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…

Biological interactions and associations underlie life's processes at every level of organization. Here, we present a classroom activity that allows students to visualize and understand the connections within almost any biological system, from cell functions to ecological relationships. We recommend that instructors implement this activity to…

Idiograms are graphical representations in which chromosomes appear ordered by their relative size, homology groups, and the presence of cytogenetic landmarks such as centromeres, secondary constrictions, and banding patterns. They have become crucial elements in cytogenetic research. Here, we describe a simple protocol for spreadsheet software to…

Climate change caused predominately by carbon dioxide (CO2) from fossil fuel use is a critical issue for our future. It is incumbent on science educators to learn about it and teach it in ways that illustrate the power of science to understand climatic changes and model past, present, and possible climate futures. It is equally important for…

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…

The rise of "big data" within the biological sciences has resulted in an urgent demand for coding skills in the next generation of scientists. To address this issue, several institutions and departments across the country have incorporated coding into their curricula. I describe a coding module developed and deployed in an undergraduate…

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…

Computational thinking (CT) is a thought process composed of computer science ideas and skills that can be applied to solve problems and better understand the world around us. With the increase in technology and computing, STEM disciplines are becoming interwoven with computing. In order to better prepare students for STEM careers, computational…

Charles Darwin would be pleased to know that elementary school children in states that have adopted the "Next Generation Science Standards" (NGSS) are expected to demonstrate their understanding of several core evolutionary concepts, including trait variation and inheritance, fossils and extinct organisms, common ancestry, natural…

Many of today's adolescents have little to no connection to their environments or the native plants and animals that share their spaces. This is primarily due to a significant decrease in the amount of time children spend outdoors now, compared with children in the mid to late 20th century, compounded by a lack of natural history and outdoor…

High school biology students are provided few classroom opportunities to learn natural history or to see themselves as scientists. This poses a risk to their gaining the basic knowledge needed to play a positive role in the biodiversity crisis. However, science-as-practice in the classroom introduces the opportunity to equip students with…

The ability to make criteria-based and thought-out decisions in everyday life as well as to answer questions pertaining to society at large, such as those regarding climate change and the loss of biodiversity, is becoming more and more important against the backdrop of an increasingly complex world with a wide range of options for action or…

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…

This paper presents a novel approach to teaching how vaccines work in the body, and introduces a community outreach project and activity we piloted with youth. Our Nuestra Ciencia program addresses scientific misconceptions among bilingual elementary school children in engaging and scientifically accurate ways. Utilizing analogies and…

In this classroom activity, students build a phylogeny for woody plant species based on the morphology of their twigs. Using any available twigs, students can practice the process of cladistics to test evolutionary hypotheses for real organisms. They identify homologous characters, determine polarity through outgroup comparison, and construct a…
