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?

Students learn about the differences between types of water (surface and ground), as well as the differences between streams, rivers and lakes. Then, they learn about dissolved organic matter (DOM), and the role it plays in identifying drinking water sources. Finally, students are introduced to conventional drinking water treatment processes.

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.

This design challenge moves your students from passive to active learners through a cross-curricular, hands-on team challenge in direct correlation to real-world issues of water conservation. Through this lesson,  students in grades 6-8 will create a model of an aquifer to understand the structure of aquifers, how aquifers impact our freshwater supply and groundwater in regards to the water cycle.

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.

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.

As an introduction to bioengineering, student teams are given the engineering challenge to design and build prototype artificial limbs using a simple syringe system and limited resources. As part of a NASA lunar mission scenario, they determine which substance, water (liquid) or air (gas), makes the appendages more efficient.

Atlas of the Pacific Northwest
Read the Fine Print
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.

Biochar: Measuring and Improving Soil Function
Read the Fine Print
Educational Use
Rating
0.0 stars

Students learn how to manipulate the behavior of water by using biochar—a soil amendment used to improve soil functions. As a fluid, water interacts with soil in a variety of ways. It may drain though a soil’s non-solid states, or its “pores”; lay above the soil; or move across cell membranes via osmosis. In this experiment, students solve the specific problem of standing water by researching, designing, and engineering solutions that enable water to drain faster. This activity is designed for students to explore how biochar helps soils to act as “sponges” in order to retain more water.

Biochemistry: Free For All

We are happy to welcome you to our second Open Educational Resource (OER) textbook, Biochemistry Free For All. Biochemistry is a relatively young science, but its rate of growth has been truly impressive. The rapid pace of discoveries, which shows no sign of slowing, is reflected in the steady increase in the size of biochemistry textbooks. Growing faster than the size of biochemistry books have been the skyrocketing costs of higher education and the even faster rising costs of college textbooks. These unfortunate realities have created a situation where the costs of going to college are beyond the means of increasing numbers of students.
