Children experiment with freezing water to observe a state change of water, and discover that it is less dense as a solid (ice) than it is as a liquid (water). Amazing Expanding Ice is an overnight activity requiring 20 minutes of preparation, overnight freezing of the experiment, and 10 minutes of follow-up discussion.

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.

In this activity students examine groundwater flow path based on hydraulic head data/ potentiometric surface and spatial variation of groundwater chemistry. Students analyze the data using AquaChem and Phreeqc which is integrated with AquaChem

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.

This lesson is for ABE students at a level D-E Reading level to practice identifying key points in video and text and analyzing the causes and effects of social issues, and identifying solutions to these problems. By watching two short videos and reading materials on the effects of lead exposure and on the specific drinking water crisis in Flint, MI, students will examine key issues, analyze the problem and its causes, identify approaches to solving this problem and ones like it in other locations, and apply this approach to other scenarios that are relevant to their immediate lives.

These 3 lessons are for high ABE/low ASE students at a level D-E Reading level to practice identifying key points in video and text and analyzing the causes and effects of social issues, and identifying solutions to these problems. By watching two short videos and reading EPA materials on the effects of lead exposure and a short article on the specific drinking water crisis in Flint, MI, students will examine key issues, analyze the problem and its causes, identify approaches to solving this problem and ones like it in other locations, and apply this approach to other scenarios that are relevant to their immediate lives.

This quarter-long project forms the basis of a third-year course for majors and nonmajors at the University of Washington, Bothell called Science Methods and Practice. Students use databases to identify novel research questions, and extract data to test their hypotheses. They frame the question with primary literature, address the questions with inferential statistics, and discuss the results with more primary literature. The product is a scientific paper; each step of the process is scaffolded and evaluated. Given time limitations, we avoid devoting time to data collection; instead, we sharpen
students' ability to make sense of a large body of quantitative data, a situation they may rarely have encountered.

We treat statistics with a strictly conceptual, pragmatic, and abbreviated approach; i.e., we ask students to know which basic test to choose to assess a linear relationship vs. a difference between two means. We stress the need for a normal distribution
in order to use these tests, and how to interpret the results; we leave the rest for stats courses, and we do not teach the mathematics. This approach proves beneficial even to those who have already had a statistics course, because it is often the first time
they make decisions about applying statistics to their own research questions.

We incorporate peer review and collaborative work throughout the quarter. We form collaborative groups around the research questions they ask, enabling them to share primary literature they find, and preparing them well to review each other's writing. We encourage them to cite each other's work. They write formal peer reviews of each other's papers, and they submit their final paper with a letter-to-the-editor highlighting how their research has addressed previous feedback.

A major advantage of this course is that an instructor can easily modify it to suit any area of expertise. Students have worked with data about how a snail's morphology changes in response to its environment (Price, 2012), how students understand genetic drift (Price et al. 2014), maximum body size in the fossil record (Payne et al. 2008), range shifts (Ettinger et al. 2011), and urban crop pollination (Waters and Clifford 2014).

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.

A student activity to determine the angle of repose and what factors determine the angle of repose.

Hello Readers, My name is Eddie Joo and I am the co-author as well as the person behind the cover art for this OER. The reason I chose the specific elements on the cover are relatively simple. I dislike the textbooks that just slap random images or things related to the subject and make the cover look really busy. I don't know about you, but any poster or ad that has something to do with Alaska usually includes mountains so I chose the ocean/water instead. Same reason with the animals as the Bear, Wolf, etc. are the go to animals when portraying Alaska so a Dall Sheep, Orca, and an Owl grace the cover. Last but most important to me is the sunrise/sunset gradient. I love seeing both in the winter and is special to me so I added it in as a little Easter egg for me. I hope you enjoy this book! Regards, Eddie

Long Description:
This book is the first edition (Fall 2022) to the exploration of two main core concepts in physiology; Systems Integration, and Homeostasis, in animals at the tissue and organ system level. The flow of this book focuses on how organ systems work together. Foundational homeostatic principles are introduced within the first chapter and threaded throughout the chapters within this text. This text was created by Eddie Joo to supplement students learning within the University of Alaska Anchorage’s Animal Physiology course. The content in this open textbook was adapted from other open textbooks (CC-BY-4.0) resources or created/written by Rachael Hannah and Eddie Joo. This work was funded by an Institutional Development Award (IDeA) from the National Institutes of Health as a Curriculum grant from ALASKA INBRE.

"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..."

"Among the many complications patients with diabetes can experience, cognitive decline is one of them. Diabetes-induced cognitive decline, or DICD, begins with damage to the central nervous system and can result in impaired learning, memory, and judgment. A recent study found that in mice with DICD, injection with the antidiabetic protein FGF1 improved cognition. In a water maze task designed to test memory, diabetic mice treated with FGF1 (db/db+FGF1) reached their goal significantly faster than untreated mice with diabetes (db/db). And the brains of untreated mice (db/db) showed more shrinkage than those of treated mice (db/db+FGF1). Further research should help clarify how FGF1 reduces symptoms of both diabetes and DICD and whether FGF1 might be an effective treatment option for patients with DICD..."
