Recycle Your Electronics Programs for Schools

recycle electrons kidsHi,
We are writing to you on behalf of Ontario Electronic Stewardship (OES) and Recycle Your Electronics.  
We hope that your school will be interested in having a Recycle Your Electronics educator visit your school to bring our program of education, interactive in-classroom games and activities to your grades four through eight classes.  
We are now booking FREE classroom visits in your area and we’d like to schedule a class at your school in the upcoming weeks. We are touring 250 schools in Ontario and we would like yours to be one of those. Last year we ran a 32 school assembly tour and a university tour to 5 different schools.
In our presentation, we’ll use videos, games and activities all geared around recycling education that dovetails with the curriculum approved education modules we’ll provide for follow up in your classroom.
Students will learn about:
  • Understanding elements and materials in everyday devices such as rare earth and precious metals.
  • The importance of end of life electronics recycling and participating in sustainability, right here in Ontario.
In addition, we’d also like to know if your school might like to participate in an Electronics Recycling Collection event. It’s a great fundraising program for schools where electronics are returned to the school by parents and families and schools receive funding based on collected materials. It’s a great way to tie in the teaching we’ll already be doing together. If you think your school might be interested in this second element of a collection event, we’ll have someone from OES get in touch with the school contact you provide and they’ll take it from there! 
Thanks once again for your interest in the program and your commitment to enhancing your students’ understanding of these critical issues, related to the science curriculum.
Here are a few videos to check out from last year.

In 2016, the Recycle Your Electronics tour will once again be travelling throughout the province, working with eco clubs and schools, science teachers, and educators looking to make a difference in their schools and communities.

If you’d like the Recycle Your Electronics tour to visit your school in 2016 without charge, let us know by filling out an application form found here.

If the environment were able to send us a text or give us a call from the future, it would ask us for our help. How will we answer?

Recycle Your Electronics: Classroom Activities to Teach Stewardship

Curriculum Connection: Grade 9 Applied and Academic — Physics, Technology

We all love our electronics. We never go anywhere without them and we want to keep up with the latest and greatest tech toys.

Did you know electronics contain gold and other precious metals? They are also made with some hazardous materials, and contain recyclables like glass, plastic, and metal. That’s why it’s a lot more efficient to recycle these materials safely than to dig them from the ground or to remake them.

But, what do we do with our out-of-use electronics? What is the responsible choice?

Our job at is to make sure that there is a safe, environmentally responsible way to reuse or recycle electronics. is operated by Ontario Electronic Stewardship (OES), and is a not-for-profit organization funded and governed by the electronics industry producers. offers a convenient and secure way for Ontario residents and businesses to recycle electronics free of charge. We believe that we have a shared responsibility to take care of electronics here in the province we call home;,using high environmental and health and safety standards. So we divert these items from landfill, using local service providers who adhere to strict regulations and standards, including techniques to ensure sensitive data, such as your personal information and photographs, are destroyed in the recycling process.

That’s where you come in. Learn how to reuse or recycle your electronics. Take action by collecting electronics at home, in your school and in your community.

Help divert electronic waste from landfill and protect our environment. Remember the three Rs: reduce, reuse, and recycle. Use your electronics as long as possible.

When you have to replace your electronics, take the old or unwanted item(s) free of charge to one of hundreds of
approved collection depots, sites or events. Go to to find out where and how.

On the following pages, you’ll find some activities to do with your class, to help teach about electronics recycling.

Taking care now will mean a greener tomorrow for us all.

The Urban Water System

water challenge


Turn on the tap and out comes water. Unused water goes down the drain. In this activity, students gain an understanding of where the water comes from, how it gets into the tap, and where it goes when it flows down the drain.

Students will need to be able to access dictionaries or books that explain the New Words in order to gain a more complete understanding of a typical urban water system, or cycle, as we call it here.

Three steps occur in the drinking water treatment plant. These include chlorination, flocculation, and sedimentation/filtration. The chlorination step is necessary to kill any bacteria in the water, particularly those responsible for cholera and typhoid fever. In the next step, chemical coagulants, such as polyhydroxyaluminumchloride, are added to the water. These chemicals cause dirt particles to “stick together” as larger, heavier “floc particles” that fall to the bottom of settling tanks where they can be removed. The very fine particles that remain after this step are removed from the water by sand filtration. This step is very similar to Activity 4 Purifying Water included in the Grade 7 Unit on Pure Substances and Mixtures. The filters have light, black pebbles on top, with sand and gravel arranged in layers, with the largest particle sizes on top. As the water passes through, fine particles are removed. The filtered water is then treated with sulphur dioxide to remove all but a trace of chlorine. In some urban water systems, fluoride is added for the benefit of your teeth.

The sewage treatment plant carries out a number of processes to remove waste from the water before returning it to the environment. In this plant, raw sewage is passed through coarse screens to remove large material. Then a settling tank is used to precipitate most of the inorganic matter from the water. Any remaining organic matter is then removed through additional settling and aeration tanks. In the aeration process, micro-organisms, aided by air pumped through the water in the tanks, oxidize the organic matter. The sludge left after these processes is precipitated in a final settling tank and the water is chlorinated and returned to lakes or streams. The waste sludge from all the steps is collected in digesters where anaerobic bacteria further oxidize it. The gas given off in this process is either burned off or used to produce heat. The non-organic sludge that remains is piped away from the plant for disposal.
