The theoretical basis of reactive oxygen species and their impact on health issues are relatively easy to understand by biomedical students. The detection of reactive oxygen species requires expensive equipment, the procedures are time consuming and costly, and the results are hard to interpret. Moreover, cause-and-effect relationships in the…

Corcoran, K. Blake; Rood, Brian E.; Trogden, Bridget G. – Journal of Chemical Education, 2011
This project involved developing a method to remediate large quantities of aqueous waste from a general chemistry laboratory experiment. Aqueous Ni(II) waste from a general chemistry laboratory experiment was converted into solid nickel hydroxide hydrate with a substantial decrease in waste volume. The remediation method was developed for a…

Grady, Julie R.; Madden, Andrew S. – Science Activities: Classroom Projects and Curriculum Ideas, 2010
Investigations that integrate concepts from geological sciences with biology and chemistry are rare. The authors present an investigation that introduces high school students to microbe-mineral interactions by tying together anaerobic respiration, reduction reactions, metal ion solubility, and groundwater pollution. During the investigation,…

Timerman, Anthony P.; Fenrick, Angela M.; Zamis, Thomas M. – Journal of Chemical Education, 2009
A sequence of exercises for the isolation and characterization of invertase (E.C. 3.1.2.26) from baker's yeast obtained from a local grocery store is outlined. Because the enzyme is colorless, the use of colored markers and the sequence of purification steps are designed to "visualize" the process by which a colorless protein is selectively…

Montagna, Erik; Guerreiro, Juliano R.; Torres, Bayardo B. – Biochemistry and Molecular Biology Education, 2010
The understanding of complex physiological processes requires information from many different areas of knowledge. To meet this interdisciplinary scenario, the ability of integrating and articulating information is demanded. The difficulty of such approach arises because, more often than not, information is fragmented through under graduation…

Dancho, Kelly A.; Thompson, Rachel H.; Rhoades, Melissa M. – Journal of Applied Behavior Analysis, 2008
We evaluated the effectiveness of group safety training and in situ feedback and response interruption to teach preschool children to avoid consuming potentially hazardous substances. Three children ingested ambiguous substances during a baited baseline assessment condition and continued to ingest these substances following group safety training.…

McDonald, Chriss E. – Journal of Chemical Education, 2009
Virstatin, an "N"-butanoic acid substituted naphthalimide, inhibits the ability of "Vibrio cholerae" to cause disease. A three-week experiment involving synthesis, purification, and spectral characterization of this compound is described. This experiment is appropriate for organic chemistry. It has been performed with three lab sections of about…

Hampton, Elaine; Wallace, Mary Ann; Lee, Wen-Yee – Science Scope, 2009
In this lesson, a ready-to-teach cooperative reading activity, students learn about the effects of plastics in our environment, specifically that certain petrochemicals act as artificial estrogens and impact hormonal activities. Much of the content in this lesson was synthesized from recent medical research about the impact of xenoestrogens and…

Katz, Civia A.; Calzola, Zachary J.; Mbindyo, Jeremiah K. N. – Journal of Chemical Education, 2008
A microscale laboratory experiment to investigate the formation and utility of microemulsions is described. Microemulsions are technologically important fluids that can reduce the use of toxic organic solvents. In the experiment, students prepare a microemulsion and compare the solubility of sudan III dye in the microemulsion and in dodecane. They…

Mascarenhas, Cheryl M. – Journal of Chemical Education, 2008
In this experiment, organic chemistry students perform reactions between three naphthyl acetate derivatives and the diazonium salt Fast-Red TR, under basic conditions. The three naphthyl acetate derivatives used in this study are 2-naphthyl acetate (1a), 6-bromo-2-naphthyl acetate (1b) and 1,6-dibromo-2-naphthyl acetate (1c). The two-step, one-pot…

More than 53 million children and 6 million adults in the United States spend their days in elementary and secondary schools. Reducing environmental risks inside these buildings is critical to maintaining the public health. Almost all of New England's children will spend a large portion of their childhood in school. To help children stay healthy,…
