Students are briefly introduced to Maxwell's equations and their significance to phenomena associated with electricity and magnetism. Basic concepts such as current, electricity and field lines are covered and reinforced. Through multiple topics and activities, students see how electricity and magnetism are interrelated.

Electrochemical engineering deals with electrochemical devices like electrolysers, fuel cells, and batteries. While several excellent books exist in this long-standing and still growing field, their focus is usually on chemistry or phenomenology. In this textbook, we focus on mathematical modelling of the physical phenomena involved. Instead of resorting to numerical modelling, the aim is to derive simplified analytical models that maximise understanding.

Porous electrodes, ion mass transport, and multiphase flow are central themes in this book. Examples include modelling the water saturation in a fuel cell diffusion layer, the gas fraction and current distribution in an alkaline water electrolyser, the potential distribution in a binary electrolyte inside porous battery electrode, and the concentration distribution in the flow channel of a redox flow battery. This makes for a diverse, challenging, and stimulating journey, for both students and researchers.

This is a hands-on lab activity about the chemical composition and conductivity of water. Working in groups, learners will: conduct an experiment involving the process of electrolysis, prepare an experiment to better understand the process of ion exchange, discuss and research the "softness" and "hardness" of water, and use the periodic table to identify elements and learn their characteristics. Background information, a glossary and more is included. Materials needed for each student group include a 9-volt battery, two electrodes (e.g. copper strips, or two #2 pencils sharpened at both ends), electrical wire and glass beakers or ceramic saucers. This activity is part of the Aquarius Hands-on Laboratory Activities.

In this activity, learners conduct a simple experiment to see how electrically charged things like plastic attract electrically neutral things like water. The plastic will attract the surface of the water into a visible bump.

This task, by ClimeTime educators, is for 4th grade students. After class discussions about how dams affect rivers, students analyze aerial photographs of the Elwha River taken just before and at intervals after the removal of the Elwha Dam. Students incorporate what they have learned about erosion to explain the phenomenon of change in the turbidity of the water and structure of the beach at the mouth of the river.
Resource includes a student task document, teacher guide, and task facilitation slides.

A learning activity for the "Do You Know That Clouds Have Names?" book in the Elementary GLOBE series. Using information from the book and their observations, students construct a sky scene with trees and buildings as reference points on the ground and cloud types ordered by altitude in the sky. Students will describe clouds using their own vocabulary and will then correlate their descriptions with the standard classifications of cloud types used by the GLOBE Program. The purpose of the activity is to help students identify some of the characteristics of clouds and to enable students to observe clouds, describe them in a common vocabulary, and compare their descriptions with the official cloud names. Students will be able to identify cloud types using standard cloud classification names. They will know that the names used for the clouds are based on three factors: their shapes, the altitude at which they occur, and whether they are producing precipitation.

A learning activity for the "All About Earth: Our World on Stage" book in the Elementary GLOBE series. In pairs, students will create experimental conditions in terrariums in order to study what plants need to live. Variables to study include the presence or absence of soil, water, and sunlight. Students will record the growth of radish plants as well as observations of "the water cycle" in their terrariums. At the conclusion of their experiments, students will share their results with the class and discuss how water, Earth materials, and air are all necessary to support living things. The purpose of the activity is to acquaint students with the hydrosphere, geosphere, atmosphere, and biosphere more closely, to have students use microcosms to study natural phenomena, and to introduce students to the concept of a "fair test" in a scientific investigation. After completing this activity, students will know about the importance of the hydrosphere, geosphere, and atmosphere in supporting the biosphere. They will learn how to set up "fair test", record detailed observations, use drawings as scientific records, make sense of experimental results, and share them publicly.

Several activities that introduce students to the concepts of earth as a series of systems that are all connected. All of the activities reinforce the idea that water, air, soil, and living things all interact in the Earth system. There are several components that educators can choose to use: a book, a play, two activities, and two coloring pages.

Students will learn about magnification and how a magnifying lens works. They will examine a variety of different objects, first without a magnifier and then with a magnifier, and compare what they observe. They will practice observing details of these objects with magnifying lens. The purpose of this activity is for students to learn about observation skills and how tools can help people make observations, what "magnification" means, and to learn that scientists use tools, such as magnifying lenses, to examine objects. Students will be able to identify a magnifying glass and its purposes. They will be able to describe how the same object looks different when using the unaided eye versus a magnifying lens.

Students will use various objects in the classroom to experiment with nonstandard measurement. They will make estimates and test them out. Then, working in pairs or small groups, students will use a ruler or a measuring tape to become familiar with how to use these tools for standard linear measurement. The purpose of this activity is to practice making standard and non-standard measurement and to learn the purpose of making linear measurements and how to apply them to scientific investigations. Students will learn how to make measurements, both nonstandard and standard (with a ruler). They will test their estimates and record their results.

Students learn about the water cycle and hydrology through a series of three lessons, two coloring book pages, and an e-Book. The themes covered in this resource tie into Climate Science and fundamental climate principles, as well as, engages students in scientific methods.

