During the 1994-95 school year, the Eisenhower Regional Consortium for Mathematics and Science Education at Appalachia Educational Laboratory (AEL) conducted the Scope It Out project to provide training and technical assistance to educators in using the microscope as a learning tool in a standards-based curriculum. This publication is a…

For various reasons, students do not have access to laboratory facilities and yet need courses in the laboratory sciences such as chemistry. This paper describes "Outreach Chemistry," a course developed to provide a chemistry laboratory experience for students attending schools that lack science laboratories. Designed for off-campus students whose…

This book for high school students presents 20 different science fair projects that provide an opportunity to learn how plants are affected by natural and man-made influences on their environments. Many experiments in the book were adapted from original International Science and Engineering Fair projects. Each project includes in-depth background…

Sources to assist junior and senior high school students and teachers in planning, preparing, and executing science fair projects in the biological science are cited here, as well as a few books with experiments suitable for elementary grade students. (AA)

Young children in Australia enter early childhood education settings eager to make sense of the world that surrounds them. Their interest in every day experiences is evident in the range of questions asked, many of which are scientific in nature. Intended as a resource for adults working with 4-to 8-year-old children, this booklet provides an…

Two laboratory investigations are described: (1) staining chromosomes in root tips and (2) demonstrating pollen tube growth. (LS)

Describes an undergraduate chemistry experiment in which the concentration of chloride, fluoride, or bromide ions can be quantitatively determined by titrating with mercury (II) ions. (MLH)

Provides a technique for the determination of the mass of a large, movable object. (CP)

Describes a group of chemistry experiments designed to convey to students the real and measurable nature of certain mathematical concepts. (BR)

Describes a demonstration with mothballs that simulates the ballast mechanism of a fish air bladder. (BR)

One way to motivate students' interest in physics is to teach it in the context of medicine. Optics, for example, can be taught with examples from the eye. For many years simple optics of lenses has been taught using a model of the eye. However, recent advances in using lasers for ophthalmological (ocular) examinations can be used to increase…

Traditionally, the Doppler effect for sound is introduced in high school and college physics courses. Students calculate the perceived frequency for several scenarios relating a stationary or moving observer and a stationary or moving sound source. These calculations assume a constant velocity of the observer and/or source. Although seldom…

A reactor to convert waste rubber tires to useful products such as CO and H2, was investigated in a university undergraduate design project. The student worked individually with mentorship from a faculty professor who aided the student with professional critique. The student was able to research the background of the field and conceive of a novel…

A low-cost tensile testing machine was built for testing polymeric films. This apparatus also allows for tear-strength and flexural tests. The experimental results, obtained from common-use materials, selected by the students, such as plastic bags, illustrate important aspects of the mechanical behavior of polymeric materials. Some of the tests…
