A Green-Powered Canada

Completed

Description

To start off, we learned about the differences between non-renewable and renewable energy sources and some examples of each. For this challenge, we then focused on ways to use renewable energy from water. Using a Canadian Reader article about tidal energy, a classroom text about Dams and two Water Brothers episodes related to these, we considered the advantages and disadvantages of hydro power and tidal power. In the end, the class also took a vote about which source they thought had the least environmental impact.

Buckle Up

Completed

Description

We started with the text "The Way to School" which helped us explore some very interesting ways that children might travel to school around the world. We noticed that most of these methods did not involve using energy from the Earth but rather energy from their bodies or from other animals. We then thought about how we might travel to school without using Earth's energy sources as well. We made some posters that we posted at the 3 main entry doors to the school to encourage students to walk, scooter or bike to school, especially now that the weather is getting better. Mrs. Mounsey from Kindergarten came by to thank us for the posters we put at the kindergarten entry doors. She said the next day, several students rode their scooters to school!

Community Connections

Completed

Description

We participated in the Great Gulp with Eco Schools Canada. The Great Gulp is an opportunity for your class or school to all say no to one-time use plastic by taking a collective gulp of water from resuable water bottles. As a class we did some learning in advance not only about our freshwater resources but also about plastic waste. We watched a Water Brothers episode called "Bottlegate" and read a Canadian Reader article about Nestle and the water they use for their bottled water from the Guelph region in Ontario. Students used these resources as well as some further information from Eco School Canada to create a set of slides for the school to help students learn why we were holding the event. The entire school met outside on March 31st for our Great Gulp!

Do You Really Need It?

Completed

Description

As a class, we brainstormed every day things we use that require energy. Then we discussed whether they are needs or wants. (A lot of things we want feel like we really need them!) Students completed the CEDC worksheet with the activities that were most relevant for them. Everyone then selected something they would give up for a day on the weekend. We wrote letters to parents about what we would be giving up and what we would do instead. Most students chose the TV, a tablet or a phone. Students reflected on how it went for them. Some expressed that they enjoyed their alternate activities and would do it again but it was really hard to give up some of the energy using things they love!

Game Time!

Completed

Description

We read an article about food waste in Canada. Then we watched a Water Brothers video about the water usage that goes into making our food. Students also explored the links/resources provided on the CEDC website for this challenge. These sources were used to create a series of questions for a Kahoot game. Some students helped to write the questions that were used. Everyone had a BLAST playing the game and demonstrated that they had done some great learning about food waste in Canada.

Get Growing

Completed

Description

Learning about plants is a big topic in Grade 3 so we have been exploring their importance throughout the year through a variety of texts and activities. In the fall, we had a special workshop (in person but outside) with the Toronto Regional Conservation Authority. We learned about a special "Meadow Way" project that they are doing in part of the long hydro corridor that runs through our city. Part of that corridor is immediately beside our school. In early February, we planted two types of Indigenous plants in our classroom - Wild Bergamot and Black Eyed Susan. We are growing these to support the Meadow Way project. Half will go to the project and half will stay at our school. We have been keeping journals as we watch our plants go. We had a problem with algae following the long weekend in February when we over watered them a bit before we were going to be away for four days, but about half of our plants are still doing well. We are in the process of planting some additional seeds to try to make up for the ones we lost. Our Black Eyed Susan plants are surviving better than the Wild Bergamot. We also did some additional plant experiments exploring light and temperature. The plants under the grow light are doing much better than plants near the window.

How Big Are Your Carbon Feet?

Completed

Description

We learned about carbon footprints by acting out some scenarios in the gym related to heating our homes & different transportation methods. Back in class we enjoyed the Carbon Monster and Green Ninja videos. We completed a carbon footprint survey and showed our results by colouring in rings on a foot We then came up with strategies for reducing our energy use and put those on the CEDC template. Finally we created "creatures" half Carbon Monster & half Green Ninja to share our learning on a bulletin board in the hall.

