How do strong and weak acids differ? Use lab tools on your computer to find out! Dip the paper or the probe into solution to measure the pH, or put in the electrodes to measure the conductivity. Then see how concentration and strength affect pH. Can a weak acid solution have the same pH as a strong acid solution?

Advanced Seminar: Urban Nature and City Design
Conditional Remix & Share Permitted
CC BY-NC-SA
Rating
0.0 stars

This course will explore the mutual influences of ideas of nature, theories of city design and planning, and practices of urban design, construction, and management. We will investigate how natural processes shape urban landscapes (from the scale of street corner to region) and how to intervene strategically in those processes in order to achieve certain goals. We will examine cases of cities that adapted successfully to natural processes and those that did not. Students will then have the opportunity to research a case of their choice and to present their findings for discussion. The subject may be historical or an an example of contemporary theory and practice.

All Things Flow: Fluid Mechanics in the Natural Sciences
Conditional Remix & Share Permitted
CC BY-NC
Rating
0.0 stars

This book began as lecture notes for an Oregon State University course in fluid mechanics, designed for beginning graduate students in physical oceanography. Because of its fundamental nature, this course is often taken by students outside physical oceanography, e.g., atmospheric science, civil engineering, physics and mathematics.
In later courses, the student will discover esoteric fluid phenomena such as internal waves that propagate through the sky, water phase changes that govern clouds, and planetary rotation effects that control large-scale winds and ocean currents. In contrast, this course concerns phenomena that we have all been familiar with since childhood: flows you see in sinks and bathtubs, in rivers, and at the beach. In this context, we develop the mathematical techniques and scientific reasoning skills needed for higher-level courses and professional research. Prerequisites are few: basic linear algebra, differential and integral calculus and Newton’s laws of motion. As we go along we discover the need for the more advanced tools of tensor analysis.

In this activity, students discover the relationship between an object's mass and the amount of space it takes up (its volume). Students learn about the concept of displacement and how an object can float if it displaces enough water, and the concept of density and its relationship to mass and volume.

Antibiotic resistance profiles in the Yangtze River

Rating
0.0 stars

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:

"Resistance to antibiotics is a growing global threat to human and animal health. Much of the current research into antibiotic resistance has focused on the human gut, but significantly less of it has examined rivers, which are akin to a terrestrial ‘gut.’ To close this gap, researchers examined the antibiotic resistance genes and their hosts in the 3rd longest river in the world, the Yangtze. They identified 1853 species of antibiotic-resistant bacteria that collectively carried 31 types of antibiotic resistance genes. Human pathogenic bacteria carried a disproportionately large share of the resistance genes. Specifically, human pathogens accounted for 5.9% of the host population found in the river sediment, but they carried 46% of the resistance genes there. In the water column, human pathogens carried 64% of the resistance genes while representing only 13.4% of the host population. The dominant antibiotic resistance genes differed from those found in the human gut, anthropogenic systems, or lakes..."

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

Rating
0.0 stars

This course details the quantitative treatment of chemical processes in aquatic systems such as lakes, oceans, rivers, estuaries, groundwaters, and wastewaters. It includes a brief review of chemical thermodynamics that is followed by discussion of acid-base, precipitation-dissolution, coordination, and reduction-oxidation reactions. Emphasis is on equilibrium calculations as a tool for understanding the variables that govern the chemical composition of aquatic systems and the fate of inorganic pollutants.
This course is offered through The MIT/WHOI Joint Program. The MIT/WHOI Joint Program is one of the premier marine science graduate programs in the world. It draws on the complementary strengths and approaches of two great institutions: the Massachusetts Institute of Technology (MIT) and the Woods Hole Oceanographic Institution (WHOI).

Are Dams Forever?
Read the Fine Print
Educational Use
Rating
0.0 stars

Students learn that dams do not last forever. Similar to other human-made structures, such as roads and bridges, dams require regular maintenance and have a finite lifespan. Many dams built during the 1930-70s, an era of intensive dam construction, have an expected life of 50-100 years. Due to inadequate maintenance and/or for environmental reasons, some of these dams will fail or be removed in the next 50 years. The engineers with Splash Engineering have an ethical obligation to remind Thirsty County of the maintenance and lifespan concerns associated with its dam.

Atlas of the Pacific Northwest
Unrestricted Use
Public Domain
Rating
0.0 stars

This 2018 edition is the first to be released in a digital, fully-interactive format, designed to highlight facets of the Pacific Northwest landscape with novel approaches to data presentation. Where previous editions of the atlas were designed to ask and answer questions, this atlas serves as a platform for the geographically curious to explore the region, providing as many critical questions as it does critical answers.

Beyond this page are maps of the familiar and the unfamiliar. Migration maps highlight human movement between the Pacific Northwest and the rest of the United States; a wildfire timeline chronicles the year-to-year spread of modern and historical fires; and the watershed guide abandons traditional political boundaries in favor of natural, hydrological borders. All data in the atlas were gathered from publically accessible sources, compiled using open-source software and coding libraries. This is an atlas designed to be open, responsive, and to satisfy the geographic curiosity of any and all interested.
