This report summarizes the activities and findings of the external evaluation of the "Science: It's Elementary" (SIE) program during the period from July 2009 through June 2010. The SIE program is managed by ASSET Inc. and overseen by the Pennsylvania Department of Education (PDE). SIE is an initiative aimed at improving elementary…

National Aeronautics and Space Administration (NASA) Engineers at Marshall Space Flight Center, Dryden Flight Research Center, and their partners at other NASA centers and in private industry are currently developing X-33, a prototype to test technologies for the next generation of space transportation. This single-stage-to-orbit reusable launch…

In this article, the authors discuss a unique and challenging laboratory exercise called, the paint-stir-stick submarine, that keeps the students enthralled. The paint-stir-stick submarine fits beautifully with the National Science Education Standards Physical Science Content Standard B, and with the California state science standards for physical…

The near daily news reports on food-borne diseases caused by contaminated produce, dairy, or meats suggests to the public that the safety of the U.S. food supply is in jeopardy. These reports, as well as a general distrust in federal agencies due in part to mad cow disease and toxigenic forms of "E. coli" in ground beef, have resulted in an…

Have the winter doldrums left your students wistful for summer? Why not initiate a seashell classification activity to rekindle their interest in science and learning! Children love to handle and examine shells at any time of the year--with these favorite nature objects, you often can't get kids to stop talking and sharing their observations about…

This article describes the process of design and implementation of a hands-on unit on fractions in the sixth grade. The fraction unit, taught by a classroom teacher with the aid of a university professor, uses pattern blocks to help students develop conceptual understanding of fractions. Student misunderstandings and outcomes are presented, as…

The inertial balance is one device that can help students to quantify the quality of inertia--a body's resistance to a change in movement--in more generally understood terms of mass. In this hands-on activity, students use the inertial balance to develop a more quantitative idea of what mass means in an inertial sense. The activity also helps…

Engines, in their many forms and functions, have had a tremendous impact on society and the environment. It is hard for the contemporary student to fathom a world without trains, cars, trucks, powerboats, and airplanes. With the fascination, history, impacts, and importance of engines to modern society, it is only natural that engine technology…

Probability is an essential tool for understanding heredity and modern genetics, yet many students have difficulty with this topic due to the abstract and quantitative nature of the subject. To facilitate student learning of probability in genetics, we have developed a set of hands-on, cooperative activities that allow students to determine…

A simple and cost-effective experiment for the development and characterization of semiconductors using Uv-vis spectroscopy is described. The study shows that the optical properties of ZnO films can be easily modified by forming Zn[subscript 1-x] Co[subscript x]O solid solutions via spray pyrolysis.

The National Assessment of Educational Progress (NAEP), the only ongoing survey of students' educational progress, has become an important resource for obtaining information on what students know and can do. This document reports on the NAEP 1996 science assessment that continues the mandate to evaluate and report educational progress of students…

This packet of information was presented at the national forum to showcase energy education initiatives that provide hands-on learning opportunities for K-12 students. This packet contains organization names, contact names, and e-mail addresses for all the exhibitors that participated in the forum. A section of selected print and CD-ROM resources…

This paper presents the results of a study concerning the use of text in support of firsthand scientific inquiry instruction in the early elementary grades. A partial transcript of two teaching sessions in which an expert classroom teacher incorporated text into her inquiry instruction is investigated. The knowledge gained from these sessions…

Presents a science activity on the water cycle, evaporation, and condensation and describes how to build a water cycle terrarium. (YDS)

Presents an activity to simulate electrophoresis using everyday items. Uses adding machine paper to construct a set of DNA fingerprints that can be used to solve crime cases designed by students in any biology class. (JRH)
