This unit covers the processes of photosynthesis, extinction, biomimicry and bioremediation. In the first lesson on photosynthesis, students learn how engineers use the natural process of photosynthesis as an exemplary model of a complex yet efficient process for converting solar energy to chemical energy or distributing water throughout a system. In the next lesson on species extinction, students learn that it is happening at an alarming rate. Students discover that the destruction of habitat is the main reason many species are threatened and how engineers are trying to stop this habitat destruction. The third lesson introduces students to the idea of biomimicry or looking to nature for engineering ideas. And, in the fourth and final lesson, students learn about a specialty branch of engineering called bioremediation the use of living organisms to aid in the clean up of pollutant spills.

Fossils are a glimpse into the distant past and fascinate young and old alike. This unit will introduce you to the explosion of evolution that took place during the Palaeozoic era. You will look at the many different types of creatures that existed at that time and how they managed to evolve to exist on land.

This kit covers a historical overview of American representations of endangered species from the slaughter of the American buffalo to Palm plantations in Sumatra. It compares conflicting constructions about human/animal relations, rainforest biodiversity, the Northern Rockies gray wolf, frogs and Atrazine. Students decode how the relationship of animals and humans has been portrayed and passed on from generation to generation.

This activity illustrates the interrelationship between science and engineering in the context of extinction prevention. There are two parts to the activity. The first part challenges students to think like scientists as they generate reports on endangered species and give presentations worthy of a news channel or radio broadcast. The second part puts students in the shoes of engineers, designing ways to help the endangered species.

In this video segment from Evolution: "Extinction!", geologist Peter Ward discusses evidence for a Permian-Triassic mass extinction.

Psychology is designed to meet scope and sequence requirements for the single-semester introduction to psychology course. The book offers a comprehensive treatment of core concepts, grounded in both classic studies and current and emerging research. The text also includes coverage of the DSM-5 in examinations of psychological disorders. Psychology incorporates discussions that reflect the diversity within the discipline, as well as the diversity of cultures and communities across the globe.Senior Contributing AuthorsRose M.

This resource is a video abstract of a research paper created by Research Square on behalf of its authors. It provides a synopsis that's easy to understand, and can be used to introduce the topics it covers to students, researchers, and the general public. The video's transcript is also provided in full, with a portion provided below for preview:

"Behind every plant is a community of microbes that support its growth, development, and evolution. Currently, these communities are in danger. Overpopulation, overconsumption, and intensive agriculture are seriously altering the plant microbiome. Signature changes include community imbalance and loss of resilience among plant microbes, and increased resistance to antibiotics, which could result in the emergence of new plant as well as human pathogens. Curbing these effects will require increased effort among microbiome scientists to understand the drivers of systemic shifts and among citizens to acknowledge and reduce their footprint on the planet..."

The rest of the transcript, along with a link to the research itself, is available on the resource itself.

This video from Kentucky's Last Great Places shows how the Green River has remained unusually clean and why it is home to several endangered aquatic species.

Extinction is a fact of modern life. Humanity's relentless encroachment on the wilderness has marred the diversity of life with conspicuous gaps where the Tasmanian tiger, the Passenger Pigeon, the Ivory-billed Woodpecker, and countless others used to be. As these extinctions accumulate, the Earth inches closer and closer to its sixth mass extinction. We are all too familiar with the concept of mass extinction - a disaster strikes and sets off a chain of events that result in a massive die-off. But you may not have considered what comes next: what happens to surviving species in the wake of a massive extinction event? Recent research suggests that mass extinctions shake up life on Earth in surprising ways.