Students will be introduced to different species of macroinvertebrates. They will hypothesize why each insect looks the way it does. Then students will make observations of macroinvertebrates. in an aquarium in their classroom. For an optional extension, teachers can take students to a local stream or pond to conduct field observations. The purpose of this activity is to introduce students to hydrology and the study of macroinvertebrates. and to understand how macroinvertebrates. help scientists understand water quality. After completing this activity, students will have an understanding of what macroinvertebrates. are and why scientists study them.

A learning activity for the "All About Earth: Our World on Stage" book in the Elementary GLOBE series. One of the "big ideas" in Earth system science is the notion of interaction among parts of the Earth system. In the Elementary GLOBE book All About Earth: Our World on Stage, the children in Ms. Patel's class discuss instances of how the four major spheres of Earth's system interact. They symbolize these interactions by using large arrows to link the system components: air, water, soil, living things and the Sun. In this activity, students continue to explore the idea of interaction among Earth components as they identify processes in the Earth system and indicate how they illustrate an interaction between two of the Earth system components. The purpose of the activity is to help students deepen their understanding of interconnections among Earth's systems, help students to identify processes where Earth's systems are interacting, and to provide practice in the observation and recording of natural phenomena. After completing this activity, students will understand that Earth system interactions are all around them, going on all the time, and that Earth's processes are interconnected. They will learn how to make observations and identify the interactions they illustrate.

Salmon play an important role in the ways of life, culture, history, and resilience of the tribes of this region. The tribes of Washington State and the Pacific Northwest have always depended on salmon as a primary source of food. Overfishing, roads, dams, pollution, and other human practices have been a growing threat to the survival of salmon, which has impacted fishing, salmon-eaters, and the environment. These lessons introduce to children the role of salmon in the history and culture of the first peoples of our region.

The Honoring the Salmon lessons are designed to be taught as a series but can also be taught individually, adapted for each grade level, K-3. They can easily be integrated into science units on salmon, water or watersheds. Content knowledge from these lessons can provide background knowledge for 3rd grade and 4th grade Social Studies CBAs.

NOTE: These lessons are designed around fiction and non-fiction books that are not a part of the STI curriculum. Most of them are easily available through public libraries. Some may need to be purchased.

These lesson resources align to additional Washington State Social Studies, English Language Arts, Environmental and Sustainability, and Social Emotional Learning standards. A full standard curriculum document is included at the bottom of the Pathway 2 introduction page.

This interactive exhibition features the preliminary research reflecting the diverse and inclusive practices of our cohort. Join us as we explore inclusive practices from spaces and communities to workplaces and systems. Our individual exhibits have been classified into five categories, inspired by the ‘Five Elements’ in Taoism. The belief is everything in the universe is made of five elements: metal, wood, water, fire, and earth. These elements are interconnected and fluid. The focus is on ‘energy’ and ‘process’ and how all things can be inclusive and unified. In many ways, the journey to inclusion is reflective of this interconnected, fluid process.

A Fifty-Year Science Adventure

Short Description:
Originally published in 1976 and newly revised for the 50th anniversary of the Hubbard Brook Ecosystem Study, "The Endless Chain of Nature" follows the scientific adventures of student and professional researchers working in a small "closed" ecosystem in the Hubbard Brook Forest in New Hampshire. Written for middle-school readers and older, "The Endless Chain" introduces key ecological ideas in an engaging story of people solving puzzles and mysteries.

Long Description:
This real-life science adventure opens a window into a forest ecosystem in New Hampshire, and an experiment that has gone on for fifty years — so far.

In a three-hundred-year old old farmhouse near a forest lake filled with fish, tadpoles and splashing children, young people and professionals work side by side to solve puzzles about how land, water, living things, and the climate all fit together and all affect each other. The team includes students, teachers, and leading scientists from around the world.

Together they examine a closed ecosystem in the Hubbard Brook Experimental Forest — one of the first Long Term Ecological Research sites. In the past half-century it has led to important discoveries, including what we now know as acid rain. Their work is a fascinating study of the complex relationship between organisms and the environment.

Out in the woods, the team nets birds with the ornithologist, sifts through debris for insects with the entomologist, goes fishing with the ichthyologist, climbs trees with the botanist, chases salamanders with the herpetologist, and digs ancient mud cores out of the bottom of the lake with the paleobotanist. One student researcher — the grandson of a scientist who worked at the Brook in its earlier days — measures trees to help understand what affects their growth.

Using techniques that are both basic and advanced, they carry on experiments begun 50 years ago to see what has changed, and to figure out why. We see the ecology puzzle fit together into a picture of the complex and fascinating chain of nature, and we discover how our lives and actions affect other links in the chain. Surprises are in store in every chapter.

2013 marks the 50th Anniversary of the launching of the Hubbard Brook Ecosystem Study. This pioneering effort to explore the complex ways in which water, air, soil, plants and animals interact began in 1963 in a 3,160 hectare reserve in New Hampshire. It became, and remains today, a world-renowned laboratory yielding many important insights, including identifying the phenomena of acid rain and enhancing the understanding of the impact of climate change on natural systems.
