the butterfly whisperers....

























Every year around this time, I order my butterflies.

The butterflies arrive as tiny caterpillars with jars in which to put a little food (which comes in the package) and one caterpillar. These jars will be their homes until they go into chrysalises. Then they will be transferred to the butterfly box where we will wait for them to emerge fully-winged. We watch them in there for about a week, and then release them outside. (We get Painted Lady butterflies. They are native to this part of the world and many, many others. Monarchs do not like our northern climate, and we are not on their migratory flight paths.)

I could tell you lots more about how to raise the butterflies, but it's all in the package when you order them. I usually order mine from Boreal Science in Canada, but google "butterfly kit" and do your own search. There are lots of people who sell them these days. Similarly, there are LOTS of good materials on Teachers Pay Teachers -- just search "Painted Lady Butterflies." My favourite thing is called "My Painted Lady Observation Journal" by Smart Chick Teaching Resources. It's simple to use and flexible. In Grade One in Alberta, Canada we are not required to teach life cycles, but of course you can't not do it, when these little miracles are happening in your room each day. The real emphasis, though, is on watching living creatures grow, and on finding out that even butterflies need food, shelter, water, space, etc.

[There are scads of books -- fiction and non-fiction to support this learning and extend it into the Language Arts. I often use this moment in the school year, to review and teach the kids to read the days of the week, using The Very Hungry Caterpillar by Eric Carle. This ties into calendar work in Math, as well as some simple measurement activities. And there are more art activities than you will ever be able to do in one school year! But here is my favourite.]

Raising butterflies never gets old. I have had so many, "Drop whatever you're doing and come watch this" moments with our butterflies -- watching them go into chrysalis, and especially watching them emerge as butterflies! It is so exciting; the kids are all "in." It's one of the best things I teach all year.

The butterflies actually get used to the kids, so that by the time we release them outside, they are in no hurry to fly away. I tell the kids that they have to stay still as we unzip the butterfly pavilion and let them go. But often the butterflies will land right on the kids. By this time, the kids have become little butterfly whisperers....

I know there is more to teaching than making memories, but I don't know anything that is better!

These two butterflies went straight for the fake flowers on one of
the girls' sandals!

flying colours....

















I've got to admit it: this is one of my favourite art projects.

It borrows from Science (making observations, and learning about "living things" more generally). It uses simple materials (oil pastels and construction paper). And it introduces the art concept of mark-making.

We begin by looking at lots of macro (close-up) photos of butterfly wings. We look at all of the little scales that coat the wings and create the colours and patterns. These scales make up the "fairy dust" that comes off of the wings when you touch them; or sometimes when the insect's wings move violently. Typically I will show the kids a dozen or so photos in a slide show.

A small selection of close-up photos of butterfly wings.

























After that, I let each of the kids choose a close-up photo (printed) of a butterfly wing. All of them are different, so no two kids will be drawing the same picture. I let them choose a coloured piece of 12x18" construction paper, and show them how to draw the big shapes of their wings with white chalk. Then I show them how to "colour" in their shapes using short lines for marks, in imitation of the scales themselves. It's not quite pointillism, but it's far from just "colouring in" the shapes as well. It creates texture, and rhythm and movement.

At some point, I stop the class and show them how they can "blend" colours (without blending them) by overlapping or intermingling their pastel marks. Adding yellow to an orange area to make it lighter, or adding green to a turquoise area to give it depth and interest. (This is an Impressionist technique.)

Here's a selection of butterfly wing pastel drawings from several classes of Grade Ones.
















































children, children, what do you see?







































Sometimes a photograph is a provocation.

It can be an image that elicits a conversation. That tells a story, yes. But also, one that asks a question. That asks the viewer to respond, to bring to it what he or she knows. To synthesize existing information with new.

Showing a class a photo of something in their local environment, allows the students to show and tell you what they know. To share it with the other kids. To be the experts. To be the teachers and the storytellers.



















_______________________________________________

Years ago, I realized that I couldn’t teach very much of the Grade One Social Studies curriculum through text books or other ready-made media, because so many of the objectives are specific to the community my students live in. And there’s no text book for that. I would have to create my own resources; letting the lived experience of being in Peace River, Alberta, Canada — a very specific place, at a very specific time — be my source material. The natural and constructed environments would be the “third teacher” in my students’ lives. (After their parents and myself.) (That’s a tenet of the Reggio Emilia approach to primary education.)

So I started taking photos that could provoke conversations around the curriculum objectives.

________________________________________________


1. Local Landmarks

One fall, I went out and took pictures of local landmarks in my small town of Peace River, Alberta. Places the kids would know, like the school, the swimming pool, the gymnastics gym and the hockey arena. Places like the movie theatre, the fast food restaurants, and stores. Places they should know, like the library and the museum and the town hall. I compiled these into a slide show, and we spent about a week discussing all of the landmarks; one or two slides at a time.


