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).
Hank gives the run down on the top five ways humans are negatively impacting the environment and having detrimental effects on the valuable ecosystem services which a healthy biosphere provides.
These free web based tools help teachers to demystify the data and create authentic learning experiences for students. The goal is to have students "ask questions to clarify evidence of the factors that have caused the rise in global temperatures over the past century". The field of climate change is very dynamic and always changing. These six tools incorporate up-to-date practices and can be used immediately in the classroom to help students become true climate change scientists:

- NASA Global Climate Change - Vital Signs of the Planet (6-12) - Explore satellite evidence
- Climate Kids - NASA's Eyes on the Earth (3-6) - Engage early learners
- Global Oneness Project (9-12) - Build empathy
- Earth-Now 6-12 - Analyze real data
- Our Climate Our Future (6-12) - Inspire action
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.
As emissions of heat-trapping bases accumulate in our atmosphere, Earth's polar regions are warming more quickly than at lower latitudes. The rapid environmental changes that result from this warming can have a significant impact on the physical and mental health of rural Alaskans: unpredictable weather and changes in the seasons have made harvesting food more difficult, hazardous, and stressful. The risk of physical injury has also increased, as poor ice, extreme weather, and coastal erosion bring new travel hazards. Increasingly difficult harvest conditions for fish, shellfish, berries, caribou, and sea mammals have also increased concerns about food security. Additionally, declines in snow pack, the threat of drought, changes in lake and river conditions, and damage and disruptions to community water systems have prompted concerns of water security. The climate-related challenge faced by Alaskas tribal health system is to recognize new health stressors and community vulnerabilities, and then find healthy adaptation strategies in an increasingly uncertain future.
In 2012, water managers in Fredericktown, Missouri, saw their city's main source of water dwindle. They used the EPAs Climate Ready Water Utilities program to consider options and develop plans to protect their water source.
After catastrophic flooding in New Orleans destroyed two hospitals, the Southeast Louisiana Veterans Health Care System is planning a replacement facility that will incorporate resilience against future extreme events.
Widespread damage from flooding at the Texas Medical Center in Houston revealed the complex's vulnerabilities. Implementing a long-term hazard mitigation plan is reducing future risks.

An inquiry-based resource for Environmental Sciences 20 that contains two learning modules that help students explore the science of plants and soil as a means to investigate larger themes of production, technology, and sustainability in Saskatchewan.
The AirData Web site gives you access to air pollution data for the entire United States. Want to know the highest ozone level measured in your state last year? Ever wonder where air pollution monitoring sites are located? Are there sources of air pollution in your town? You can find out here! AirData produces reports and maps of air pollution data based on criteria that you specify.
Students are introduced to measuring and identifying sources of air pollution, as well as how environmental engineers try to control and limit the amount of air pollution. In Part 1, students are introduced to nitrogen dioxide as an air pollutant and how it is quantified. Major sources are identified, using EPA bar graphs. Students identify major cities and determine their latitudes and longitudes. They estimate NO2 values from color maps showing monthly NO2 averages from two sources: a NASA satellite and the WSU forecast model AIRPACT. In Part 2, students continue to estimate NO2 values from color maps and use Excel to calculate differences and ratios to determine the model's performance. They gain experience working with very large numbers written in scientific notation, as well as spreadsheet application capabilities.
Students are introduced to air masses, with an emphasis on the differences between and characteristics of high- versus low-pressure air systems. Students also hear about weather forecasting instrumentation and how engineers work to improve these instruments for atmospheric measurements on Earth and in space.
Students learn what causes air pollution and how to investigate the different pollutants that exist, such as toxic gases and particulate matter. They investigate the technologies developed by engineers to reduce air pollution.
As reduced sea ice conditions bring increased shipping and development opportunities to the Arctic, Alaska Native Village Corporations are at the table with resource developers, representing the interests of their people and land.
Tribal communities in southeastern Alaska are partnering with federal and state agencies to investigate increasing harmful algal bloomsevents that pose human health risks to subsistence harvesters.
In Florida's humid climate, strawberry growers are in a constant battle with two kinds of fruit rot. Using a decision support system, they can save money by spraying fields only when the plant diseases are a threat.
Worldchanging.com founder Alex Steffen argues that reducing humanity's ecological footprint is incredibly vital now, as the western consumer lifestyle spreads to developing countries. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 10-minute video. Educators may use the platform to easily "Flip" or create their own lesson for use with their students of any age or level.
Commercial fishing nets often trap "unprofitable" animals in the process of catching target species. In this activity, students experience the difficulty that fishermen experience while trying to isolate a target species when a variety of sea animals are found in the area of interest. Then the class discusses the large magnitude of this problem. Students practice data acquisition and analysis skills by collecting data and processing it to deduce trends on target species distribution. They conclude by discussing how bycatch impacts their lives and whether or not it is an important environmental issue that needs attention. As an extension, students use their creativity and innovative skills to design nets or other methods, theoretically and/or through hands-on prototyping, that fisherman could use to help avoid bycatch.
Bycatch, the unintended capture of animals in commercial fishing gear, is a hot topic in marine conservation today. The surprisingly high level of bycatch about 25% of the entire global catch is responsible for the decline of hundreds of thousands of dolphins, whales, porpoises, seabirds and sea turtles each year. Through this curricular unit, students analyze the significance of bycatch in the global ecosystem and propose solutions to help reduce bycatch. They become familiar with current attempts to reduce the fishing mortality of these animals. Through the associated activities, the challenges faced today are reinforced and students are stimulated to brainstorm about possible engineering designs or policy changes that could reduce the magnitude of bycatch.
