Spooky trees: A Hallowe'en Symbol?

 by Marie Powell

When we think of Halloween icons, we often think of screeching black cats, howling ghosts, and withered witches with tall black hats. But there’s nothing as common -- or as spooky -- this time of year as the bare branches of a tree against the grey sky, when the wind howls at the end of the day.

 

Stories of tree spirits and the magical properties of each species abound on the Internet and in books. Stories of spirits and magic were part of the beginnings of science, as people began trying to understand the natural world. Yew trees (Taxus baccata) are often mentioned in folklore and magical contexts. It’s a favourite material for everything from wiccan wands to medieval bows, but the leaves, bark, and seeds contain taxine, which can cause heart problems [Isabella, 2020].

The yew tree is also a symbol for protection and longevity. One old folk tale stars a real tree known as the oldest Yew tree in Wales, the Llangernyw Yew near Conwy, North Wales. It’s estimated to be nearly 5,000 years old, and has a cleft trunk (see photo) that some say is a portal to the world of the dead. [Atlas Obscura, 2020]. 

The tree is associated with a spirit called Angelystor. On Halloween, this spirit enters the north door of the village church to announce the names of villagers who will die during the upcoming year—and from all reports, it’s not a good idea to test this spirit. One tailor who scoffed heard his own name announced and was dead within the year. [Owen, 2006].

In a lighter vein, the yew tree is also among the trees recommended as a habitat for certain types of birds and animals [BBC]. Trees are considered sacred in many cultures, and have even been graced with magical properties in some. The birch tree, for example, has been connected to creativity and fertility, possibly because it’s one of the first trees to grow back after a forest fire. The oak is considered a symbol of endurance and power. [Wigington, 2019].

Each type and variety of tree has a particular nature. According to The Woodland Trust, noticing a combination of features is the best way to learn about the nature and identity of a tree. Trees differ in several basic elements: the shape, size, and colour of leaves or needles, the texture of its bark, or the types of buds, fruits, and flowers. The overall shape or silhouette of the tree provides a clue. Even the location where the tree can be found helps identify its nature, since some trees prefer to grow near water, while others prefer woodlands or scrubland. [The Wooodlands Trust, ND]

Trees play a role in the lives of many animal and bird species, as a source of food, nesting sites, and roosting spaces. A natural landscape that includes trees is recommended for optimum health. [BBC] Anyone who has ever felt the calming and de-stressing effect of a great old tree could agree that this in itself is potentially magical [Whitehurst, 2020]. Whether or not trees have spirits, they certainly can lift our spirits—hopefully in time for this Covid Hallowe’en!

Don't Steal My Candy!

 Video by Joan Marie Galat

Are you thinking of ways to protect your candy after Hallowe'en, later this month? Here is a STEM activity you might consider trying at home. Check out this video by Sci/Why author Joan Marie Galat, on how to use PHYSICS to set up a surprise for sneaky candy thieves.

Science Literacy course for free

 by Paula Johanson

There's so much science being mentioned in the news and social media. But how are we supposed to know the difference between a sensational story and hard facts? 

A new online course in Science Literacy offered by the University of Alberta is ready to help learners spot sound science—an increasingly relevant skill in today’s world of social media. This course is available at no charge. “The purpose of this course is to teach people about the process of science and how it is used to acquire knowledge,” said course host Claire Scavuzzo, researcher in the Department of Psychology.

Students will have the opportunity to learn how wisdom is gained and practiced by Canadian First Nations, Indigenous, and Metis peoples, compared to the westernized process of science. They will also learn how to think critically about scientific claims from a variety of sources.

This online course would be useful for adults or teenage learners, or for a family to study together. There are no prerequisites, and a variety of guest lecturers. The course can be completed at the learner’s own pace—roughly five weeks with five to seven hours per week of study. The five modules of the course are presented with practice quizzes, reflective quizzes, and interactive learning objects that are all available for free. It would be great for anyone who wants to learn about science. Click on this link to read a detailed article about the course, and click on this link to register for free. It's even possible to upgrade and get a certificate of completion!

Learning About Gardening

 by Margriet Ruurs

There’s nothing like a pandemic to make people want to be more self-sufficient.
First, everyone stocked up on toilet paper and flour. You never knew which shelves would be empty the next time you ventured into a supermarket. It even became difficult to buy new laying hens since, suddenly, everyone wanted chickens. And everyone, it seems, wanted to grow their own food to be on the safe side.

Once school was discontinued, my ten year old grandson Nico watched more movies than normal. One of them was a fabulous documentary called Biggest Little Farm which you can find at this link. The film follows ten years of a young couple who buy an acreage and, never having farmed before, turn dead soil into a gorgeous lush farm. The film is inspiring on so many levels, and not just to adults.

Three days after viewing it, Nico came to get me. “I want to run my own farm,” he announced, asking if he could use a flat piece of land on our 5 acres. The piece of our acreage which he selected was outside our deer fencing and thus not a good choice. But we soon found another, better suited piece of level land which is protected from the many deer that roam our island. He staked it off and, after promising to do all the weeding and watering, it was his.