A river runs through it. These photos opened up discussions about rivers, islands, hills, valleys,
 and bridges. The top photo was taken by my husband, Tom Tarpey. The other two are mine.





























































































The kids had lots to say. I added bits of information to fill in the gaps. I added context for some of the landmarks using Google Maps, to show where they were. We used the satellite view to look at our local landscape; the map view to identify streets and bridges, and the street view to “walk” down the main street of town. I asked the kids to give me directions (verbally) from one place to another. “If I am looking at the Town Hall, which way do I have to turn to go to A&W?” “If I walked across this bridge, where would I end up?” And so on.


The old train station.


















Wooden sculpture of "Twelve Foot Davis" -- a gold miner,
and the stuff of local legends.



















The Peace River town hall. Note the Town of Peace River logo on the
near end.



















I printed some of the landmark photos we had looked at on card stock, and cut them into the shapes of postcards. The kids dictated a sentence or two about the landmark on their postcard to myself or a teacher aide, and we wrote them on the reverse sides of the cards as letters to their moms and dads. Then we addressed them and mailed them. Along the way the kids practiced reciting their addresses. (Not because this is curriculum, but just because it's important for them to know.)

Middle: An artifact that lives outside the museum. It's the axle from the old paddle-wheeled
boat that used to be the main way in or out of Peace River.
Bottom: local mural of the paddle wheeler.

To extend the concept of local landmarks (because the landscape is a landmark), I taped a map of our town to a tray, and put out blue and green plasticine. I asked the kids to cover the water with blue, and the land with green. If we hadn’t run out of time, I would have added Lego blocks and centimetre cubes for the kids to make houses and restaurants and bridges, etc.


























And finally — on a slight tangent — we looked at the logo of the Town of Peace River. It is a symbol the kids come across in their movements about town, and knowing about it contributes to their visual literacy and sense of place. Signs and symbols are also a part of the Social Studies curriculum. Our logo, happily, is a simplified image of the river that runs through our town and the hills on either side of it, which form our beautiful valley. So the logo is closely connected to the landmarks in our region.

We took some time to look at a watercolour painting by once-local artist, Miriam Gair,  which depicts the same landscape as the town logo — layered hills, receding waters, the sun as the focal point — talking about what is the same between the two images, and what is different.

Then we recreated the town logo on paper plates, using plasticine. I cut out “stencils” from sturdy dessert-sized paper plates, and placed each one on top of a whole plate. We squished plasticine into the holes of the stencils, using blue and yellow mashed together to make green (which tied in with our Science work on mixing colours). Then we lifted the “stencil” plates off, and — voilà — we had created images of the town logo, and by extension the local landscape.

2. Long Ago

The history of Peace River — at least in terms of European settlement* — is a short story. Our landscapes are still dotted with the remains of the homesteaders’ cabins who first cleared and farmed the land in this area. We drive by them every time we leave town. So this seemed like a good place to start the discussion about the “long ago” past of this area.

I took a photo of a fallen-down homestead. (I have since taken more.) We looked at it and talked about its size and configuration (one room), what it was made out of (wood), and where the people would have gotten their materials. Who lived in the house? How many people? How did they keep warm? What did they eat? Where would they have gotten their food? Their clothing?



















We talked about gardens and barns and outhouses. (Oh, my!) We talked about roads and churches and schools and, eventually, stores; all of this “development” organized around the central concepts of basic human needs. (A topic which is relevant to the Social Studies, Science and the Health curricula.)

The kids drew pictures of what it might have looked like here “100 years ago.”


























































All of this became the jumping-off point for other activities about our first farmers.

what makes a city....


















I teach Grade One in a town of 6000-and-some people. The nearest city of any size is 500 km away. Most of my kids have been to the city at least once, but most likely just to the (West Edmonton) Mall. Or maybe to see family.

Our Social Studies curriculum calls for an understanding of rural and urban communities. We spent quite a bit of time looking at pictures of cities and talking about what it means that a city is "bigger" than a town, working on the general concept of more. More people, which means more houses and apartment buildings for them to live in, which means more roads for the houses to be on, which means more cars, buses and trains. And so on. More stores. More gas stations. More signs. More traffic lights. More parking lots. You  name it.

For our "Building Things" unit in Science, we learned to make pop-ups. So we used our pop-up-making skills, markers, scrap paper, and small yellow stickers (for windows) to make little three-dimensional urban landscapes.



































Then we did some writing. The kids drew cityscapes, then finished the sentence: "A city has lots of ________." (Or wrote a sentence of their own.) It seems that lots of cities have super heroes, by the way. And other people standing on the tops of high buildings. With parachutes.

