In this activity, students investigate different methods (aeration and filtering) for removing pollutants from water. They will design and build their own water filters.

Students learn about the amazing adaptations of the ptarmigan to the alpine tundra. They focus one adaptation, the feathered feet of the ptarmigan, and ask whether the feathers serve to only keep the feet warm or to also provide the bird with floatation capability. They create model ptarmigan feet, with and without feathers, and test the hypothesis on the function of the feathers. Ultimately, students make a claim about whether the feathers provide floatation and support this claim with their testing evidence.

Students use a sponge and water model to explore the concept of relative humidity and create a percent scale.

This website provides users with a new Earth Science related photo daily with description.

quarter of the global fish stocks are regarded as overfished, half of these been exploited to the limits of their capacity. Overfishing occurs when more fish are continuously being caught than naturally proliferate. Scientists fear that many stocks will collapse if the politics and management of fisheries do not change drastically. This means that fisheries activities must be coordinated internationally and that fish as a resource must be handled sustainably by law. From an economic perspective, overfishing is a problem which has developed because fish stocks are a common resource. A fish in the sea belongs to everyone; a caught fish belongs only to the fisherman.

The online game ecoOcean addresses this issue and shows that large catches do not necessarily bring the best results. In ecoOcean the players become fishermen and have to develop the best possible strategy for sustainable fishing.

The Idea
The online game ecoOcean was designed in association with the Cluster of Excellence “The Future Ocean” at Kiel University from the research of the “Sustainable Fisheries” work group.

In “The Future Ocean”, economists, lawyers, fishery biologists, oceanographers and geologists work together on developing new approaches and models for the realisation of a sustainable fisheries management concept.

The CLS provides educational resources for middle and senior years teachers across Canada that relate to curriculum. Resources in the following topics have been developed: Light and Optics; Science and Society; Physical Sciences; Earth Sciences; Health Sciences; Chemistry; Physics; Biology.

This resource provides ways for students to inquire and explore a variety of topics when it comes to producing power, delivering it, conserving it and the ethical, social and environmental considerations that go along with it. As students learn what goes into powering a province, it is hoped that they will also begin a journey of discovering the value of electricity in their lives and the role they can play to use less of it.
This resource was developed to provide teachers with the most up‐to‐date information on electricity in Saskatchewan. As the electrical industry is constantly evolving and regulations and innovations influence new directions, it's important that teachers have current information to share with students.
As much as possible, teachers are forwarded to the SaskPower website as that will have the most current content. Student handouts will be updated annually, but if there is a discrepancy between the printed copy and the website, please defer to the content on saskpower.com.
This resource was developed by SaskPower with input from educators who provided valuable ideas, feedback and expertise.

Empowering Young Learners in a Warming World 3-6 was developed to support teachers in approaching climate change in an age-appropriate way with young students. This resource is a comprehensive guide to climate change education with five different chapters. Each chapter below consists of 3-4 guided inquiries to help bring climate change learning to your young learners.

Each inquiry theme below will begin by presenting background information for teachers about the specific subject matter concerning climate change and give an overview of the associated risks and trends. This guide provides educators with a blend of quality content (resources, videos, books, websites and ideas) and exemplary pedagogy to guide students through an inquiry-driven approach to climate change learning.

Students begin by reading Dr. Seuss' "The Lorax" as an example of how overdevelopment can cause long-lasting environmental destruction. Students discuss how to balance the needs of the environment with the needs of human industry. Student teams are asked to serve as natural resource engineers, city planning engineers and civil engineers with the task to replant the nearly destroyed forest and develop a sustainable community design that can co-exist with the re-established natural area.

Students are introduced to the fundamentals of environmental engineering as well as the global air, land and water quality concerns facing today's environmental engineers. After a lesson and activity to introduce environmental engineering, students learn more about water chemistry aspects of environmental engineering. Specifically, they focus on groundwater contamination and remediation, including sources of contamination, adverse health effects of contaminated drinking water, and current and new remediation techniques. Several lab activities provide hands-on experiences with topics relevant to environmental engineering concerns and technologies, including removal efficiencies of activated carbon in water filtration, measuring pH, chromatography as a physical separation method, density and miscibility.

Students develop critical thinking skills by interviewing a person who has perspective on environmental history. Students explore the concept of a timeline, including historical milestones, and develop a sense of the context of events.

In this activity, students create a "web" to identify and demonstrate the interactions among the living and non-living parts of an environment. This information allows students to better understand what an environment is and to also consider how engineers use teamwork to solve problems.

Students explore the biosphere and its associated environments and ecosystems in the context of creating a model ecosystem, learning along the way about the animals and resources. Students investigate different types of ecosystems, learn new vocabulary, and consider why a solid understanding of one's environment and the interdependence of an ecosystem can inform the choices we make and the way we engineer our communities. This lesson is part of a series of six lessons in which students use their growing understanding of various environments and the engineering design process, to design and create their own model biodome ecosystems.

With a continued focus on the Sonoran Desert, students are introduced to the concepts of food chains and food webs through a PowerPoint® presentation. They learn the difference between producers and consumers and study how these organisms function within their communities as participants in various food chains. They further understand ecosystem differences by learning how multiple food chains link together to form intricate and balanced food webs. At lesson end, students construct food webs using endemic desert species.

This online lesson provides perspectives from Native American community members, images, objects, and other sources to help students and teachers understand the efforts of Native Nations of the Pacific Northwest to protect and sustain salmon, water, and homelands. Scroll to begin an exploration of the Pacific Northwest history and cultures.

Air is one of Earth's most precious resources, and we need to take care of it in order to preserve the environment and protect human health. To this end, students develop their understanding of visible air pollutants with an incomplete combustion demonstration, a "smog in a jar" demonstration, and by building simple particulate matter collectors.
