search for Waves

Light waves are all around us all the time. Have students look around them to see how many different types of electromagnetic light waves they can find in their daily lives.

Give students an EMS chart like this one: https://www.ces.fau.edu/nasa/module-2/radiation-sun.php. Have them place things that use EMS waves onto the chart, in their proper location. For instance, everything we see falls into the visible light area of the EMS. Cameras/photographs could also be placed in this area.

BBC Bitesize has a great table that details different ways the various EMS wave types are used: https://www.bbc.co.uk/bitesize/guides/z79hvcw/revision/2

 

Explore Light

As explained in Understanding and Using Radio Waves, NASA uses radio waves to explore outer space. They have a great educators guide that covers the electromagnetic spectrum: https://www.nasa.gov/stem-content/the-electromagnetic-spectrum-unit. The activities involve building spectroscopes, instruments that allow people to separate and study light.

Exploratorium has another spectrograph activity: https://www.exploratorium.edu/snacks/cd-spectroscope

To explore how light is used to transmit audio, check out this activity:   https://www.exploratorium.edu/snacks/modulated-led. This would be great for a makerspace.

Another type of light that’s fun to explore is polarized light. This activity is also reminiscent of x-rays: https://www.exploratorium.edu/snacks/bone-stress

 

Have Fun with Luminescence

As described in The Radium Girls, people were enthralled by the luminescent beauty of radium. Here’s an activity that explores luminescence using a chemical reaction: https://www.exploratorium.edu/snacks/glow-up

You could also have fun exploring with a UV flashlight. This ties in with STEM Tuesday’s Bioluminescence topic from October 2024.

 

Consider OSHA

The story of the radium girls helped spur the creation of OSHA (Occupational Safety and Health Administration). Some legislators have called for eliminating OSHA. Have students explore OSHA – https://www.osha.gov – and what is does. After this investigation, do they believe OSHA should be eliminated or not? Have them write an essay or hold a debate to present their positions.

STEM Tuesday– Deserts — In the Classroom

stem tuesday logo

Deserts may seem dry and desolate, but they are thriving ecosystems filled with wildlife and plants that have adapted to survive harsh conditions. And even though school is out, these activities can help kids learn about the amazing desert and the unique life that thrive there.

Weird, Wild, Amazing! Desert: Exploring the World’s Incredible Drylands

by Tim Flannery; illustrated by Sam Caldwell

Welcome to the weird wildlife you might find in a desert, from ants to lizards, rattlesnakes to scorpions. Each of the seventeen animal profiles is filled with in-depth and sometimes bizarre facts that highlight issues like climate change and conservation or explain more about evolution and habitats.

 

 

 

Classroom activity: As students read through this fascinating title, tell them to create a comic book profile of one of the strangest animals described. They can use a notebook to record the animal’s name and basic information, and they can also record its “super powers”—its unique adaptations that help them survive in the desert. Students should give their creature a comic book character name, and then they share their desert superheroes with the other students.

Cactus Queen : Minerva Hoyt establishes Joshua Tree National Park

by Lori Alexander

What if you knew a place that was filled with thorny, spiny beauty and dainty wildflowers, but all other people saw was a wasteland? In the early 1900s that’s how people thought of the Mohave desert. But Minerva Hoyt saw the desert as a habitat worth saving, and she went all the way to Washington to let the Park Service know.

 

 

Classroom activity: Have you ever noticed the waxy coating on a cactus? What is it for? To help students understand, try this activity. Gather your materials: two sheets of paper towels, wax paper sheet a bit bigger than a paper towel sheet, and a cookie sheet. Wet the paper towels so they are slightly damp. Roll one paper towel and use a paper clip to hold it. Lay it on the cookie sheet. Lay the other paper towel on top of the wax paper, roll it, and secure it with a paper clip. Lay it on the cookie sheet. Leave the sheet in a dry place for a day and then check i. How damp are the towels now? Which one is wetter? The one wrapped in wax paper keeps the towel damp, trapping in the water just like the waxy layer on a cactus does.

A Walk in the Desert (Biomes of North America)

by Rebecca L. Johnson, illustrated by Phyllis V. Saroff

A lower middle grade text, this book uses photographs, notebook-like illustrated sidebars, and an engaging text to explore various North American deserts and the ways numerous plants and animals have developed strategies to exist in these challenging conditions. It also explores the interconnected food web and provides ideas for further research.

 

 

Classroom activity: Tell students to imagine one of the creatures in this book is the main character of a story. Have them write about its day in the desert from morning until nighttime. What other creatures does I meet? What problems does it face? Encourage students to use details from the book and do further research if they’d like. When they are done, ask them to add a few pictures—either drawings or printed images of the desert. And also ask them to create an interesting title for their book. When finished, students can host an author reading and display their book to the class.