(Not sure if that is in the Social Studies curriculum, strictly speaking.)


















"I saw one of my cousins at the hospital."


























the shape of growth....






















I love the branching structure of so many natural things. Trees, of course; and antlers. Coral. Rivers and blood vessels. Hands. Families.

This motif is fractal. If you zoom out, you see it repeated at a larger scale. A twig is just like a branch, which is just like a tree. If you zoom in, you see it repeated at a smaller scale. The bronchi lead to ever smaller and smaller bronchioles, which lead -- eventually -- to the tiniest of blood vessels.

It's growth as a repetition of the same form at different scales. Theme and variations.

______________________________________________






















As part of a provocation about growing things, I had a tumbleweed in my Grade One classroom. We had already turned it upside down, and shaken out the seeds; then planted some of them and watched them germinate.

Then I set the tumbleweed on top of an old overhead projector and turned the projector on. On the wall, the plant drew an elegant self-portrait; a line drawing rendered in the medium of shadow. I taped up a full-sized sheet of watercolour paper to capture these beautiful lines. I left out a few Sharpie markers, and left this set-up in place for a few days. Kids took turns tracing the shapes of the shadow branches.








































Next, I removed the drawing from the wall and taped it down to a table. I left out blue watercolour paint in several shades. I wet the whole page down with clear water, and the kids painted the blue all over, wet-into-wet.





















Finally, when the paper was dry, we painted the large branches with a brown watercolour wash.





















_______________________________________________






















At the same time, we were drawing trees. We were looking at slabs of wood, cross-sections of trees that revealed all of the annual growth rings. I showed them Bryan Nash Gill's prints made by inking tree slabs and pressing them onto paper. We learned about "heartwood" at the core of the tree, the central structure from which growth begins.

We learned that growth comes from the heart, and reaches out in every direction.

dyeing to know....


















I’m in love with teachings that cross over curriculum boundaries. This one hits objectives in Science, Social Studies, Language Arts and Art.

So.

I wanted to dye Easter eggs using natural dyes with my kids this year, but I ran out of time before Easter. I knew I needed to experiment a bit to see what works (as far as both products and processes).

So over the school break I played around in my kitchen at home, making dyes from the following substances: onion skins, red cabbage, beets, spinach, and cherry juice. I won’t go into the how-to’s because they’re on dozens of blogs you can find through Pinterest. But I will say, it takes a surprisingly long time to get colour from natural materials. Most of my eggs were in their dyes for at least 12 hours, and some 18. The onion skins were the fastest; but I never did get colour out of my beets.


























When school resumed, I took in the results of my egg-dyeing experiments, along with some raw wool I got from my local museum. I took in a hand-knitted sock (also from the museum, and also made from unprocessed wool). And I set them all up as a provocation with a few questions:

Which dye do you think made which colour? (The big surprise being that “red” cabbage, which is actually purple, dyed the eggs blue.)
What is the material in the bowl? (the raw wool)

The provocation.


















Over the course of the week, I revealed the answers to these questions, but many more were asked. We read Weaving the Rainbow by George Ella Lyon, and Charlie Needs a Cloak by Tomie de Paola. We watched videos on youtube that showed spinning and knitting. I showed them slides of my trip to Peru, during which my family visited a small llama/alpaca farm and saw traditional dyeing and weaving being done. We talked about resourcefulness, and how people (“long ago”) would have had to make their own dyes, their own wool or other fibres, and their own clothing out of what they could find or grow locally. 


















Then we tried to dye our wool in our natural dyes. The onion skin dye was effective, but nothing else was; even ones that had worked on the egg shells. But that was a good learning moment too. Not everything works the first time you try it. And there once was a world in which everything didn’t come with instructions on the package and money-back guarantees.

We wrote hypothetical letters to our great-grandparents, listing all of the steps they would need to complete if they wanted some new socks for the winter; starting with shearing a sheep and ending with knitting. We talked about how much time and effort that would take, and how precious those socks would be to you; how you would have fewer pairs of socks and how you would darn them if they got a hole in them. And we compared that whole process to our contemporary one: driving to Walmart to buy a pair of socks for a few dollars. Throwing them out when they got holes in them.

We talked about the awesome skills people would have had a few generations back; and about how their lives were harder than ours. How life has changed. We expanded our concepts of “traditional” and “modern,” as well as “natural” and “synthetic,” “transparent” and “opaque,” "paint" and "dye." We compared the vibrant colours of our times with the comparatively muted, watercolour tones of “long, long ago;” as well as the smelliness of things like natural wool and cabbage dye, compared to our scent-censored lives today. We talked about how much itchier and scratchier clothes must have been for our great-grandparents.

Next, we tried our hands at a simple weaving project.
