Genotyping real alleles in real people is an excellent way to connect abstract genetics concepts to human variation in the classroom; however, these activities can inadvertently promote misconceptions of the power of genetics to determine individual and group traits. By analyzing our own and others' experiences of genotyping activities in the…

Electricity has shaped modern civilization in a way few other discoveries have. Nonetheless, few students successfully develop a basic understanding of voltage, current, and resistance or their mutual relationship in simple DC circuits. Despite teachers' best efforts in the classroom, so-called "alternative conceptions" often prevail…

Computers and computer algorithms have contributed to important scientific advances by allowing scientists and engineers to create and use sophisticated models to explain and predict phenomena. Yet, of the eight "Next Generation Science Standards" ("NGSS") science and engineering practices, computational thinking may be the…

Especially within the light of the current loss of biodiversity, we want our students to gain a better understanding of the issues at stake in order to take action and support plants and their pollinators. Many educational approaches focus on honeybees, disregarding the vast diversity in the context of pollination systems and the complex…

Recent work in science education has emphasized the importance of the conceptual, social, and epistemic dimensions in science learning. But what about the material dimension--the actual physical materials that students use? The way their characteristics and affordances limit or determine instruction has thus far not been as thoroughly explored.…

Corrosion of metal, especially iron, is a natural electrochemical process that costs billions of dollars every year. Educating college and precollege students, our future STEM professionals, about the chemistry that governs corrosion and its prevention strategies is of paramount importance. In this manuscript, we share a few simple iron…

This article introduces a range of ways to engage students in microscopy, from investigating water droplet lenses to using low-cost, highly adaptable instruments that can be extremely effective inside and outside the classroom.

In this article, the authors discuss how the COVID-19 pandemic completely changed the way one project communicated with children, parents, and teachers. The authors describe how they developed Science Gateways out of the need to handle the limitations of the Science Open Doors program that was developed prior to COVID-19. Science Gateways serves…

Large data sets invite students to engage in scientific practices such as question asking, identifying correlations, using visualizations, and practicing data literacy in an authentic context. However, authentic data sets are rarely introduced in the biology classroom. We prepared an online inquiry activity based on authentic gross characteristics…

On September 21, 1922, an eclipse of the Sun at Wallal in north-west Australia provided definitive proof that Einstein's theory of gravity is correct. By proving that space is elastic, it paved the way for the discovery of gravitational waves in 2015, in which Australia also played a major role. David Blair, Jyoti Kaur, and Anastasia Popkova are…

To combat environmental apathy, the authors seek to help students develop environmental knowledge, ethics, and "critical-thinking skills that will prepare them to evaluate issues and make informed decisions regarding stewardship of the planet". This article describes scientific, place-based investigations of local species and their…

Education and Public outreach is an important part of the activities of universities and research institutions. Moreover, public outreach is becoming an interesting career path, suited for young research scientists with strong communication skills and a broad research background. To address these opportunities and challenges, we decided to set up…

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…

Catalysis is an essential concept in chemistry, playing a key role in industrial processes. Catalysis has been considered to be challenging not only for university students to comprehend but also for the teachers. In this Laboratory Experiment, we have described a simple activity for demonstrating the concept of catalysis using thread-based…

Boasting a wide range of interactive and engaging features, narrative-based learning has become increasingly popular in educational settings. Narrative-based instructional approaches engage students in a novel set of engaging experiences for educational purposes. Although it is not a new concept, the implications of narrative-based learning for…
