Purpose: Hands-on training in tissue engineering is often associated with specialized labs and expensive equipment, such as CO[subscript 2] incubators. To minimize the use of costly commercial incubators and provide a more vivid engineering experience in a biology lab, we present a hands-on project that introduces medium to large groups of…

1000 Future Scientists (1000FSc) is a university extension project developed at the Department of Chemistry in Federal University of Minas Gerais (UFMG). Conducted by the Higher Education Administrative Technicians and Professors, it presents the university to the community by proposing an engaging experience for elementary and high school…

A laboratory experiment was developed to enable students to investigate the use of smart hydrogels for potential application in targeted drug delivery. This is challenging for students to explore practically because of the extremely high risks of handling cross-linking agents such as glutaraldehyde. Genipin is a safe and green alternative that has…

A chemical engineering PhD student from Purdue University completed an internship at The Dow Chemical Company, evaluating the effect of scale on the hydrodynamics of a trickle bed reactor. A unique aspect of this work was that it arose from an ongoing collaboration, so that the project was within the scope of the graduate student's thesis. This…

We designed a "3D Printing Technology Science Project" as part of a science methods course to engage preservice teachers (N = 41) in a 3D printing project that they could implement with their future elementary school students. The goal was to introduce prospective teachers to engineering design and technology application ideas and…

There is an increasing focus across all educational sectors to ensure that learning objectives are aligned with learning activities and assessments. An attractive approach previously published is that of curriculum alignment projects. This paper discusses the use of the fun and famous "Elephant's Toothpaste" experiment as a customizable…

Problem Statement: Research studies indicate that teachers with negative attitudes toward science tend to use didactic approaches rather than approaches based on students' active participation. However, the reviews of the national academic literature in Turkey located a few research studies on the relationship between playful science experiences…

Incorporating business skills such as problem-solving, public presentations, collaboration, and self-direction into STEM (science, technology, engineering and mathematics) subjects is an excellent way to build students' enthusiasm for these disciplines. When educators add workplace internships to the learning experience, they are well on their way…

Students should enjoy their laboratory classes and for this purpose a project-based activity is added to a conventional physical chemistry laboratory. Students were given project work instead of conventional experiment and then they had to make progress in the project according to instructions and then carry out experiments related to the project.

This paper describes a set of simple experiments with a very low cost using a notebook as a measuring instrument without external hardware. The major purpose is to provide demonstration experiments for schools with very low budgets. (Contains 6 figures.)

The term "restriction endonuclease mapping" covers a number of related techniques used to identify specific restriction enzyme recognition sites on small DNA molecules. A method for restriction endonuclease mapping of a 1,000-basepair (bp)-long DNA molecule is described in the fictitious experiment of this test. The most important fact needed to…

This open-ended practical series titled "Molecular Identification of Unknown Food Bacteria" which extended over a 6-week period was designed with the aims of giving students an opportunity to gain an understanding of naturally occurring food bacteria and skills in contemporary molecular methods using real food samples. The students first isolated…

A pedagogical experiment is described to examine the physical absorption of gases, in this case carbon dioxide, in a hollow fiber membrane contactor (HFMC) where the absorption concentration profile can be followed by a color change. The HFMC is used to teach important concepts and can be used in interesting applications for students, such as…

In delivering chemistry courses by distance, a key challenge is to offer the learner an authentic and meaningful laboratory experience that still provides the rigour required to continue on in science. To satisfy this need, two distance general chemistry laboratory courses appropriate for Bachelor of Science (B.Sc.) students, including chemistry…

We describe an investigative laboratory module designed to give college undergraduates strong practical and theoretical experience with recombinant DNA methods within 3 weeks. After deducing restriction enzyme maps for two different plasmids, students ligate the plasmids together in the same reaction, transform "E. coli" with this mixture of…
