This paper describes an inquiry-based integrated laboratory project for green synthesis, characterization, and applications of silver and gold nanoparticles. In this project, students were able to choose their choice of plant extract as reducing and stabilizing agents, and the students also designed their own experiments. This course gave the…

A multioutcome, guided inquiry-based liquid--liquid extraction (LLE) experiment has been designed for introductory organic chemistry. Multiple outcomes were established by identifying a series of red and blue dyes that are (1) soluble in organic solvent, (2) soluble in aqueous solution, or (3) soluble in either the organic or aqueous layers by…

Background: Native Americans are underrepresented in science, technology, engineering, and mathematics (STEM). We investigated whether having to violate cultural taboos might be a factor in the decisions of some Native Americans not to pursue STEM degrees. Many STEM faculty likely know very little about Native Americans' historical experiences…

Describes eight experiments involving the use of common consumer products that could be incorporated into quantitative and instrumental analysis laboratories. Discusses these activities in terms of illustration of principles, awareness, and critical thinking. (CW)

Demonstrates how to promote the transference of concepts and principles developed in other curricula to enhance a student's subject matter mastery in soil classification. Describes course format, critical thinking techniques, and a course evaluation. A conclusion and references are included. (Author/RT)

This document contains a cross-curricular cooperative learning experience that is designed to give high school students career and technical educational experiences in the areas of forensic sciences and criminalistics by doing the forensic work to "solve" a fictitious murder. The activities included in the cooperative learning experience…
