Prior to the COVID-19 pandemic, occupational therapy students at one university received all orthosis fabrication education through an in-person laboratory-based environment supported by clinicians and instructional videos. Due to the pandemic restrictions, orthosis fabrication labs for occupational therapy students were transitioned to a hybrid…

Upper-division undergraduate students are introduced to polymer processing using material extrusion fused filament fabrication 3D printing to make poly(lactic acid) (PLA) mechanical testing specimens. Computer aided design and slicing software packages are used to demonstrate the process of preparing 3D computer models for printing. Following the…

A laboratory experiment for the determination of the cross-linking density of silicone elastomers is described on the basis of swelling experiments and mechanical tests. In the experiment, the macroscopic swelling and mechanical behaviors of the elastomers were discussed as a function of the cross-linking density, which can be easily controlled by…

This paper introduces hands-on curricular modules integrated with research in atmospheric ice nucleation, which is an important phenomenon potentially influencing global climate change. The primary goal of this work is to promote meaningful laboratory exercises to enhance the competence of students in the fields of science, technology,…

Motivational hands-on workshops for grade-school level future scientists are needed to inspire young and receptive minds. Described here is an educational event, titled "Inspiring Future Rocket Chemists", with hands-on laboratory exercises demonstrating the fundamentals of rocket flight and live chemistry demonstrations illustrating the…

Written examinations for laboratory courses fall short in testing students' technical skills, problem-solving abilities, and execution of experimental design. This has led to practical examinations growing in popularity, but examples for senior-level students remain scarce. Senior organic chemistry students are gearing toward independence to…

Level 3 characteristics are increasingly important for fingerprint identification, particularly when the fingerprints are problematic and lack level 2 details. In practice, no reliable visualization methods for level 3 features are transferred into a course for the general public, forensic students, or investigators. Our group has reported the…

Computational chemistry instructional activities are often based around students running chemical simulations via a graphical user interface (GUI). GUI-based activities offer many advantages, as they enable students to run chemical simulations with a few mouse clicks. Although these activities are excellent for introducing students to the…

Electrophoresis is integral to analytical and biochemistry experiences in undergraduate education; however, fundamental principles of the method are often taught in upper-level laboratories through hands-on experiences. A laboratory activity is reported that teaches the concepts of electrophoretic mobility and electroosmotic flow. A single…

When teaching undergraduate biology courses, developing engaging activities which allow students to learn using a hands-on pedagogy can provide impactful learning moments for students. This activity helps students make connections between lecture content on environmental issues, e.g., the use of microplastics (MPs) and their own day-to-day…

The purpose of the present study was to investigate teachers' implementation practices and their perceived impacts and attitudes towards the use of KiwiCo learning crates with respect to student motivation, interest in STEAM, and development of 21st century learning skills. This case study utilized a mixed methods research design that administered…

Enzyme-Linked Immunosorbent Assay (ELISA) is a versatile and widely used technique to detect and quantify small molecules in various clinical and analytical applications. It is also an effective tool for demonstrating the specificity between antibody and antigen to students across diverse disciplines. However, undergraduate laboratories often face…

A simple apparatus consisting of a plastic syringe coupled with a U-tube has been constructed. This setup is filled with water to trap air in one arm of the U-tube. A change in the volume of the enclosed air causes a change in its pressure that is indicated by the difference in the water levels. Boyle's law is shown by a linear relation between…

The Life Sciences Learning Center (LSLC) is a hands-on science outreach center located at the University of Rochester's School of Medicine and Dentistry (UR-SMD) in Rochester, New York. The LSLC provides hands-on, case-based learning to boost science literacy and increase enthusiasm toward science learning. The LSLC offers on-site and in-school…

Biocompatible and biodegradable block copolymers composed of poly(ethylene glycol) (PEG) and aliphatic polyester are a class of promising biomaterials. Herein, a teaching experiment was designed to furnish undergraduates with a reliable method to synthesize an amphiphilic poly([epsilon]-caprolactone)-PEG-poly([epsilon]-caprolactone) (PCL-PEG-PCL)…
