This article aims to implement an engineering design-based STEM activity for young children and evaluate the implementation process of the activity, along with providing some revision ideas. The activity was held as a 90-minute weekend workshop with the participation of six children aged four to seven. Data were collected through digital…

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…

This article introduces a flexible and easy-to-implement open-ended scientific inquiry activity called the Paper Towels Challenge. After experimentally determining which of three unbranded paper towels is the most absorbent, students discuss their results and methods. The teacher facilitates the discussion of epistemological issues. This activity…

Ocean currents play an important role in regulating the Earth's climate by redistributing ocean heat around the planet. One important climate phenomenon that includes several large ocean currents is the Atlantic Meridional Overturning Circulation, which is the process of warm surface currents in the North Atlantic Ocean moving to the Arctic to…

English learner (EL) students face the challenge of learning a new language while simultaneously learning other subjects. Similarly, English as Second Language (ESL) teachers have the added responsibility of teaching academic language in STEM subjects to EL students, in addition to language teaching. This article explores how a participant…

A problem-based learning activity focusing on the human impact on the environment and the importance of sustainable development is presented. The activity revolves around a mysterious island where the civilization is on the blink of extinction, prompting students to investigate how human behavior, ecosystems, resources, and natural balance…

Learning STEM applications in the first years of education reinforce children's curiosity toward exploring the world around them, and form the basis for all scientific studies they will receive throughout their lives. The aim of this study is to implement the STEM activity on the subject of seasons to preschool students. In the spring semester of…

Regardless of the cost and long preparation time, tactile materials are increasingly being used in science and mathematics education for students with visual impairment. In this study, a hands-on tactile activity related to making magnets using a STEM educational approach for students with visual impairment are introduced.

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…

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…

The purpose of this paper is to integrate mathematical modeling and ecology by presenting an activity involving an authentic environmental problem, which is called "Pine Processionary Caterpillars Invasion." Adopting Mathematical Modeling and Education for Climate Action (EfCA) approaches, it was aimed to encourage pre-service teachers…

The Earth's oceans are home to a diverse array of life, from large marine mammals to microscopic organisms. Among the most important are the marine phytoplankton, which comprise the basis of marine food webs, and also produce a large percentage of the Earth's oxygen through photosynthesis. Although the vast majority of phytoplankton are essential…

The purpose of this article is to design and develop an Arduino-assisted robotic and coding activity in compliance with the 5E instructional model in order to help secondary school students improve their science achievement in the science course. The research was conducted with 5th grade students studying at a private secondary school in Turkey in…

Children are very curious about the world around them. You may find them peering at tadpoles in a pond, counting ants on a log, or wondering about the stars, the sun, and the moon. I have been asked many times: Is the moon really made of cheese? Do astronauts live on the moon? Why does the moon look different every time I look up? Introducing…

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…
