In this article, simple models of optical computing circuits (1 x 4 demultiplexer (DEMUX), 4 x 1 multiplexer (MUX), Boolean logic, and half-adder (HA)) are shown with mechanically controlled plane mirrors. Photographs of the proposed computational circuits are also shown. It is very useful for the school student to understand optical logic and…

Below the surface of the ocean, currents, eddies, and other physical processes redistribute energy and biologically important elements. Measuring this transport can be challenging, and scientists must address a wide spectrum of oceanographic and engineering concepts when designing instruments to observe these processes. In this activity,…

Activities that engage high school students in visualizing chemical phenomena can help them develop representational competence to think about and communicate their understanding of these phenomena. This paper presents a collaborative learning activity that can engage precollege students in designing a poster that describes four different types of…

During the unprecedented and rapid spread of the coronavirus disease-2019 (COVID-19) around the World, students have been concerned about the disease as much as the rest of the global community. As a real-world problem, the COVID-19 pandemic with many different debatable facets has social and scientific components, impacts society, and shows…

Over the past several decades it has become increasingly important to understand nature of science (NOS) for scientific literacy in science education. Science education researchers have suggested using socio-scientific issues to create a context for that purpose. The present fast-moving coronavirus or COVID-19 pandemic as a socio-scientific issue…

This paper describes the integration of geographic information system (GIS) technology in a high school environmental science classroom, specifically examining the impact of GIS technology on student engagement, critical thinking, and interdisciplinary learning for Education for Sustainability (EfS). This environmental science classroom utilized…

Virtual water is the amount of water that we ignore in water consumption and is considerably higher than the visible water we see in daily uses. Realizing the water spent in the production processes of objects can cause us to change our consumption habits. In 1979, Joseph Cornell presented a four-step framework called Learning Flow to move nature…

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 +…

Molecular processes are highly complex, and are frequently difficult for high school and college students to comprehend. Because of the importance of visualization in learning, along with formative assessment of student understanding, utilization of 3D modeling software aids both educators and students alike. The activity described below required…

The magic flask, which is a kind of black box activity, builds an environment for science teachers to discuss nature of science in a formal or/and informal learning environment in the context of the history of science through an explicit-reflective approach. In the activity, the nature of science (NOS) aspects are explicitly addressed and…

The ecological footprint concept is important in order to evaluate the human impact on the environment and propose sustainable solutions in our life. By calculating ecological footprint, people could analyze the impact of their lifestyle on the natural environment. The purpose of this study is to share an ecological footprint education module for…
