In this paper, we present a physical modeling activity whose objective is to allow students to determine the differences between a disk and a sphere using pure scientific criteria. Thereunto, we reproduce the Sun-Earth-Moon system with low-cost materials and compare the illumination effects on the Moon considering two possible shapes for it (a…

In a series of 12 project-based learning lessons, a group of seven fifth-grade students who live 200 miles from the coast explored their personal connections to the ocean. After completing a unit on the role of water in Earth's surface processes, the students investigated ocean acidification and how this pervasive ocean problem impacts their local…

Tomlinson's explanation of Artful Teaching and her 2017 expansion of this concept The Five Key Elements of Differentiation provide the theoretical framework of this examination of the need for science investigations in elementary schools. The Artful Teaching framework uses an equilateral triangle with vertices labeled The Teacher, The Student, and…

To help teachers enrich their students' understanding of inquiry in Earth science, this article describes six modes of inquiry used by practicing geoscientists (Earth scientists). Each mode of inquiry is illustrated by using examples of seminal or pioneering research and provides pointers to investigations that enable students to experience these…

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…

Uses a university campus as the focus for a study of the entire watershed. Presents a context for incorporating pedagogical elements, interdisciplinary teaching, research experience, and active, collaborative strategies into a useful framework for undergraduate science education. (Author/KHR)

Describes a lab investigation designed to introduce students to soil compaction and help them to learn to design and adapt procedures that scientists use when they plan and conduct controlled investigations. Provided are objectives, a list of materials, procedures, and a sample student handout. (CW)

Describes a demonstration to show the character and behavior of mixing clouds. Discusses laminar and turbulent flow, and the formation of contrails and other cloud phenomena. (CW)

INCLUDED IN THIS MANUAL WRITTEN FOR SECONDARY SCHOOL AND COLLEGE TEACHERS ARE DESCRIPTIONS OF DEMONSTRATION MODELS, EXPERIMENTS PERTAINING TO SOME OF THE FUNDAMENTAL AND APPLIED METEOROLOGICAL CONCEPTS, AND INSTRUCTIONS FOR MAKING SIMPLE WEATHER OBSERVATIONS. THE CRITERIA FOR SELECTION OF TOPICS WERE EASE AND COST OF CONSTRUCTING APPARATUS AS WELL…

Gives some ideas for studying and growing crystals in the classroom and home as well as some background information to help integrate these ideas into an existing science curriculum. Discusses three activities including common household materials and laboratory procedures. (CW)

Describes a technique of impregnating small amounts of sandy sediment in a quick curing resin for microscopic examination. Details the preparation of materials. Suggests laboratory exercises based on this preparation. (CW)

Gill-breathing freshwater snails (Family "Pleuroceridae") are ecologically important, abundant in many streams in the United States, and easy to collect and maintain under classroom conditions. These snails can be used in classroom tests to demonstrate effects of pollutants on aquatic organisms. In more advanced classes, students can cage the…

Sedimentary patterns and hydraulic effects can be studies in model streams which are not to scale. The "Western River" is such a model which is being used effectively at Western Carolina College. Construction of the model, student exercises, and observations made when using the model are discussed. (Author/JN)

Presents information and data on an experiment designed to test whether different atmosphere compositions are affected by light and temperature during both cooling and heating. Although flawed, the experiment should help students appreciate the difficulties that researchers face when trying to find evidence of global warming. (PR)

Describes the "Physics by Inquiry" course that is designed to address student misconceptions. Explains how the course was taught at the University of North Carolina at Greensboro for teachers and how it was taught at Ohio State University for elementary-education majors. Concludes the course is exportable to many different environments…
