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,…

The present study aimed to develop, introduce, and conduct an activity for the integration of augmented reality to the jigsaw IV technique in a planned and systematic manner. The activity developed for secondary school students is related to the "Pure Substances" subject which it is included in the "Particulate structure of…

This integrated STEM activity on the design of a vertical farming system has biology as the lead discipline and relates to the concept of photosynthesis. Students investigated the optimal design of vertical farms that will deliver appropriate amounts of water, sunlight and carbon dioxide to plants such that there will be optimal yield. Through…

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…

School science is often very different from "real world" science. One important difference, and possibly the main one, is that in school science the relationships between variables have often been sanitized -- essentially "cleaned up" -- so that there is very little (and often no) variation in the data from the relationship…

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…

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…

Students come to class with little understanding about torque, angular velocity, and angular acceleration despite the fact that these physical science concepts are frequently observed. For example, torque occurs when car and bicycle tires rotate, the movement of fishing pole when hooking a fish, and when a person uses a hammer to drive in a nail.…

Understanding the nature of science has long been a focus of science education reform efforts, including the Next Generation of Science Standards. Students' views about the process of how scientific knowledge is acquired has been shown to affect their ability to learn scientific concepts. Integrating the nature of science into science lesson plans…

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 use of creativity in science practices is many times lost on secondary students. Creativity is seen as something central to the arts and humanities, but tangential at best in the sciences. However, an examination of many great scientific discoveries and the work of everyday contemporary scientists shows the depth and breadth of the use of…
