Learning science vocabulary is an often tedious but important component of many curricula. Frequently, students are expected to learn science vocabulary indirectly, but this method can hinder the success of lower-performing students (Carlisle, Fleming, and Gudbrandsen 2000). We have developed an inquiry-based vocabulary activity wherein students…

In three semiguided inquiry lessons on population biology, students use models and simulations to examine population trends and make projections. They are guided to create and evaluate data and to use algebraic and geometric representations to examine biotic and logistic growth models as part of examining human population growth. As they recognize…

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…

Although butterflies are a common topic of study in many early childhood classrooms, integrating art production broadens the scope of the study and allows children to deepen their knowledge and understanding through creative self-expression. This article presents a set of integrated activities that focus on helping children fully grasp the process…

This article provides basic information on how a common species of earthworm, "Eisenia fetida," can be used in the biology classroom as well as a discussion of how to establish and care for a vermicompost bin. We discuss ideas for inquiry activities with the organism and provide a sample-guided inquiry that demonstrates how a long-term,…

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.)

Students examine the bacterial expansion pattern and attempt to relate what they discover to expanding powers of two. They also relate what they see and discover to increasing living space requirements in a world of infinite space and finite space to discover that living space decreases as a function of one over expanding powers of two. The…

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…
