Silver and its compounds have been widely used in experimental teaching, industrial production, and other fields. In these processes, a large amount of wastewater containing silver is usually produced, which might contribute to environmental pollution. Therefore, recycling silver from wastewater not only has good economic value but also meets the…

Colleges throughout the United States typically expect their students to take at least one course in the sciences to fulfill liberal studies curriculum requirements. For nonscience majors, the choice of science class can include introductory chemistry, introductory biology, and astronomy, among others. Based upon interactions both in and out of…

A flipped classroom describes a class where students complete readings and watch lectures outside of class, while in-class time is spent on activities to practice content learned. The implementation of a flipped classroom approach has been shown to increase student learning and student enjoyment of courses. This paper describes using the flipped…

In this paper, we present simple demonstrations aimed at explaining the fundamental principles of the photoacoustic effect. To display the audible phenomenon that occurs as laser radiation gets absorbed by ethene gas, an optical chopper was used to modulate the power of a continuous-wave laser whose beam was directed into a gas. The absorbed…

Hydrogel is an interesting topic in polymer chemistry, which is closely related to daily life and advanced technology. In this paper, we report an activity to deliver hydrogel chemistry into middle school classrooms by undergraduates as a bridge between professors and students. During the activity, undergraduates act as a bridge to receive…

Chemistry laboratory experiments are invaluable to students' acquisition of necessary synthetic, analytical, and instrumental skills during their undergraduate studies. However, the COVID-19 pandemic rendered face-to-face (f2f), in-person teaching laboratory experiences impossible from late 2019-2020 and forced educators to rapidly develop new…

Offering high school students' exposure to university level laboratory research encourages interest in science, develops critical thinking, and prepares the new generation for college and careers. In this study, we report on the development of an immersive 2-week summer camp with the aim of training high school students in cancer research.…

Chemistry is a vital and highly relevant field of science that is under-represented in science centers and museums. Amidst concerns that the public is ambivalent about the chemistry field, the "Explore Science: Let's Do Chemistry" project sought to understand how to design hands-on activities that could increase the feelings of interest,…

Science dissemination or popularization of science refers to the act of facilitating the understanding of research and works of scientific and/or technological origin among the general public. Science dissemination is a relevant issue in the realm of public policy. Considering that in Brazil, the university is responsible for most of the…

The current study describes preliminary findings from the Xavier University of Louisiana Mobile Outreach for Laboratory Enrichment (XULA-MOLE) project, which is a collaboration between Xavier University of Louisiana (XULA), a Historically Black and Catholic University, and participating 9th-12th grade classrooms in the central New Orleans area…

The American Chemical Society's Chemistry Festivals, or "Festivales de Química," are community events where chemistry professionals, professors, teachers, and students use hands-on activities to engage the public and demonstrate how chemistry appears in our everyday life. The Chemistry Festival Organizers received training from the ACS,…

Reported herein is the design, implementation, and evaluation of a full-day outreach program for high school girls that focuses entirely on sugar-related activities. The program, which we ran in February 2016 and February 2017, included multiple hands-on sugar-based experiments to increase the participants' interest in and enthusiasm for science.…

Introduction to Research is a 4-credit elective course designed for first-year undergraduate students who have a strong interest in the chemical sciences and scientific research. The rich yet accessible field of gold nanoparticles was the theme connecting a multifaceted teaching/learning experience. In the first unit, students were introduced to…

University of Virginia, like many other universities, has developed a chemistry outreach program (called Chemistry Learning through Experimentation, Awareness, and Demonstration; i.e., Chemistry LEAD) that visits K-5 schools and teaches inquiry-based chemistry lessons in order to engage local students with science. Chemistry LEAD is graduate…

In the past 20 years, science education in schools has increasingly been supported by extracurricular learning opportunities. From the point of view of pupils and teachers, student laboratories make meaningful contributions to complement the teaching of science. Studies have shown that participation in student laboratories has increased students'…