His dad happened to own an old-fashioned plow so he turned the grass. Nico spent the next week on his knees, pulling grass and weeds from clumps of clay.

He designed a garden plan with beds and paths.
Friends donated berries, seeds and seedlings. We also made a trip to a local organic farm for some seedlings which he nurtured in a bay window until the weather turned warm enough for planting.

By early May, in the Pacific Northwest, it was time to plant. Nico chose his own crops: corn, peas, potatoes, squash and more.

He planted, pulled more weeds and watered. He also had to put up a small fence to keep rabbits from helping themselves to his hard earned veggies. All of the weeds he pulled, sometimes helped by his younger brother, were donated to the chickens who munched happily and turned the greens into eggs.

In turn, we put egg shells, coffee grinds and vegetable waste into our composter and mulch compost into the soil. Growing veggies is a never ending circle.

By June, the potato greens were up and the peas were climbing the bamboo stalks. In July the corn grew over his head and the tomato plants had yellow flowers.

By early August Nico was able to harvest the first huge zucchini and share it with his family for dinner.

Hopefully 2021 will be a better year for the world, without a pandemic. But the science of producing your own food is here to stay. And hopefully Nico will be inspired enough to keep growing his own vegetables and munch on snacks that he nurtured himself, from seeds to fruits.

 

Here are names of two books to consult if you want to start your own garden:

POST NUMBER 500!! Pros and Cons of Studying Elsewhere

Here's our latest post, and it's a real milestone. Welcome to the FIVE HUNDREDTH post on our science writing blog! This one's a trip down memory lane.

Pros and Cons of Studying Elsewhere

by Raymond Nakamura

Ecology is a science in which place makes a big difference to what you study. During the pandemic, travel is not advised, so I thought I'd share some memories of when I went to Japan to study, as a kind of thought experiment.

As an undergraduate, I studied zoology as my specialist subject and Japanese language as my minor. I found out from studying French in high school, that if you don't use it, you lose it. One of my Japanese professors told me studying language would be boring, so I should learn it while studying something I was interested in. I figured that since Japan was an archipelago, it would be a good place to study marine biology. Never mind that my lowest grades were in Japanese language and marine biology.

This was back before the Internet, so finding Japanese professors took a bit of effort. I had to go through the library and scour the papercut delivering pages of scientific journals. Eventually, Professor Taiji Kikuchi at the Amakusa Marine Biological Laboratory of Kyushu University accepted me.

So I left my family home in the city of Toronto and packed up to live on my own in a little village in southern Japan. I ended up studying the population ecology of a stalked barnacle, Capitulum mitella. 

This meant marking more than a hundred individuals that I would measure during every low tide cycle. 

During the winter, that meant going out in the middle of the night.

 

Sometimes I went further afield to help with studies on endangered species...

...or surveys of less studied habitats, such as Zamami Island in Okinawa.

Sometimes I came across different creatures while doing research or during the course of my travels.

 

I also had the opportunity to find life in my own home. 

 

I found that studying disagreeable things is a way to cope with their existence. 

 

Others were more occasional visitors, such as land crabs, mice, spiders, and centipedes.

 

I realized I preferred my wildlife outdoors.

That was all many tide cycles ago. I now live in Vancouver, where I am a lapsed biologist, more interested in sharing discoveries by other people than working out my own. I practise Japanese on an app called Duolingo. And when the moon is full, I just think, "Isn't that pretty," instead of, “Gosh, these rocks are cold."  

Anatomy for education

 by Paula Johanson

How are children and youths to learn about bodies for health and sex education? This topic is a matter of careful thought for many parents. And there are resources to help families with learning the science of anatomy for health and sex education.

Some of these resources are formal and written about the science of how this knowledge helps people. The United Nations World Health Organization has an e-book on International technical guidance on sexuality education, available for free download. Click on this link to find their page with links to this free e-book in English, French, Spanish, Japanese, and Russian, and also a link to another page with several more free articles to download in English.

For people needing something more oriented to family learning, there's a whole page of resources recommended by doctors on body knowledge and more available at this link from Planned Parenthood. This list includes recommended books for parents to read on their own and books they can share with their children.

Some teenagers and parents find the website Scarleteen to be useful, with articles on bodies, health, gender, relationships, and more. Scarleteen has been online for over twenty years. While it's not a place for doing science, it's a place for learning. It also has places to ask questions, including a message board and live chat.

Among the newest resources now available is We Are Beautiful, with a website at this link. The organisers of this website are concerned about a lack of educational material that shows the diversity of our bodies. As they note, some people worry that their bodies are ugly. This website has images (in green or purple) of body parts based on adults of many ages and shapes, to show the variety of shape that is normal. These images are also free downloads for a 3D printer.

Even adults who think they know all about their bodies can find things to learn from these books and websites, to improve their knowledge and health.
