Louisiana Tech University has an integrated science curriculum for its mathematics, chemistry, physics, computer science, biology-research track and secondary mathematics and science education majors. The curriculum focuses on the calculus sequence and introductory labs in biology, physics, and chemistry. In the introductory biology laboratory…

A guided-inquiry exercise conducted in both the lecture and laboratory components of a college introductory chemistry course for non-science majors is described. The exercise gave students the opportunity to independently determine the relationship between the temperature of water in an aluminum soda can and the intensity of implosion upon placing…

There is often a particular void in the education of deaf and hard-of-hearing students who intend to become competent working laboratory technicians. Inasmuch as certain basic professional skills ("soft skills," in this case) are not generally taught in traditional science courses, a new curriculum has been developed in order to enforce…

This textbook integrates chemistry and art with hands-on activities and fascinating demonstrations that enable students to see and understand how the science of chemistry is involved in the creation of art. It investigates such topics as color integrated with electromagnetic radiation, atoms, and ions; paints integrated with classes of matter,…

More than 90% of vascular plants in terrestrial ecosystems form symbiotic root-fungal associations known as mycorrhiza; in Mediterranean biomes all known mycorrhizal types co-exist. However, the understanding of mycorrhizal diversity and structure and their ecophysiological impact in soil productivity and conservation has been shown to be very…

The electrical properties of polyaniline changes by orders of magnitude upon exposure to analytes such as acids or bases, making it a useful material for detection of these analytes in the gas phase. The objectives of this lab are to synthesize different diameter polyaniline nanofibers and compare them as sensor materials. In this experiment…

The Bureau of Labor Statistics (United States Department of Labor, Bureau of Labor Statistics [BLS], n.d.) has shown that workers involved in accidents have little, if any, instruction on the equipment they were using while injured. Keep in mind that instruction on the safe operation of a piece of equipment may take place early in the school year,…

Choosing what eye and face protection to provide for the high school science laboratory is often a challenge. Science teachers and school administrators may not fully understand the relevant safety regulations and standards or be able to correctly identify the various types of eye protection devices. Although some schools have received training…

An alternative method for the preparation of Pasteur pipet chromatography columns is presented that allows the column to be filled with solvent without bubbles and allows greater control of fluid flow while the materials to be separated are added. Students are required to wear gloves and goggles and caution should be used while handling glass…

Provides a brief sketch of this safety act, put into effect in Great Britain in April, 1975. (MLH)

Guidelines to aid teachers in selecting the correct eye protective device for students who are engaged in various laboratory activities. (GR)

Argues that as well as obtaining a subject's informed consent a researcher is ethically obliged to furnish financial protection to research subjects. Discusses possible methods of insurance. (EB)

This guide gives elementary school teachers suggestions for providing a safe environment for their students and covers general safety concerns in the science classroom. Information is printed in a flip chart format for easy reference. Safety areas covered include: (1) In Case of Accident; (2) Eye Protection; (3) Plants in the Classroom; (4) First…
