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).

As America grew, Americans were destroying its natural resources. Farmers were depleting the nutrients of the overworked soil. Miners removed layer after layer of valuable topsoil, leading to catastrophic erosion. Everywhere forests were shrinking and wildlife was becoming more scarce.
This University of California College Prep (UCCP) Advanced Placement (AP) Environmental Science online course has five objectives: Describe the six different forms of energy and the type of work done by each form. Discuss the roles of sources and sinks in an energy budget. Define the Law of Conservation of Energy, and explain how the operation of fuel cell vehicles illustrates this principal. Name the units with which energy, power, and force are measured and described. Use energy flow within a house to explain both theoretical and practical aspects of energy use and conservation.
Human activities release a variety of substances into the biosphere, many of which negatively affect the environment. Pollutants discharged into the environment can accumulate in the air, water, or soil......
This text is designed to acquaint students with the physical, ecological, social, and political principles of environmental science. Scientific method is used to analyze and understand the interrelationships between humans and the natural environment. This test shows how ecological realities and the material desire of humans often clash, leading to environmental degradation and pollution.
Environmental issues are a concern of many, if not most, Americans. However, there is considerable disagreement on how such issues should be handled. Different people can interpret even a very general issue such as conservation very differently. Some believe that conservation means limiting the use of resources to allow a resource to last longer. Others see the conservation of resources as a way to maximize benefits to humans. This utilitarian approach to conservation policy, would place no value on saving endangered species that provide no direct benefit to humans. At the other extreme, some envision conservation as meaning the protection of resources without regard to profit or material benefit to humans. This view places the preservation as being of the utmost importance, and is sometimes viewed as elitist.
Soil plays an important role in land ecosystems. In order for a community of producers and consumers to become established on land, soil must be present. Furthermore, soil quality is often a limiting factor for population growth in ecosystems. Soil is a complex mixture of inorganic materials, organic materials, microorganisms, water and air. Its formation begins with the weathering of bedrock or the transport of sediments from another area. These small grains of rock accumulate on the surface of the earth. There they are mixed with organic matter called humus, which results from the decomposition of the waste and dead tissue of organisms. Infiltrating rainwater and air also contribute to the mixture and become trapped in pore spaces. This formation process is very slow (hundreds to thousands of years), and thus soil loss or degradation can be very detrimental to a community.
At this point in the unit, students have learned about Pascal's law, Archimedes' principle, Bernoulli's principle, and why above-ground storage tanks are of major concern in the Houston Ship Channel and other coastal areas. In this culminating activity, student groups act as engineering design teams to derive equations to determine the stability of specific above-ground storage tank scenarios with given tank specifications and liquid contents. With their floatation analyses completed and the stability determined, students analyze the tank stability in specific storm conditions. Then, teams are challenged to come up with improved storage tank designs to make them less vulnerable to uplift, displacement and buckling in storm conditions. Teams present their analyses and design ideas in short class presentations.
Students are provided with an introduction to above-ground storage tanks, specifically how and why they are used in the Houston Ship Channel. The introduction includes many photographic examples of petrochemical tank failures during major storms and describes the consequences in environmental pollution and costs to disrupted businesses and lives, as well as the lack of safety codes and provisions to better secure the tanks in coastal regions regularly visited by hurricanes. Students learn how the concepts of Archimedes' principle and Pascal's law act out in the form of the uplifting and buckling seen in the damaged and destroyed tanks, which sets the stage for the real-world engineering challenge presented in the associated activity to design new and/or improved storage tanks that can survive storm conditions.
Students conduct a simple experiment to model and explore the harmful effects of acid rain (vinegar) on living (green leaf and eggshell) and non-living (paper clip) objects.
Students are introduced to the differences between acids and bases and how to use indicators, such as pH paper and red cabbage juice, to distinguish between them.
The information presented in each ActionBioscience.org article has been correlated to the U.S. National Science Education Standards (NSES). Articles may be listed below in more than one category of the standards and educators may determine other curricular applications for the articles.
An alternative introduction to the chapter "Adapting and Living Together" - explained with Vamipres! It sits within the Ecology and Environment topic of the virtual school GCSE Biology. Teachers can choose which engagement video is better for their own uses and students.
Learn about how organisms adapt to their habitats. This video is part of The Virtual School's "Adapting and Living Together" chapter within our Ecology and Environment topic.
An introduction to the chapter "Adapting and Living Together" within the Ecology and Environment topic of the virtual school GCSE Biology.
This unit looks at two topics that are of immense worldwide social, economic, ethical, and political importance -"addiction' and"neural ageing'. You will develop a Master's level approach to the study of specific issues within these two important subject areas.
By watching and performing several simple experiments, students develop an understanding of the properties of air: it has mass, it takes up space, it can move, it exerts pressure, it can do work.
Students are introduced to the concept of air quality by investigating the composition, properties, atmospheric layers and everyday importance of air. They explore the sources and effects of visible and invisible air pollution. By learning some fundamental meteorology concepts (air pressure, barometers, prediction, convection currents, temperature inversions), students learn the impact of weather on air pollution control and prevention. Looking at models and maps, they explore the consequences of pollutant transport via weather and water cycles. Students are introduced to acids, bases and pH, and the environmental problem of acid rain, including how engineers address this type of pollution. Using simple models, they study the greenhouse effect, the impact of increased greenhouse gases on the planet's protective ozone layer and the global warming theory. Students explore the causes and effects of the Earth's ozone holes through an interactive simulation. Students identify the types and sources of indoor air pollutants in their school and home, evaluating actions that can be taken to reduce and prevent poor indoor air quality. By building and observing a few simple models of pollutant recovery methods, students explore the modern industrial technologies designed by engineers to clean up and prevent air pollution.
In this interactive activity adapted from Air Quality Index: A Guide to Air Quality and Your Health by the U.S. EPA, learn about common pollutants in the air we breathe, their health effects, and how their levels are reported.
SPARK tails artists Jim Denevan and Cris Drury as they create large earth works. This Educator Guide is about the history and tradition of artists making work in and about the natural environment.
