Students reasoning with data in an authentic science environment had the opportunity to learn about the process of science and the world around them while developing skills to analyze and interpret self-collected and secondhand data. Our results show that nearly 50% of the treatment group responses were accurate when describing the reason for…

Background: Through the human-centered design process (HCD), students, referred to as learners, can use a personal lens to contextualize engineering concepts and solve real-world problems (Goldman and Kabayadondo 2016). The Ignite program, created by the Center for Global Women's Health Technologies (GWHT) at Duke University, integrates the HCD…

This booklet is intended to help teachers in Florida manage the growing interest in environmental education. Fourteen experiments are grouped into the environmental areas of the water cycle, groundwater, water pollution, waste and water treatment, air pollution, and field experiments. Experiments include demonstrations of the water cycle, the…

The purpose of this study is to examine changes in pre-service science teachers' entrepreneurship mindsets during engineering design-based activities. A holistic single-case study was used in the study. Twenty-eight pre-service teachers carried out engineering design-based activities (five weeks, 20 hours) in the science teaching laboratory…

This publication is the examination booklet used for a home study course in water treatment. This course is the advanced part of a series produced by the Department of the Navy. This publication is designed to be used in conjunction with a course textbook. Each of the four examinations contained in this document are referenced to a specific…

This commentary on sources of water pollution and water pollution treatment systems is accompanied by graphic illustrations. Sources of pollution such as lake bottom vegetation, synthetic organic pollutants, heat pollution, radioactive substance pollution, and human and industrial waste products are discussed. Several types of water purification…

Coagulation is an important process in the context of water purification; and the seed protein of the moringa tree ("Moringa oleifera") is a remarkably effective coagulant. The laboratory course described here is designed to provide high-school students with a stepwise, hands-on experience in investigating the protein-rich coagulant…

Safe and high-quality water is essential from both the health and environmental perspectives. Water quality is so important that the United Nations has included water in the 17 Sustainable Development Goals of the 2030 Agenda for Sustainable Development. Thus, the adequate control and treatment of water are necessities. These tasks must be…

One of three in a series about pollution, this teacher's guide for a unit on water pollution is designed for use in junior high school grades. It offers suggestions for extending the information and activities contained in the textual material for students. Chapter 1 discusses the problem of water pollution and involves students in processes of…

An interactive, field-based course on the environmental aspects of natural water was developed as part of STEM initiatives at a comprehensive university in the United States. The project is funded by the National Science Foundation. The course is focused on two fundamental student skills, such as hydrologic field procedures and analytical methods.…

Background: To prepare K-12 students for the globalizing Science, Technology, Engineering, and Mathematics (STEM) workplace, teachers must utilize pedagogies to improve students' 21st century skills, specifically in communication. Project Based Learning (PBL) has evidenced success in enhancing students' communication skills, while global…

Most forensic chemistry experiments focus on the usual suspects involving criminal scenarios: illicit drug identification, gunshot residue detection, blood and fingerprint analysis, and arson investigations. However, environmental forensics involves chemical techniques that can expand the breadth of experience for forensic chemistry students. An…

This article describes how a university and a museum have worked together to create a "How science works" workshop entitled "What's in our water?" The workshop teaches students about the continuing pollution from a disused coal mine, how the pollution is cleaned up using a state-of-the-art treatment works and how scientists…

This work developed the Flint, Michigan water crisis as a modular case study for teaching traditional analytical chemistry concepts through the medium of environmental justice, power, and equity. An interdisciplinary framework was used to design, implement, and assess the case study in an effort to understand how the deliberate presence of…

This booklet for children emphasizes the exploration and protection of the environment. An introduction discusses the interaction between humankind and the environment, emphasizing that the earth is a closed system. Chapter 1, "Mission: Protect the Water," addresses human dependence on water, water pollution, and water treatment. Chapter…
