Cookbook labs have been a part of science programs for years, even though they serve little purpose other than to verify phenomena that have been previously presented by means other than through investigations. Cookbook science activities follow a linear path to a known outcome, telling students what procedures to follow, which materials to use,…

The activity described in this article poses a question, provides evidence needed to answer the question, and uses a cooperative learning structure within which students analyze the evidence and create their own questions. Students see how a single cause can interact with two natural systems--the water cycle and the bald eagle food chain--to…

Many science problems require students to convert units. While this skill may not get the attention that more central science concepts do, teachers in the middle school and early high school grades will be doing their students a great service by leaving them with a strong understanding of both the skill itself and the reasons behind it. When the…

Most middle school students comprehend that organisms have adaptations that enable their survival and that successful adaptations prevail in a population over time. Yet they often miss that those bird beaks, moth-wing colors, or whatever traits are the result of random, normal genetic variations that just happen to confer a negative, neutral, or…

In this article, the authors present an inquiry-based approach to facilitate student understanding of the differences among common cloud descriptive characteristics through the use of a semi-dichotomous key developed by a former West Virginia state climatologist. The authors also demonstrate how students can analyze common class data sets that…

As smartphones become more ubiquitous among adolescents, there is increasing potential for these as a tool to engage students in science instruction through innovative learning environments such as augmented reality (AR). Aligned with the National Science Education Standards (NRC 1996) and integrating the three dimensions of "A Framework for K-12…

Discover the secrets contained in fossilized feces. Few topics in middle school classrooms capture students' enthusiasm and interest as do coprolites. These trace fossils offer classroom opportunities for integrated life and Earth sciences study, a stranger-than-fiction history of science, and an opportunity to solve mysteries. (Contains 8…

Students come to class with diverse experiences and backgrounds, and the author tries to take advantage of that diversity in the plant unit. Every year the author secures the help of the two or three green thumbs or green-thumb wannabes to help take care of the collection of plants she brings from home in the fall. The author also invites students…

There was a doughnut thief loose and the students were determined to put their science skills to use to track down the culprit. They would use forensic science to eliminate suspects and identify the thief who stole the doughnuts. School staff take on the role of the likely suspects. It was their goal to develop an interdisciplinary unit that…

"Why do I need to know this if I don't want to be a scientist?" is a question middle school teachers probably hear on a regular basis. In an effort to answer it, the authors have tried to appeal to students' varied interests, and thus developed myriad ways to show students how science is a part of their everyday lives. What is described in this…

Today's youth are increasingly spending more time indoors and less time outside. As a result, many children have a "nature deficit" (Louv 2005) and little awareness of their role in nature. In this article, the first author describes how she shared her passion for nature with her sixth-grade students through nature journaling and how her…

Wind is reemerging as a clean and reliable source of energy--primarily for the production of electricity. This article discusses how to create a pinwheel to explore wind power. It presents a 5E learning-cycle lesson in which students construct a simple pinwheel-type windmill to test the power generated by different designs. Students compare three-…

Explore claims of extraterrestrial life and our efforts to communicate with inhabitants of worlds outside our solar system. Even though there's no "proof positive" for extraterrestrial life-forms of any flavor, we've set the stage for applying a battery of critical-thinking skills to the valid analysis of scientific data. (Contains 3 figures and 5…

Explore how melting ice sheets affect global sea levels. Sea-level rise (SLR) is a rise in the water level of the Earth's oceans. There are two major kinds of ice in the polar regions: sea ice and land ice. Land ice contributes to SLR and sea ice does not. This article explores the characteristics of sea ice and land ice and provides some hands-on…

How do teachers help students realize their place in the universe? How do they teach the relationship among the Earth, Moon, stars, and galaxies during daylight hours? Most teachers assume that astronomy is a difficult subject to teach in the classroom and that without a planetarium little can be learned. In this article, the authors discuss…
