Sense-making has been described as working on and with ideas--both students' ideas and authoritative ideas in texts--to build coherent storylines, models, and/or explanations. This article describes the process for developing storyline units to support students' making sense of and explaining a rocket launch. The storyline approach, which aligns…

Lab notebooks provide students with authentic science experiences as they become active, practicing scientists. Teachers gain insight into students' understanding of science content and processes, while students create a lasting personal resource. This article provides high school science teachers with guidelines for implementing lab notebooks in…

Graphs represent complex information. They show relationships and help students see patterns and compare data. Students often do not appreciate the illuminating power of graphs, interpreting them literally rather than as symbolic representations (Leinhardt, Zaslavsky, and Stein 1990). Students often read graphs point by point instead of seeing…

After years of using Rube Goldberg-inspired projects to teach concepts of simple machines, the author sought a comparable project to reinforce electricity lessons in his ninth-grade Science and Technology course. The Friendship Detector gives students a chance to design, test, and build a complex circuit with multiple switches and battery-powered…

Teachers strive to engage students in rich and varied experiences involving exploration. These experiences should be accessible to all types of learners (e.g., visual, kinesthetic, mathematically inclined), offering multiple pathways for engagement at different levels of sophistication and accommodating both conceptual and computational…

Adaptation, interactions between species and their environments, and change over time are fundamental principles in biology. They represent aspects of two of the big ideas in science: evolution and natural selection. To help students understand these ideas, the authors developed the "Guppy Game." In this article, they describe the game and how…

The National Science Teachers Association's (NSTA) Science Safety Advisory Board recently launched the Safety in the Science Classroom portal. This portal serves as a gateway to safety resources for teachers, supervisors, and administrators. It also contains an evolving list of safety resources for elementary, middle, and high schools. The list…

Climate change is complex, requiring critical thinking on both local and global scales. Its effects vary dramatically around the world and require new strategies to help students grasp its complexity, scale, and interrelatedness. This article describes a project to help biology students think critically about climate change from a global…

One goal of 21st-century education is to develop mature citizens who can identify issues, solve problems, and communicate solutions. What better way for students to learn these skills than by participating in a science and engineering fair? Fair participants face the same challenges as professional scientists and engineers, even Nobel laureates.…

One way to advance inquiry in the classroom is to establish a systematic strategy for reflecting on our practice and our students' readiness to engage in increasingly complex scientific reasoning. The Matrix for Assessing and Planning Scientific Inquiry (MAPSI) is a tool that promotes this valuable reflection so that we, as teachers, are better…

What makes an outstanding book for a young reader? Although it would be hard to create a rubric for every book, experienced teachers recognize them quickly. They fascinate and captivate with both their content and style. Award-winning trade books inspire young readers to want more... more information, more books, more inquiry, more science. The…

University educators work with preservice teachers who often feel overwhelmed when facing high school science classrooms full of reluctant readers. These struggling students often have various special-education modifications or are English language learners (ELLs) with different degrees of language proficiency. Teachers report that these students…

The National Research Council's recent publication "A Framework for K-12 Science Education: Practices, Crosscutting Concepts, and Core Ideas" (NRC 2011), which is the foundation for the Next Generation Science Standards now being developed, places unprecedented focus on the practices involved in doing scientific and engineering work. In an effort…

Students use manipulative models and small-scale simulations that promote learning of complex biological concepts. The authors have developed inexpensive wet-lab simulations and manipulative models for "Diagnosing Diabetes," "A Kidney Problem?" and "A Medical Mystery." (Contains 5 figures and 3 online resources.)

In their research, scientists generate, test, and modify scientific models. These models can be shared with others and demonstrate a scientist's understanding of how the natural world works. Similarly, students can generate and modify models to gain a better understanding of the content, process, and nature of science (Kenyon, Schwarz, and Hug…
