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?

Selected resources provide three web-based activities to complement science lessons in an issue of Beyond Weather and the Water Cycle. The free, online magazine for Grades K-5 teachers explores the essential principles of climate literacy.
Students learn about adaptations of the pink river dolphin through concept mapping, and then they compare pink river dolphins with marine dolphins.
Join Simon, Anita, Emily and the rest of Ms. Patel's class as they gain an understanding of how the Earth works as a system while preparing their end of the school year play.
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.
This article highlights resources related to water from the American Museum of Natural History and at-home activities on ice and water.

The theme of this guide is: achieving ocean health and balance through investigation and data collection techniques that show the necessity for marine sanctuaries, the effects of fisheries and the management practices being followed in today's oceans.
This is a laboratory course supplemented by lectures that focus on selected analytical facilities that are commonly used to determine the mineralogy, elemental abundance and isotopic ratios of Sr and Pb in rocks, soils, sediments and water.
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.
With wisdom and wit, Anupam Mishra talks about the amazing feats of engineering built centuries ago by the people of India's Golden Desert to harvest water. These structures are still used today -- and are often superior to modern water megaprojects. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 17-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.
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.
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.
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.
Science writer Margaret Wertheim re-creates the creatures of the coral reefs using a technique invented by a mathematician -- simultaneously celebrating the amazements of the reef, and deep-diving into the hyperbolic underpinnings of coral creation. A quiz, thought provoking question, and links for further study are provided to create a lesson around the 15-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.
Biology is designed for multi-semester biology courses for science majors. It is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand. To meet the needs of today’s instructors and students, some content has been strategically condensed while maintaining the overall scope and coverage of traditional texts for this course. Instructors can customize the book, adapting it to the approach that works best in their classroom. Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand—and apply—key concepts.
By the end of this section, you will be able to:Define biogeographyList and describe abiotic factors that affect the global distribution of plant and animal speciesCompare the impact of abiotic forces on aquatic and terrestrial environmentsSummarize the affect of abiotic factors on net primary productivity