One Hour No Power

Completed

Description

We began this challenge when our school board celebrated Earth Hour. Following that, we set the goal of trying to go at least one hour no power a day until we reached our target. We continue to keep most of the lights out throughout the day or use only some of the lights in the room. The hardest part was not using our Chromebooks!

Story Time

Completed

Description

We used a school door decorating contest for Earth Day as an opportunity to create and share our story about the Planet Protectors for the school to enjoy!

Take-Home

Completed

Description

Students worked on this task at home over the March break. When we returned we spent some time calculating our combined data. We found the mode of items we kept from landfill versus items that went to landfill. It was double. Woo hoo!

The Phantom of the Classroom

Completed

Description

First we learned about Phantom Power using the CEDC resources. Next we measured how many Watts a typical school Chromebook uses when it is plugged in. We went around and surveyed each class to see how often and for how long they typically charge their devices. We found out that most classes are charging them too often and for too long and that this is using unnecessary energy. The Chromebooks only need to be charged about once and week and for about 2 hours to be fully charged. We wrote to the school about this Phantom Power issue and made some digital posters as well. We are asking classes to have a better plan for Chromebook charging to help us save energy!

Tips and Tricks

Completed

Description

As we mark World Water Day 2022, our class has been looking at ways we use & can conserve water. As part of this learning we explored water footprints. This was a nice extension of previous learning about carbon footprints. Students worked collaboratively to create infographics about the water we can save when we choose one food over another. We have posted these in the school for others to see & to our class Twitter account as well.

Video Challenge

Completed

Description

We have a simple but important call to action message - BE KIND. As a class we discussed finding a focus for the video that connected to our class learning this year. We have been exploring the theme of kindness since the first week of school. Once we chose that, students filled out a Google form to share their ideas about how we should present our message. We used this to start the planning process. Students worked on writing the script both individually and as a larger group until we had something that was one minute long and conveyed what we most wanted to say. The class was then divided into six groups. Each group worked on some kind of animation as well as a live video portion. Background images used with green screen technology were royalty free for commercial use (without credits required). We would like to thank Ms. Bulgutch and Mr. Pozin for each supplying a photo we could use as well. A group of students interested in speaking roles recorded their voices. As a final touch we listened to a number of available for use Jingles in iMovie and the class voted on the one they thought would create the best background music! In a world where you can be anything, we hope you will choose to be KIND!

Water Works

Completed

Description

We collected our Day 1 data on World Water Day. The next day we calculated our usage & used this data to set specific goals for saving water based on our individual water usage. Thursday was Day 2 and we each strived to implement our goals to use less water compared to Day 1. We were very surprised how much water we were able to save as a class based on implementing some fairly simple strategies. We've also been reading a number of texts to build our understanding of why it is so important to conserve our freshwater resources.

What’s For Lunch?

Completed

Description

At our school, we have an annual tradition of tapping maple trees in the neighbourhood to make sap. Neighbours kindly allow us to tap the trees on their property. We collect the sap and boil it in our school kitchen to make the most delicious syrup! We made a simple baked french toast in a pan using locally baked whole wheat bread, Ontario eggs, apples and milk. The only non-local ingredient was the cinnamon. Then we drizzled our "school-made" maple syrup on top. You can find our recipes both for the french toast and instructions on how to make your own syrup attached. A special thank you to Ms. Bulgutch who works so hard to provide this amazing experience with our entire school each year!

What’s Old is New Again

Completed

Description

Students made some great structures out of recycled materials. Their first project was a co-operative rainbow sculpture "Your True Colours." Each student used a piece of a discarded cardboard box to make their rainbow shape and painted it. The rainbows then had slats cut in them so that they could be pieced together. The finished sculpture was put on display in the hall. The second sculpture was made by rolling long paper tubes with parges of old magazines. Students then found an interesting discard box and began gluing the tubes to the box. They decided it looked like a porcupine! Our porcupine structure is suspended from our ceiling for all to see when they come into the classroom!
