(Note: You may want to have an overhead transparency or other classroom copy of the seven steps already prepared and available for reference at this point see the 7 Steps of Integrated Waste Management Transparency.) In order, the seven steps are: reduce, reuse, recycle, compost, incineration with energy as a result, landfills and incineration with no energy. The key is to have barely any waste left when reaching the last step.Ī total of seven steps comprise integrated waste management. These are the first four steps in "integrated waste management." This means that you try to reduce the amount of garbage by the first step (reduce) and with what garbage is left, you venture onto the next step (recycle), and so on, until the garbage or waste is all gone. The most environmentally friendly ways to dispose of trash are to reduce, reuse, recycle and compost. Write student suggestions on the classroom board.) Expect students to mention landfills and recycling centers, and maybe dumps, trash cans, compost bins, etc. What are some different ways to dispose of trash? (Brainstorm a list of answers as a class. Did you know that people and industry produced more than 292 million tons of waste in 2018, which is more than four pounds of trash per person per day? Wow, that's a lot of garbage! International Technology and Engineering Educators Association - Technology Thus technology use varies from region to region and over time. Relationships can be classified as causal or correlational, and correlation does not necessarily imply causation.Īlignment agreement: Thanks for your feedback! The uses of technologies and any limitations on their use are driven by individual or societal needs, desires, and values by the findings of scientific research and by differences in such factors as climate, natural resources, and economic conditions.

But changes to Earth's environments can have different impacts (negative and positive) for different living things. Human activities have significantly altered the biosphere, sometimes damaging or destroying natural habitats and causing the extinction of other species. But individuals and communities are doing things to help protect Earth's resources and environments.Ī system can be described in terms of its components and their interactions.Īlignment agreement: Thanks for your feedback! Science findings are limited to questions that can be answered with empirical evidence.Īpply scientific principles to design a method for monitoring and minimizing a human impact on the environment.Īpply scientific principles to design an object, tool, process or system. Human activities in agriculture, industry, and everyday life have had major effects on the land, vegetation, streams, ocean, air, and even outer space. Obtain and combine information from books and/or other reliable media to explain phenomena or solutions to a design problem.Īlignment agreement: Thanks for your feedback! This lesson focuses on the following Three Dimensional Learning aspects of NGSS: Obtain and combine information about ways individual communities use science ideas to protect the Earth's resources and environment.Ĭlick to view other curriculum aligned to this Performance Expectation

Describe the different steps involved in integrated waste management.Explain 3RC (reduce, reuse, recycle, compost).Explain some of the major problems that waste disposal causes.Explain different methods of waste disposal.Then have students explore the third "R", recycling, by conducting the activity Test & Improve: Making Tall & Strong Recycled Towers.Īfter this lesson, students should be able to: Have students explore how engineers work with composting in landfills by conducting the associated activity Composting – Nature's Disappearing Act.

Engineers investigate ways to accelerate the decomposition process, develop industrial systems that burn trash for energy at power plants, and design innovative landfills that are more economical and reduce pollution. Chemical engineers develop environmentally friendly, recyclable materials. They use smaller amounts of materials to package products as discussed in the relevant activity It's all In the Package, and use recyclable and reusable materials when possible. This engineering curriculum aligns to Next Generation Science Standards ( NGSS).Įngineers are involved in all steps of integrated-waste management. Through an associated activity, they observe biodegradation in a model landfill (composting). They look at the effects of packaging decisions (reducing) and learn about engineering advancements in packaging materials and solid waste management.

Students expand their understanding of solid waste management to include the idea of 3RC: reduce, reuse, recycle and compost.
