In this paper we present a critical analysis of some of the arguments of flat Earth theory, and we also try to show that this analysis and refutation of these false claims can be a useful exercise in critical thinking that is so much needed today. This article can also make it easier for teachers who are exposed to some of the arguments of flat…

This column contains exercises to challenge content knowledge. This month's issue discusses ways to remove CO[subscript 2] from the atmosphere.

The purpose of this descriptive study was to examine teacher instructional dilemmas and opportunities that emerged when students worked with interactive computer-based simulation models during the High-Adventure Science (HAS) project. The intervention included the HAS digital curriculum, designed for grades 7-12. Each curricular unit was framed to…

As society becomes more technological, the need for scientific literacy grows . Part of scientific literacy is understanding the nature of science, which can be revealed, in part, by learning the historical context of current science concepts. History of science can be taught using scientific inquiry, scientific argumentation, and authentic…

Earth's surface is constantly changing. Weathering, erosion, and deposition break down Earth materials, transport those materials, and place them in new locations. Children see evidence of these processes all around them. The sidewalk or playground surface cracks and has plants growing in it. Pieces of a rock wall or the sides of a building…

For scientists, the sandbox serves as an analog for faulting in Earth's crust. Here, the large, slow processes within the crust can be scaled to the size of a table, and time scales are directly observable. This makes it a useful tool for demonstrating the role of inquiry in science. For this reason, the sandbox is also helpful for learning…

In the activities presented in this article, students mimic real scientists while constructing predictions and scientific explanations about surface currents. The activities are inspired by and couched within true scientific inquiries regarding the ocean and the North American Great Lakes. Students engage in a classroom inquiry and use map-reading…

Featuring an increased emphasis on the way today's changing science and technology is shaping our culture, this Second Edition of "Teaching Science in Elementary and Middle School" provides pre- and in-service teachers with an introduction to basic science concepts and methods of science instruction, as well as practical strategies for the…

In this extended earth science activity, students create a hands-on model of a volcano to achieve an understanding of volcanic structure, lava flows, formation of lava layers, and the scientific work of archaeologists and geoscientists. During this simulation activity, students have opportunities to learn science as inquiry and the nature of…

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…

This book includes 20 science activities in the fields of scientific method, earth science, life science, and physical science. Each activity is composed of two parts--an explanatory section for the teacher and a student lab sheet. The explanatory section begins with a brief introduction designed to give an overview of the activity's main concept.…

This program guide is meant to help teachers assist their students in viewing the six-part public television series, "Stephen Hawking's Universe." The guide features program summaries that give background information and brief synopses of the programs; previewing activities that familiarize students with the subject; vocabulary that…

This resource book includes 163 science activities for both preservice and in-service teachers. Activities have been field-tested and are cross-referenced according to the processes of science and the content area covered. Each activity has been written to evoke ideas from the reader, thus enabling each activity to serve a base for additional…
