Fully online courses and degree programs are popular with students today. It is important that these courses provide the same rigor and value of a traditional learning experience in a face-to-face classroom in order to ensure mastery of concepts and learning objectives. Online classes typically have suffered due to a lack of hands-on experiences…

What follows is a description of the procedure for and results of a simple experiment on the formation of impact craters designed for the laboratory portions of lower mathematical-level general education science courses such as conceptual physics or descriptive astronomy. The experiment provides necessary experience with data collection and…

This laboratory introduces students to laser-induced breakdown spectroscopy (LIBS) for the analysis of metals in soil and rock samples. LIBS employs a laser-initiated spark to induce electronic excitation of metal atoms. Ensuing atomic emission allows for qualitative and semiquantitative analysis. The students use LIBS to analyze a series of…

The ancient Eratosthenes experiment concerning the earth's circumference offers the opportunity of an inquiry-based revival in today's science classrooms: A multinational European science education initiative (acronym: OSR) introduced this experiment as a hands-on basis to extract the required variables and to exchange results with classroom peers…

I describe how to obtain a rather good experimental determination of the eccentricity of the Earth's orbit, as well as the obliquity of the Earth's rotation axis, by measuring, over the course of a year, the elevation of the Sun as a function of time during a day. With a very simple "instrument" consisting of an elementary sundial, first-year…

This article introduces a set of distance education astronomy laboratory exercises for use by college students and instructors and discusses first usage results. This General Astronomy Education Source exercise set contains eight two-week projects designed to guide students through both core content and mathematical applications of general…

This article describes an activity done by eighth grade students using data that was gathered from sun-shadow observations. (Contains 5 figures.)

This book provides opportunities for engaging students in scientific investigations, offering a hands-on approach that encourages students to understand science concepts, gives them ways to apply the concepts, and introduces and reinforces the skills they need to become independent investigators. The basic outline and objectives of each section of…

The purpose of this guide is to highlight some broad areas in which teachers and other adults have exceptional opportunities to encourage and enjoy teaching children science. Each area in the book provides some hands-on ideas for projects as well as an annotated list of readily available resources that might prove helpful on the topic at hand. The…

The purpose of the Toys in Space project was to create new ways for children to discover the joy and excitement of science and technology in the world around us. This book describes how familiar toys behave in the space environment where the downward pull of gravity is absent, and clearly documents those principles of physics that explain why the…

This book helps teachers fulfill curriculum requirements by building both science content and process skills through hands-on exploration. Ten broad subject areas are covered: (1) Discovering Science, (2) Matter and Energy, (3) Humans, (4) The Environment, (5) Rocks, (6) Plants, (7) Living Creatures, (8) Weather, (9) The Heavens, and (10) Applying…
