In this lesson, students expand their understanding of solid waste management to include the idea of 3RC (reduce, reuse, recycle and compost). They will look at the effects of packaging decisions (reducing) and learn about engineering advancements in packaging materials and solid waste management. Also, they will observe biodegradation in a model landfill (composting).
In this brochure, the European Aluminium Association (EAA) evaluates the need for vehicle lightweighting to reduce CO2 emissions. Since the 70's aluminum has been used for some car components (radiators, cylinder heads, and bumper beams), but now has grown to the average amount of 140 kg per car produced in Europe. Aluminum castings, extrusions, forgings and sheets can now be found nearly everywhere, including in car bodies, closures, chassis, suspensions and wheels. This resource explains why, now more than ever, reducing vehicle mass is necessary and how aluminum can be used to further improve the sustainability and the safety of future generations of cars.
This report by The Aluminum Association reviews the North American use of aluminum over the past 20 years in order to improve industry emissions, efficiency, recycling, and to address the challenges ahead in regards of sustainability. Challenges faced with sustainability include technological progress, energy and resource use, waste minimization and elimination, business operations, and product end-of-life ("design for recycling" and recycling incentives).
Try this variation on the Art experience âdecorate binoculars.â It uses small plastic bottles instead of cardboard tubes to make binoculars. They are sturdy and provide a great reinforcement to recycling.
Students are challenged to design a method for separating steel from aluminum based on magnetic properties as is frequently done in recycling operations. To complicate the challenge, the magnet used to separate the steel must be able to be switched off to allow for the recollection of the steel. Students must ultimately design, test, and present an effective electromagnet.
Students investigate decomposers and the role of decomposers in maintaining the flow of nutrients in an environment. Students also learn how engineers use decomposers to help clean up wastes in a process known as bioremediation. This lesson concludes a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.
Without the work of decomposers, living organisms would eventually use up all the raw materials in the environment, and dead organisms and wastes would pile up. This video segment from Interactive NOVA: "Earth" describes the role of decomposers as the earth's great recyclers.

Students brainstorm ideas for board game formats. Then student teams design, create and test games in which players must think of alternative uses (recycling) for used products.
A sequence of teaching units and activities including 3 associated STEAM lessons with the aim of acquiring a series of specific skills about waste management (in particular about Waste source separation and recycling).This is the second Digital Project of a set of 6 facing specific challenges about waste management for primary and secondary education
How does infrastructure meet our needs? What happens when we are cut off from that supporting infrastructure? As a class, students brainstorm, identify and explore the pathways where their food, water and energy originate, and where wastewater and solid waste go. After creating a diagram that maps a neighborhood's inputs and waste outputs, closed and open system concepts are introduced by imagining the neighborhood enclosed in a giant dome, cut off from its infrastructure systems. Students consider the implications and the importance of sustainable resource and waste management. They learn that resources are interdependent and that recycling wastes into resources is key to sustain a closed system.
Students listen to the book Earth Day Hooray! and learn how incentives change people's behavior. The students learn how characters in the book collect cans to sell to the recycling center and use the money they receive to buy flowers to plant in the park. In a classroom discussion of the story, students track the number of cans brought to school each day. Students evaluate scenarios to determine what behavior is being encouraged or discouraged and to identify whether the incentives are rewards or penalties.
Learn about environmental chemistry through engaging, bitesize animated videos. The videos are organised into chapters including: the earth, the air, water, rocks, metals and their reactivity, global warming, carbon chemistry, fuels and recycling.
In this lesson students will explore the concepts behind the Reduce, Reuse, Recycle slogan through theater.
These units, and the supporting resources of Global Words, aim to build the essential knowledge, skills and values young people need to participate actively, critically and creatively as global citizens. This curriculum integrates the teaching and learning of English, across strands of language, literature and literacy, with Global Citizenship Education, using explicit and exploratory teaching and learning activities. The four units use a range of text and text-types to address the themes of Sustainability, Refugees and migration, Neighbours, Asia/Pacific, and Indigenous peoples, with a focus on literacy with Geography and Human Society and its Environs curricula. All units of work include an overview, description of focus, four teaching and learning activities, and links to the curriculum content, strands, outcomes and indicators.
The Great Pacific Garbage Patch (GPGP) is an intriguing and publicized environmental problem. This swirling soup of trash up to 10 meters deep and just below the water surface is composed mainly of non-degradable plastics. These plastic materials trap aquatic life and poison them by physical blockage or as carriers of toxic pollutants. The problem relates to materials science and the advent of plastics in modern life, an example of the unintended consequences of technology. Through exploring this complex issue, students gain insight into aspects of chemistry, oceanography, fluids, environmental science, life science and even international policy. As part of the GIS unit, the topic is a source of content for students to create interesting maps communicating something that they will likely begin to care about as they learn more.
Just like manure, compost can improve your garden soil and make your vegetables or flowers grow stronger and healthier. Hereâs how you and your family can make some compost.
Students learn about the human water cycle, or how humans impact the water cycle by settling down in civilizations. Specifically, they learn how people obtain, use and dispose of water. Students also learn about shortages of treated, clean and safe water and learn about ways that engineers address this issue through water conservation and graywater recycling.
Students explore the concept of "reducing" solid waste and how it relates to product packaging and engineering advancements in packaging materials. They read about and evaluate the highly publicized packaging decisions of two major U.S. corporations. Then they evaluate different ways to package items in order to minimize the environmental impact, while considering issues such as cost, availability, product attractiveness, etc. In addition, students explore "hydropulping" and consider its use as a recycling process.
In the Web-based game Kure Waste Chase, students take on the part of an Ocean Adventures expedition member volunteering for the U.S. Fish and Wildlife Service and explore various habitats (beach, water surface and underwater) to collect as much harmful marine debris as possible in a limited amount of time. Use the tips and handouts below to turn the Kure Waste Chase game into a structured learning activity for your students.
