How do scientists make inferences for something they cannot directly observe? The Black Box approach seems ideal to help students understand how scientists work. Black Boxes are sealed units; their interior is not accessible. The effort to determine their possible content (internal structure) demands successive modifications in hypothesis,…

Studies show that overall seafood consumption in the United States is rising (Agriculture and Agri-Food Canada 2012). Other research estimates that as much as 40% of the seafood caught worldwide is discarded, while countless sharks, whales, dolphins, birds, sea turtles, and other animals are unintentionally killed or injured by fishing gear…

In a regional gathering called the Youth Water Summit, high school students present projects that respond to the driving question behind their science curriculum: "How can you address a significant water resource challenge in your community's watershed?" Students exhibit scientific posters, interactive presentations, films, art projects,…

The Hudson River Watershed contains a variety of geologic, topographic, climatic, and hydrologic features and a diversity of land-use patterns--making it an ideal model for studying human impact on the coastal environment. In this article, the authors present the Hudson River Plume (HRP), a problem-based online module that explores nonpoint-source…

This article discusses "Family Secrets," a problem-based learning (PBL) curriculum module that focuses on the bioethical implications of genetic testing. In high school biology classrooms throughout New York State, students are using "Family Secrets" to learn about DNA testing; Huntington's disease (HD); and the ethical, legal,…

For eight years, relationships with community partners have been the mainstay of a science enrichment program for secondary students. Through the use of problem-based learning, science classes use, the techniques and tools of scientists to solve authentic problems directly related to students' interests and needs. In this article, the author…

All artists are chemists. Artists understand and study the properties of specific materials and find ways to explore these properties to express views of themselves and the world around them. This article discusses the Artist as Chemist unit and presents how students link art and chemistry through problem-based learning activities. In this…
