Virtual laboratories are transformative tools in science education, yet comprehensive reviews of their prospects are limited. This study addresses this gap through a bibliometric analysis of 218 articles published between 2013 and 2023. Key findings included: (1) research has evolved from initial exploration to rapid expansion; (2) virtual labs…

The paper explores the effectiveness of hands-on learning (HOL) as a student-centered model to train first year chemical engineering undergraduates. The pedagogical design of the course uses laboratory sessions, lectures, reflection sessions, projects, and assessments to achieve the course learning outcomes. The adopted assessment methodology…

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…

Describes how to perform the Meselson-Stahl experiment using Lego building blocks. Demonstrates how the products of DNA replication pass on to new generations of cells. (YDS)

Incorporating inquiry-based learning in the college-level introductory biology laboratory is challenging because the labs serve the dual purpose of providing a hands-on opportunity to explore content while also emphasizing the development of scientific process skills. Time limitations and variations in student preparedness for college further…

Explains a laboratory activity in which students study the effects of balanced and unbalanced nutrition on individuals' health by examining simulated urine samples. Uses a journal writing approach and includes laboratory instructions. (YDS)
