Grade 12 Sustainability Students Making the World a Better Place

 

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!

Field Study

Have you wondered what is the quality of our water and soil in the city? The students in Environmental Science actively performed water testing at the waterfront and soil testing in the parkette beside the YMCA! The students enjoyed collecting the samples, especially the water sample from Lake Ontario. We were surprised at the results we received for the oxygen levels at the waterfront. The results were either invalid or Lake Ontario is heavily polluted since we received a reading of 0ppm. The students factored into their results that we were testing near the shoreline where human pollution collects including microplastics and boat oil. A low amount of oxygen suggests that the water ecosystem is unhealthy. The students have also been engaging in possible solutions by investigating local and global environments. The students observed that there is “too much construction” in our city.

At the lakefront, the students also investigated the levels of nitrogen, phosphorous and potassium in the soil collected from the parkette. The students can be seen in the photographs performing chemical analysis of the soil samples. “We got good results,” said an environmentalist in training! The students were fascinated by the unique opportunity to engage in a field study in their local community! One student expressed:

“We could not have picked a better day. It was not raining. It was sunny.”

As we continued our field study, we compared the disturbed location (heavy human traffic area) to an undisturbed location (limited human traffic area). What area did we choose? The Green Industries terrace! We wanted to determine how healthy the soil is where the Green Industries class is growing plants and vegetables. If nutrients are too high, nutrients can become contaminants! What were the results? The students are still actively comparing the data though, most intriguing, nitrogen was high in the disturbed environment. Nitrogen is a common ingredient in fertilizers. Another student shared:

“We learned a lot about our city and the biodiversity.”

Glimpse into the life of a Beekeeper

The weather is warming up and pollinators have begun buzzing around our neighbourhoods. The YMCA Academy had a first hand lesson in a particular pollinating species. Though solitary bees, flies, beetles, birds, and native bees make up the most significant populations of pollinators, no insect has quite the same history with human activity as the Western Honey Bee.

This spring the Academy High School students got a glimpse into the life of a beekeeper. Academy teacher and hobby beekeeper, Brandon, brought in an empty hive and beekeeping equipment to demonstrate some of the jobs of a beekeeper. No bees were brought in for the demonstration, but the hive and equipment was enough to show the basics, and excite the curiosity of student participants. The workshop began with bee behaviours and biology, the life cycle of honey bees, the different types of bees, and the roles that bees take in the colony, and about the importance of pollinators in our ecosystems.

Lighting the hive smoker, and donning a beekeeper’s veil, Brandon demonstrated a hive inspection. He explained the parts of a Langstroth Hive, and how the bees use the space within. Making connections to Biology, Green Industries, and Careers courses, the students discussed the hazards and benefits of keeping bees.

Student questions focused on the role of the queen in the colony, what swarming behaviour is for, what a bee sting feels like, and how beekeepers get their start. At the end of the workshop, Brandon invited students to taste honey directly from the comb.

Environmental Action Plan

In our Biology unit, the grade 10 students spent time learning about the environment and how long certain materials take to decompose. Once they had completed their research, we decided to spread awareness by making a fun 3D display! The students brought in items and worked together to build the display. Most students were shocked by what they had learned, and made Environmental Action Plans to spread awareness and commit to changing something about their lifestyle. Some replacement items included:

  • Reusable or recyclable coffee pods
  • “Unpaper towels”
  • Bamboo toothbrushes
  • Concentrated cleaning detergents with reusable bottles
  • Biodegradable dog poop bags
  • Steel, paper or glass straws
  • Reusable coffee mugs

  • While reflecting on what they had learned, this is what they had to say:

    “The numbers don’t surprise me but I want to help because a lot of harm can be done by these things in the amount of time that it takes for them to decompose.”
    -Jasper G-S

    “These numbers surprise me a lot! I’ll be able to make adjustments to the products that I will use after learning this. I will start to recycle more.”
    -Ryan dV-C

    “I can’t believe that Aluminum cans take between 80 and 200 years to as long as a million years. I might recycle more.”
    -Lex B

    “Some of these do surprise me because it takes so long to decompose. Some of the ones that surprise me are plastic bags that take 10-1,000 years to decompose. Another one that surprises me is Chewing gum takes 5 YEARS. Candy wrappers take 10 to 20 years. Glass bottles take a million years to decompose or they don’t decompose at all!”
    -Claire K

    “All of these numbers did surprise me because I never knew that it takes that long for things to decompose!!!! I will make adjustments to the products that I use regularly after what I have learned in order to help save our world!!!!! I would also recycle more because it is better for the environment!!!!”
    -Melia M

    “A lot of these numbers surprise me and I will start to make adjustments to the products I use by using more environmentally friendly products and after learning this I will start to recycle more”
    -Erin R

    “There were lots of things that surprised me when I was learning about how long everything would take to decompose. It takes 1000 years for a plastic toothbrush!” -Matthew S

    Worms Compost Food Waste in Middle School


    Vermicomposting began by setting up two worm bins on the Academy’s main floor, preparing a habitat for the wiggly decomposers before placing them in their new home. From here, students used the worm bins to deepen their understanding of natural and human-made systems, learn worm anatomy, graph and analyze waste management and much more! The amazing vermicomposter was the perfect tool for integrating multiple curricula at the start of the middle school’s Living Things and the Land unit.
