This work describes an alternative approach for introducing the concept of pH in high school. We develop an experimental protocol to demonstrate in classroom as pH affects the life of microorganisms. At the same time, we constructed low-cost equipment and a homemade culture media using ordinary products, which they are easily found by the teachers…

We present an example of a novel, model-based approach to instruction in which learners constructed a representation of a specific phenomenon, evaluated their representation, and then revised it, via an abstraction process, to construct a model. The example took place in high school in the context of solution chemistry. The aim of the instruction…

The study presents an integrated STEM activity involving a 3D printer and entrepreneurial problem solving. The study was conducted with 20 high school students who worked in groups to make their own unique kolonya (a traditional Turkish sanitizer), similar to eau de Cologne. They then designed kolonya bottles using TinkerCad before producing them…

Many students consume energy drinks without knowing or thinking about the adverse side effects. The purpose of this article is to share student procedures and results after testing the effects of a popular energy drink, Red Bull, on Dugesia Dorotocephala planarians (flatworms). Planarians are animals with neurotransmitters systems that are similar…

Recent reforms have introduced integrated science, technology, engineering, and math education (STEM) that has highlighted an interdisciplinary approach to train students as better problem solvers. In addition to STEM disciplines, art, language, and other disciplines integration are also stressed (STEM+). In this paper, a STEM+ (STEM + art +…
