STEM Tuesday– Plants– In the Classroom

 

Most plants obtain their energy by converting sunlight into food, which makes them a target for hungry animals. But not all plants are defenseless. Some plants fight back, and a few even become a threat to those trying to eat them. These books explore many interesting plants and the strategies and adaptations they use to survive. They make a great starting point for nature explorations, classroom discussions, and activities!

 

Killer Carnivorous Plants (Creepy, Kooky Science)Killer Carnivorous Plants

by Nathan Aaseng 

Plants gather energy from the sun and turn it into leaves, flowers, fruit. Animals, who can’t produce their own food, eat the plants. But what happens when you turn the food chain upside down? When the plants are the hunters and animals the hunted? In this book you’ll meet sticky traps, trigger traps, and pits of death. There’s also a handy survival manual for carnivorous plants.

 

Classroom Activity – Build a Carnivorous Plant Model

How do carnivorous plants trap animals and insects? Divide students into small groups. Assign each group a type of carnivorous plant trap mechanism, such as snap traps, pitfall traps, and sticky traps. Each group should research their assigned trap and the plants that have it. Using classroom craft supplies such as paper, cardboard, string, and glue, each group should design a working model of their plant trap. When all models are completed, each group of students can share what they learned about the trap and demonstrate their model for the class.

Beware the killer plants – the leaves that sting, the jaws that trap. This book, not for the faint-of-heart, is the perfect read for kids who want to know about the bird-catching plant, vampire vines, and corpse flowers.

 

 

A Deathly Compendium of Poisonous Plants: Wicked Weeds and Sinister SeedsA Deathly Compendium of Poisonous Plants: Wicked Weeds and Sinister Seeds

by Rebecca Hirsch

For older readers, Hirsch has an engaging, conversational, almost conspiratorial, text invites the reader on an exploration of the “science, history, and true crime coverage” of fourteen poisonous plants, seeds, and fungus found around the world. Gorgeous taxonomic illustrations, photos, and “Deadly Details” sidebars help highlight some innocent and more sinister encounters with these plants.

 

Classroom Activity – Design Your Own Deadly Plant

Nature has created many deadly plants. Now, it’s your turn! Students should use their imagination to create a poisonous or carnivorous plant. Write a description of the deadly plant and include the following details:

  • Where does the plant grow?
  • How does it trap or poison prey?
  • What adaptations does the plant have?
  • What animals or humans should avoid the plant?

Students can draw a picture, create a model, or build a representation of their deadly plant creation and present it to the class.

Classroom Activity – Poisonous Plants Safety

What poisonous plants live in your community? Have students select a local poisonous plant to research, individually or in small groups. With the information they learn, students should prepare a public safety announcement to warn people about the dangers of the plant. They can make a safety poster, film a commercial, or make a PowerPoint presentation warning about the local poisonous plant. The warning should include information about where it is commonly found, how to identify the plant, symptoms that occur when one comes into contact with the poisonous plant, and first aid tips.

by Andy Warner

From trees to rice, tea to spice, plants are central to our day-to-day lives. In graphic novel-style, this book explains how plants, from corn to potatoes, shaped human history. First, a grounding in plant essentials: photosynthesis, food web, and a fun graphic table of contents. Chapters focus on wood and wheat, tea and tulips, potatoes, peppers, cotton, corn, and rice.

Classroom Activity – What If Plants Disappeared?

Plants have had an integral role in Earth’s history. Animals and humans have relied on plants for food, shelter, and more. But what if plants disappeared from Earth? What impact would it have on ecosystems, animals, and humans? Conduct a group discussion or have students write a brief essay on the significance of plants to ecosystems and human life. Have them think about what life would be like without plants.

STEM Tuesday– Plants– Book List

Rooted to the ground, plants are pretty much stuck in place. Most of them get their energy from turning sunlight into food – which makes them a target for hungry animals. But some plants fight back, and some turn the food web completely on its head. These books might inspire you to think about plants in a different light.

Rooted to the ground, plants have to find nutrition, fend off predators, and survive whatever conditions the environment throws at them. From water lily leaves that could serve as rafts to a flower that smells like a rotting corpse, meet the plants that thrive by using brilliant and bizarre adaptations.

Beware the killer plants – the leaves that sting, the jaws that trap. This book, not for the faint-of-heart, is the perfect read for kids who want to know about the bird-catching plant, vampire vines, and corpse flowers.

Plants don’t have brains, but they can sure fool animals – even humans! They have ways to defend themselves from harsh weather, being stepped on, and from being eaten. Some plants fake leaf damage and one plant plays dead to discourage predators. And some plants turn the tables and hunt insects.

Plants can’t move when conditions get tough, like little to no water, extreme cold, or high levels of ultraviolet radiation. Yet, some of the largest, oldest plants (some 3,000 to 5,000 years old) thrive in these harsh conditions with unique structures and ingenious lures for both pollinators and prey (using sticky, snap, and suction traps). Great photos and graphics, “Fun Fact” sidebars, and a STEAM Challenge to create a model of a “new plant species” help explore these extraordinary plants.

Explore forty-nine of the world’s most incredible plants, from prehistoric species (which have existed for around 300 million years) to giants (both in height and width), from spectacular leaves, flowers, seeds, and roots to some  truly unusual plants. The fascinating illustrations also depict the flora, fauna, and environments interacting with these amazing plants and provide a wonderful, global indexed map.  

What good is a dead plant? Examining dried specimens, farmers can learn about weeds and ecologists can study plant diversity and see how plant populations have changed in the past 200-plus years. Readers will learn how plants are collected and preserved, and be inspired by a kid who discovered a new species in his backyard.

GENERAL/ OVERVIEW:

An introduction to the Plant kingdom, how plants grow, leaves, and seeds. One section dives into ferns, conifers, and other nonflowering plants. A longer section highlights flowering plants, pollinators, fruits, and grasses. Filled with photos and sidebars that explain concepts such as photosynthesis.

This book begins by comparing your body to that of a plant. Where we have skeletons, plants have stems, trunks, branches. Where we have toes, plants have roots. One chapter focuses on leaves, others on flowers, pollinators, fruits, and seeds. Activities range from making fruit shakes and salad to leaf prints, seed sprouting, and finding fibers.

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!
