Grade 12 Sustainability Students Making the World a Better Place

Jessamyn Polson English and Humanities, Environmental Stewardship

 

Sustainability is all about living comfortably in our world while using resources responsibly so that future generations can do the same. Unfortunately, our world isn’t always a sustainable place—but our Grade 12 Living in a Sustainable World students tackled the challenge with creative workshops covering urban biodiversity, native species, and ways to protect local ecosystems.

Without further ado, let’s dig into the workshops!

Seekers

By J.P.

This workshop explored biodiversity in the city. “Biodiversity” might sound complex, but it simply refers to the wide variety of species that share an ecosystem—including urban spaces! To prove this, J.P. introduced students to the Seek app by iNaturalist, which helps users identify plants and animals using their phone cameras. Participants then headed to the park across the street with a scavenger hunt checklist, finding up to 10 different species—despite the winter weather!

Daybreak

By S.R.

S.R. introduced students to Daybreak, a unique, collaborative board game about sustainability. Unlike competitive games, this one challenged players to work together to meet the needs of their assigned countries while staying carbon-neutral. The workshop’s goals were to introduce students to sustainability-focused games and highlight both the obstacles and innovative solutions in creating a greener world.

City Safari

By F.A-L.

F.A-L. led a workshop on how species in the city are interconnected, focusing on the relationship between rats—a species subsidized by humans—and their predators, hawks. The inspiration? A red-tailed hawk that frequently perches on a tree across the street! Through an engaging presentation, F.A-L. demonstrated how every species plays a role in the urban ecosystem and emphasized the importance of respecting and protecting our shared environment.

Seed Dumplings

By M.R.

M.R. focused on biodiversity by teaching participants about Ontario wildflowers and how to make seed dumplings—small, biodegradable balls containing native plant seeds. These can be scattered in garden plots around the city to promote local plant growth. The workshop highlighted how even small, simple actions—like planting native species—can have a positive environmental impact.

Bruce’s Clothing Swap

By B.K.

B.K. tackled textile waste by organizing a school-wide clothing swap. Students brought in unwanted clothes and traded them for new-to-them items-for free! B.K. who is interested in fashion, shared with students how clothing waste contributes to landfills and environmental problems, and encouraged students to think about sustainable fashion choices. The event was such a success that students are already asking for it to become an annual tradition!

Gourmet Today and Tomorrow

By R. T., L. B., and J. I.

This workshop combined cooking skills, food insecurity awareness, and waste reduction. Students gathered in the Orange Room, where J.I. talked about how learning how to cook can help reduce food waste. Then participants split into groups to make pancakes. While pancakes cooked, R. led a discussion on food insecurity, a growing problem in Toronto, and talked about how cooking skills can help people eat more nutritiously and affordably. L. then explained how to properly recycle and dispose of food waste. The workshop highlighted both the social and environmental aspects of sustainability—all while making (and enjoying) a delicious snack!

City Chicks

By E.R. and M.T.

E.R. and M.T. led a hands-on workshop to help prevent bird-window collisions—a major cause of bird deaths in urban areas. Students made paper bird cutouts to stick on windows, a simple but effective way to alert birds and keep them from flying into glass. E.R. focused on the role birds play in urban ecosystems, while M.T. emphasized practical ways to protect them. The goal is to fill the windows with colorful bird silhouettes—a creative and impactful step toward making the city safer for wildlife.

Our World Today and Tomorrow was an assembly that was both fun and meaningful, offering students a chance to learn about sustainability through hands-on activities. 

On behalf of the entire Living in a Sustainable World class, thank you to everyone who participated and supported our workshops—it made all our planning and hard work worthwhile!

Sustainable Suggestions from the Grade 12s!

  • Pay attention to the plants and animals in the city. It’s cool, and it helps shift our mindset about what a city is. A city is an ecosystem!
  • Participate in citizen science! Using Seek by inaturalist is a cool way to contribute to an open database of information on plants and animals around you. Scientists use the data for their studies too so you are helping them out!
  • Plant native plants! Especially Milkweed, the Monarchs love Milkweed and Monarchs are very cool and weird.
  • Are you building things in the city, or renovating? Use bird-safe glass to protect our migratory birds!
  • Keep your eye out for our city’s population of Peregrine Falcons and Red Tailed Hawks because they are cool! But birder beware – you may see a pigeon disembowlment. 
  • Cooking cuts food waste, and it’s fun! 
  • Advocate for a national food insecurity policy. Food banks can’t keep up with the need right now and a lot of people are suffering.
  • Did you know we can’t recycle black plastic in the city? But did you know that now we can recycle reusable coffee cups and lids?! Use Waste Wizard to make sure you are recycling everything you can!
  • Play sustainable games like Daybreak, and Pandemic, and Rain World – they are fun and creative and hopeful!

