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…

Design activities can serve as a concrete experience to address the similarities and differences between science and engineering, and also demarcate engineering from tinkering. They can lay the foundation for concept development of targeted disciplinary ideas. Minor, but crucial, changes to classroom tinkering activities along with targeting and…

Existing research primarily examines the impact of structured, credit-bearing service learning in undergraduate chemistry, leaving the potential contributions of co-curricular service learning and its lasting influence on chemistry graduates underexplored. Therefore, this mixed-methods study aimed to assess the lasting impact of co-curricular…

A two-part workshop connecting environmental science topics and green chemistry principles for undergraduate students is described. Students first collect acorns and rusted metal for dye and mordant baths. After 2 weeks they are invited back to tie-dye cotton fabric using dye baths prepared from steeped acorns and modify these colors using mordant…

Children can see the Moon with the naked eye and often are curious about the Moon and other objects in the sky, like the Sun and the stars. However, there is sometimes disagreement in early childhood about whether studying space is appropriate for young children. This activities described in this article engaged children who had different learning…

In this research, it was aimed to examine the effects of interdisciplinary science activities on 5th grade students' creative problem-solving skills and 21st century skills. The study group consisted of 50 5th grade students, 26 girls and 24 boys, were studying at a public school in Ankara, Çankaya district in the 2018-2019 academic year. The…

LASAR (Learning about Science and Religion) has been exploring different opportunities to engage children with practical science enquiry to develop children's understanding of the nature of science and how they suppose science connects to 'big questions'. After-school club opportunities and classroom opportunities are presented.

Our aim in this paper is to describe an opportunity for physics students and faculty to learn about an environmental issue of much current interest: the quantification, or footprint analysis, of carbon dioxide (CO[subscript 2]) and reactive nitrogen emissions. These can originate from human activities such as energy use, food consumption, and…

Students often struggle to make interdisciplinary connections and cite a lack of opportunity to make such connections. To address this issue, we are developing activities aligned with the framework of three-dimensional learning that provide students with opportunities to make connections between chemistry concepts and biological phenomena. Here,…

We present herein a module of pigment synthesis experiments that could be adapted and implemented in a variety of curricular settings. At the conclusion of each of the past two spring terms at our high school, we offered a 4 day short course on the chemical synthesis of pigments used in art. As part of the course, our students synthesized four…

This article presents a series of activities that not only help learners discover the waggle dance--a behavior performed by scout bees to communicate the location of a flower patch--and its purpose but also introduce circuitry, engineering, and energy transfer using hands-on, inquiry-based strategies. These activities were conducted in a…

One way to develop a cross-curricular lesson is to select the most common mathematical formulas used in science and carefully develop and implement tasks that allow students to make connections between the mathematical representations and theoretical/physical science concepts. The slope-intercept formula, which is used to study relationships…

The worldwide scientific community has been promoting science communication from colleges and universities to schools, and different tools for communicating scientific discoveries have been created. Among this variety of tools, our choice fell on a storybook. The book, entitled "The Curious Case of Ants That Live in Galls," is directed…

The greenhouse effect poses a significant environmental challenge to humanity today. Research shows that many students lack adequate knowledge about this phenomenon. To address this issue, we have developed educational materials that utilize various instructional approaches to improve primary school students' understanding and attitudes toward the…

Integrated Science, Technology, Engineering, and Mathematics (STEM) education has gained popularity worldwide. With the twenty-first century's different economic, political, and societal needs, nations intend to train citizens as better problem solvers. The current integrated STEM movement has influenced science curriculum documents and science…
