Ask a Question

Synopsis
  • This article examines the environmental impact of metal production, the benefits of reusing metal materials, and how much CO2 equivalent emissions can be reduced if metal recycling continues to expand.
  • Students will learn that metal production causes soil and water pollution, metal recycling can reduce negative health outcomes, and many gigatons of CO2 equivalent emissions can be sequestered if metal recycling grows by a marginal amount.
Teaching Tips

Positives

  • This article also addresses shortcomings and expenses associated with recycling metal, giving students a full spectrum of pros and cons.
  • The citations for this article are relatively recent.

Additional Prerequisites

  • The links in the References section work if you copy and paste them.
  • Students should know what greenhouse gases are and how they impact the environment.

Differentiation

  • To assess prior knowledge, the teacher can ask the class questions about metal recycling before reading the article.
  • For this article, it may be beneficial for students to use a graphic organizer or teacher input to ensure comprehension of key concepts.
  • This article can support a lesson on different types of recycling and their positive impact on the environment.
  • This article can enhance a classroom discussion or support student-written informative essays about how much metal recycling is happening in America and how the current rate could increase.
Scientist Notes
This article discusses recycling metals and how focusing on recycling can help reduce greenhouse gas emissions and environmental impacts. The study demonstrates this by predicting how much metal will be needed in the future and calculating the greenhouse gas emissions when different amounts of metal are recycled. The article is organized similarly to a scientific paper in the way it breaks down this climate solution into an introduction, methods, results, discussion, and conclusion sections. The limitations of the study are also included. This structure makes this resource a good example of how scientific articles are often structured. Resources are included. The information presented is accurate and this resource is recommended for teaching.
