Describes a variation of typical introductory chemistry stoichiometry experiments in which the reaction is run in a modified 20-ounce plastic soda bottle. (WRM)

Reports on a technique for illustrating the dependence of the rate of reaction on the concentration of the reactants and for determining the order of reaction with respect to each reactant, the overall order of reaction, the reaction rate constant, and the half-life. (WRM)

Discusses historical and current federal role in educational research and development; asserts need for improved quality and expanded scope of research from Department of Education's Office of Educational Research and Improvement. Describes shortcomings and desired changes; advocates creation of independent R&D agency and open competition for…

Shows how schools are establishing environmental-management systems to help them comply with stricter federal regulations. Topics addressed include hazardous waste management and use of third-party audits to prepare for Environmental Protection Agency inspections. Environmental guidelines for laboratories and special concerns confronting science…

Presents the floral foam activity which explores the relationship between volume and mass. Focuses on helping students to enhance their critical thinking skills. (YDS)

This study investigated safety in Texas secondary school science laboratory, classroom, and field settings. The Texas Education Agency (TEA) drew a random representative sample consisting of 199 secondary public schools in Texas. Eighty-one teachers completed Incident/Accident Reports. The reports were optional, anonymous, and open-ended; thus,…

School-based health centers (SBHCs) often are located in high-need schools and communities. Dental service is frequently an addition to existing comprehensive services, functioning in a variety of models, configurations, and locations. SBHCs are indicated when parents have limited financial resources or inadequate health insurance, limiting…

In this article, I explore some of the epistemological, technical, and ethical challenges in doing research on instructed second language (L2) learning in Canadian school settings. I examine these challenges from the viewpoint of classroom research that has been influenced by cognitive-interactionist theories of learning. This includes my own…

This qualitative study examined Chinese international laboratory-based research students' experiences of supervision during the first six to eighteen months of their candidature in Singapore. The experiences of marginalization in student/supervisory relationship identified in the study, particularly in the first six months, may very largely be…

Children love observing seeds change as they germinate and grow into tall healthy plants, but how can teachers make investigating plants an exciting and immediate event? Microscopy might just be the answer. Although most students have seen flowers, not many have looked closely at their various structures or seen their colorful designs only…

The author's favorite way to start the new school year is to perform a science demo for students. At the beginning of the period, he discusses the importance of making accurate observations. He tells them that he will perform a short demonstration that they are to carefully watch and then record their observations. They each have a sheet of paper…

For middle school students, writing a formal lab report can be challenging. For middle level teachers, reading students lab reports can be overwhelming. After grading report after report with incomplete procedures, incorrect graphs, and missing conclusions, the author's frustration level was at an all-time high. Ready to try anything, he thought,…

We use identity as a multidimensional lens to explore ways in which beginning teachers saw themselves as scientists and as science teachers during and after 10-week summer apprenticeships at a science lab. Data included four interviews with each teacher, three during the apprenticeship and one after the first year of teaching. Two themes emerged…

Although the literature on both academic dishonesty and scientific misconduct is extensive, research on academic dishonesty has focused on quizzes, exams, and papers, with the virtual exclusion of the classroom laboratory. This study examined the distinctions undergraduate chemistry majors made between academic dishonesty in the classroom…

In this article, the author presents the "Praise Acres Project," which was initiated from a letter written by a local resident. The resident wrote about an idea to develop a wetlands and outdoor lab facility on his property for students. Thus, a plan was conceived that would not only benefit the owner, but also enhance high school science…
