Students bury various pieces of trash in a plotted area of land outside. After two to three months, they uncover the trash to investigate what types of materials biodegrade in soil.
Students explore the concept of biodegradability by building and observing model landfills to test the decomposition of samples of everyday garbage items. They collect and record experiment observations over five days, seeing for themselves what happens to trash when it is thrown "away" in a landfill environment. This shows them the difference between biodegradable and non-biodegradable and serves to introduce them to the idea of composting. Students also learn about the role of engineering in solid waste management.
Students design and build model landfills using materials similar to those used by engineers for full-scale landfills. Their completed small-size landfills are "rained" on and subjected to other erosion processes. The goal is to create landfills that hold the most garbage, minimize the cost to build and keep trash and contaminated water inside the landfill to prevent it from causing environmental damage. Teams create designs within given budgets, test the landfills' performance, and graph and compare designs for capacity, cost and performance.
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.
This problem based learning (PBL) activity allows students to become educated on how excess waste can harm the environment. This activity then has the students form a plan on how their school can limit trash output in their cafeteria, and then sending a letter to their principle describing their plan.
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.
Waste disposal has been an ongoing problem since medieval times. Environmental engineers are employed to develop technologies to dispose of the enormous amount of trash produced in the United States. In this lesson, students will learn about the three methods of waste disposal in use by modern communities. They will also investigate how engineers design sanitary landfills to prevent leachate from polluting the underlining groundwater.
A group of Scripps graduate researchers recently returned from a 20-day expedition to the ŇGreat Pacific Garbage Patch,Ó a little-studied remote ocean region where plastic debris accumulates. Join Miriam Goldstein, chief scientist on the cruise, and colleagues Pete Davison and Chelsea Rochman, as they discuss the garbage patch, why itŐs there, and how they are exploring and analyzing the problem of plastic in the North Pacific Ocean.

The purpose of this Science NetLinks lesson is to develop an understanding of the impact of improved sanitation on human health. In this lesson, students learn something about the ways that sanitation technology has helped people by examining the history of sanitation in the context of disease outbreaks and comparing the quality of life in those times to that of today. By the end of this lesson, students should recognize that advances in health and human life expectancy have resulted in large part because of technologies that we now take for granted, such as modern waste-disposal, sanitary food handling, and refrigeration.
In this lesson, students explore solid waste and its effects on the environment. They will collect classroom trash for analysis and build model landfills in order to understand the process and impact of solid waste management. Students will understand the role of engineers in solid waste management.
What kinds of garbage break down the fastest, the most and the easiest? When you throw something "away", does it really go away? Find out the answers with this experiment!
In this activity, students work as engineers to build and observe a model landfill. They will understand the process and pitfalls of the use of landfills as a method for the waste disposal.
Students collect, categorize, weigh and analyze classroom solid waste. The class collects waste for a week and then student groups spend a day sorting and analyzing the garbage with respect to recyclable and non-recyclable items. They discuss ways that engineers have helped to reduce the accumulation of solid waste.
Students investigate what types of materials biodegrade in the soil, and learn what happens to their trash after they throw it away. The concepts of landfills and compost piles will be explained, and the students will have an opportunity to create their own miniature landfill in which the difference between organic and inorganic waste will become clear.

In this activity, students will have the opportunity to learn about how trash is separated in Japan. Students will also separate trash into different categories.