Level Up! Trades Fair

As a first for our school, six senior senior students interested in pursuing trades after high school attended the Level Up! Trades Fair. The Mississauga International Centre had 144 different trade vendors spread across Hall 2, ready and eager to talk about their trades. Students had a two hour slot to walk around and explore a multitude of trades and vendors. Most of the vendors had fun, hands-on opportunities for students to engage with. From learning how to lay bricks and patch drywall to welding pipes, braiding hair and applying make-up, there was no shortage of tactile experiences for students to explore. There was even a mini helicopter and full sized TTC buses to explore. Whichever trade a student is interested in, the Trades Fair had something for everyone. This is a trip worth returning to next year with even more students.

Building a Roman style Aqueduct

Megan Steciw Experiential Learning, Science and Math

In Middle School, the students collaborated to build a wetland and replica Roman style aqueduct. One student explained, “With hard work and dedication, we made something remarkable.” The students planned, constructed and adjusted the designs in order to model their cross-curricular learning between science and social studies. Together, we have been investigating the features of wetlands including the biodiversity that maintains the cycles within these diverse habitats. The Toronto Wildlife Centre most recently visited the Middle School, delivering the program Kids Go Wild and providing insight on how to protect wildlife in urban spaces including decorating windows and keeping cats indoors.

The students continue to investigate natural wild spaces in the city for inspiration including Ramsden Park. One wetland, explains a student, is more realistic with dirt, seeds, rocks and the sponges represent how the wetland acts as the absorbent for pollutants from the atmosphere. The other wetland is a model of a wetland with plasticine and plastic to represent human impacts on the environment.

For the aqueduct, the students used cardboard, hot glue, and wax paper to construct a functioning system that channels water. A student described their tremendous efforts and how they had “fun” participating in the build. The opportunity encouraged them to maintain their motivation and inspired their individual creativity.

Exploring Ecosystems through Experiential Learning

Jessamyn Polson Experiential Learning, Science and Math

It is my privilege to be teaching a grade 12 geography class called Living in a Sustainable World (CGR4E/M) this semester, and we have had a busy month! Here is a recap of what and how we have been learning about Species and Spaces, and exploring the challenges and wonders of ecosystems, conservation, and the impact humans have on the environment.

We started by building water filters to explore the UN’s Sustainable Development Goal 6: Clean Water and Sanitation. Students learned about an ancient water purification system from the Nile Region called a Kilga, built gravity based water filtration systems, and connected their learning to the Elevated Wetlands Sculptures by Noah Harding that contribute to the restoration of the Don River ecosystem. By testing their designs, they gained a firsthand look at the challenges of accessing clean water and the innovative solutions needed to ensure water quality for all.

Next, students explored the biotic and abiotic factors that influence ecosystems by hatching brine shrimp. They monitored salinity, water clarity, hatching rates, and temperature, collecting valuable data to understand how environmental conditions affect living organisms. We then moved on to creating self-sustaining terrariums. Students built mini ecosystems with drainage layers, moss, plants, and small invertebrates like pill bugs and springtails. These terrariums provided a tangible way to observe the balance and interconnectedness required to maintain healthy environments.

A highlight of the unit has been a visit from a Scientist at Large, from the Ministry of the Environment and Climate Change Canada. Wildlife biologist Jennifer Thompson visited us in person and spoke about species at risk and the importance of indicator and umbrella species in monitoring ecosystem health.

To bring all these concepts together, our students created a collaborative map highlighting endangered species and ecosystem conservation efforts, emphasizing Indigenous stewardship. This project not only taught students about biodiversity and conservation but also highlighted the people who are on the frontlines of ecosystem defense and conservation globally: Indigenous people.

There were hiccups and challenges along the way (RIP our first brine shrimp hatchlings) but through these activities we collectively developed critical thinking and problem-solving skills while learning to become responsible stewards of our planet.

Student Newscast – Politics in Action

Brandon Stewart Community, English and Humanities, Experiential Learning No Comments

Last semester, the students of the Grade 11 Politics in Action class at YMCA Academy took on a new role as journalists and news anchors. They headed a project in which they produce an audio Newscast every two weeks in an effort to inform and entertain their fellow students. Stories ranged from upcoming school events, to the weather, to interviews with members of the community.

From brainstorming the content, conducting research, drafting the scripts, recording the segments, and editing the audio files, the grade 11 Politics in Action class put in the work to bring upcoming events, sports, weather, and news to their peers.

One of the installments of Student Newscast included an interview with the then interim Head of School, Steve Saunders. Student Newsroom connected classes to the school, and the school to the world of political change around them.

The last installment of Student Newsroom included a feature piece on National Day for Truth and Reconciliation, and the school’s Orange Shirt Day assembly.
