This paper describes a laboratory exercise used to address the ongoing need for nanotechnology-related, hands-on laboratory experiences for undergraduate students. Determination of the electrochemical behavior of student-fabricated silver nanogrids is reported. Students successfully used cyclic voltammetry to analyze silver nanogrids printed using…

A procedure for the study of structural differences and intermolecular attraction between ethanol and 1-butanol based in laboratory work is described. This study provides comparisons of data retrieved from both a determination of boiling point and gas chromatography traces for the mixture. The methodology reported here should provide instructors…

Protein synthesis, involving such abstract concepts as "DNA," "RNA," "transcription," and "translation," is one of many biological processes too small to be seen by the naked eye. This combination of scientific jargon and sub-microscopic elements can make biology seem overwhelming to any student--but…

We report here a method that utilizes the vapor pressure of HCl(g) above a concentrated HCl(aq) solution as an extremely simple and safe method to produce small amounts of HCl vapor in an IR gas cell. This vapor pressure approach can also be used to produce DCl(g) by introducing a few drops of concentrated DCl(aq) into the gas cell.

The different reactivities between 1°, 2°, and 3° butyl chlorides by the unimolecular nucleophilic substitution (S[subscript N]1) mechanism were easily observed at 60 °C by a solvolysis reaction in ethanol with ether formation. The hydrogen ion from the byproduct HCl reacted with an acid--base indicator such as methyl red to induce a color change.…

All educators want their classrooms to be inviting areas that support investigations. However, a common mistake is to fill learning spaces with items or objects that are set up by the teacher or are simply "for show." This type of setting, although it may create a comfortable space for students, fails to stimulate investigations and…

This article describes an inquiry science lesson that was sparked by a child's question. In this school a science specialist (author 1) team teaches science with the kindergarten class teacher (author 2) for 1 hour per week. The class teacher integrates science at other times during the week. To foster the kindergarteners' interest about a science…

This study describes a program that the University of Alabama at Birmingham (UAB) carried out in partnership with Birmingham City Schools (BCS) to test an educational intervention, i.e., Hands-On Physics (HOP), among 8th grade students in predominantly minority schools. It also evaluated teachers' demographics and educational backgrounds. The…

In this case study, we present opportunities science, technology, engineering, arts, and mathematics (STEAM) education provided to a sixth-grade class. We collected observational and interview data in a language arts and a science class over 1 year. We used the liberation social psychology (LSP) framework to understand students' discourses and…

The COVID-19 pandemic has created significant challenges for informal health science education, which traditionally involves face-to-face programming. We describe the adaptation of hands-on environmental health science kits for online and socially distanced informal education with diverse audiences. These hands-on science kits were traditionally…

The need for more sustainable practices is in high demand. Green chemistry discusses practices that would lead to less harmful chemical products ending up in the environment. Herein, we describe an outreach activity that introduces minority high school students to the topic of green chemistry. Three hands-on activities were done to illustrate a…

Inquiry-based laboratory activities, as a part of science curricula, have been advocated to increase students' learning outcomes and improve students' learning experiences, but students sometimes struggle with open-inquiry activities. This study aims to investigate students' perceptions of inquiry-based learning in a set of laboratory activities,…

Initial teacher education (ITE) providers prepare graduates to be effective classroom practitioners, but there is little contemporary research capturing what this preparation actually looks like for primary (elementary) science education in Australia. Drawing on a broader study, this paper reports on teacher educators' practices and perspectives…

This dissertation examines, in three studies, undergraduate student experiences in social aspects of online learning when conducting remote physics laboratories. The first quantitative, observational study examined introductory students' epistemological, socialization, and help seeking views (N=998). Parametric and nonparametric tests indicated no…

This is the story of how an enterprising high school student came to my lab one afternoon, asking if there were any way that he could gain "hands-on" lab experience by working with me. While I had some doubts about allowing him to work in an area with an expensive 150-mW focused laser beam, I eventually said yes. I was well aware that a…
