The eastern oyster, "Crassostrea virginica," is an ecologically and economically important species in Chesapeake Bay. Oysters are ecologically unique in the Chesapeake Bay because they build a structure known as a bar or reef by attaching to one another over a 45 long period of time. They have been coined the "Ecological Engineers…

This article describes an arts- and spatial thinking skill--integrated inquiry project applied to life science concepts from the Next Generation Science Standards for fourth grade students that focuses on two unifying or crosscutting themes: (1) structure (or "form") and function and (2) use of models. Students made observations and…

This activity explores the cycling of carbon between the atmosphere (primarily as CO[subscript 2]) and biomass in plants, animals, and microscopic organisms. Students design soil respiration experiments using a protocol that resembles current practice in soil ecology. Three methods for measuring soil respiration are presented. Student-derived…

There is a particular need for inquiry-based lessons in the early elementary grades, when students are starting to develop their analytical skills. In this article, the authors present a 2-tiered inquiry-based lesson plan for 1st and 2nd grades that has been successfully used by graduate teaching fellows involved in the National Science Foundation…

In the project presented in this article, high school students create and observe miniecosystems in an ecology unit designed around a 5E (engagement, exploration, explanation, elaboration, and evaluation) instructional model. Students choose a wide variety of organisms and use creativity to design miniecosystems. (Contains 1 table and 3 figures.)

In this article, the authors describe an integrated science and literacy instructional model in which students build background knowledge by engaging in free-choice learning options during an investigation of school yard habitats. Students interact with their peers while inquiring, discussing findings, and using print resources to enhance learning.

In this extended biology, ecology, and earth science activity, students construct hands-on models of natural wastewater treatment and wastewater treatment facilities to achieve an understanding of wastewater treatment process in nature and wastewater treatment facilities. During this simulation activity, students have opportunities to learn…

In this activity students examine burrow casts to learn about burrowing animals and practice their math skills. Students compute the volume and average circumference of a burrow. They also determine whether a relationship exists between burrow volume and the size of the organism that created it. Students use science as inquiry as they analyze and…

The best place for students to begin to understand complex environmental relationships is in their own back yards. Doing investigations of ants allows students to establish a baseline survey of ant fauna, test the importance of ants in nutrient cycling and soil structure maintenance, and increase their understanding of the environment and their…

In this activity, students learn about the important topic of invasive species, specifically Zebra Mussels. Students role-play different characters in a real-life situation: the trial of the Zebra Mussel for unlawful disruption of the Great Lakes ecosystem. Students will also learn about jurisprudential inquiry by examining the trial process. This…
