As our closest celestial neighbor, the Moon is a familiar and inspiring object to investigate using a small telescope, binoculars, or even photographs or one of the many high quality maps available online. The wondrously varied surface of the Moon--filled with craters, mountains, volcanic flows, scarps, and rilles--makes the Moon an excellent…

This article describes the High-Adventure Science curriculum unit "Is There Life in Space?" This free online investigation, developed by The Concord Consortium, helps students see how scientists use modern tools to locate planets around distant stars and explore the probability of finding extraterrestrial life. This innovative curriculum…

In this article , the authors describe an activity in which students in Savannah, Georgia, use handheld GPS devices to record the sightings of bottlenose dolphins, examine spatial data from five pairs of dolphins in the study, and then form hypotheses about the spatial patterns they observe. In the process, they learn not only about the ecology of…

In this article the authors share a great activity for teaching the nature of science (NOS). Using a simple Amish pull toy to encourage a high school chemistry class to think about NOS, the authors realized that the activity not only highlighted scientific practices emphasized in the "Next Generation Science Standards" (Achieve Inc.…

The history of science illustrates some exciting--and sometimes controversial--moments. Unfortunately, textbooks tend to focus on results in a scientific discipline and only occasionally showcase an interesting historical vignette, telling the story behind those results. Although required studies may leave teachers little classroom time for…

"The End of Fish" was how Daniel Pauly, professor of fisheries at the University of British Columbia, referred to sobering research showing that--without swift action--populations of all major commercial fish species could collapse by 2048. A lesson on the decline of global fisheries can address many state and national science standards.…

A "Framework for K-12 Science Education" (NRC 2012) and subsequent "Next Generation Science Standards" (Achieve Inc. 2013) will substantially influence the teaching and learning of science in the United States. The "Framework," for example, calls for students to learn about several practices related to scientific…

In this article, Renee Clary and James Wandersee describe the beginnings of "Classification," which lies at the very heart of science and depends upon pattern recognition. Clary and Wandersee approach patterns by first telling the story of the "Linnaean classification system," introduced by Carl Linnacus (1707-1778), who is…

At its core, science is about making sense of the world around us. Therefore, science education should engage students in that sense-making process. Helping students make sense of disciplinary core ideas and crosscutting concepts by engaging in scientific practices is the key innovation of the "Next Generation Science Standards"…

Traditionally, teachers assess students' physics understanding through lab activities, responses to open-ended word problems, and tests. But there is another way to measure student understanding, one in which students apply their learning to the world around them. This article shows how to implement student portfolios, which allow students to…

Since 1996, science education has been guided by the National Science Education Standards (NRC 1996). But now there's a "new sheriff in town" as the "Common Core State Standards" and "A Framework for K-12 Science Education" together become the 21st century's torch bearer for curricula reform in science and…

The author taught for years in rural high schools, where students often helped their parents out around the house or farm with chores, learning basic mechanical skills that he could then build on in class. Then the author taught in an urban high school, where student skills often centered on video games and other electronics. The author knew that…

Science fairs can be good motivators, but as extracurricular activities, they leave some students behind. However, by staging a Science Challenge Day at school, educators can involve all students in doing everything from choosing activities to judging projects. This article presents a model for running a successful Science Challenge Day. The…

Modeling in science has been studied by education researchers for decades and is now being applied broadly in school. It is among the scientific practices featured in the "Next Generation Science Standards" ("NGSS") (Achieve Inc. 2013). This article describes modeling activities in an extracurricular science club in a high…

Scientifically literate citizens need to understand how scientists evaluate competing explanations. Likewise, students must learn to critically evaluate the quality of scientific knowledge and weigh alternative explanations. Regrettably, high school graduates often are not critically evaluative about scientific topics. To help remedy that, this…
