Education that covers topics such as climate change is critical to developing future scientists and researchers. Facilitating students' recognition of climate change as it occurs in their community can strengthen engagement with the content. Here, we highlight our work in developing a large-scale activity that introduced many facets of climate…

In the early modern era, Spanish missionaries, cosmographers, chroniclers, and physicians wrote major studies on botany, ethnography, navigation, Indigenous languages, war, and history, aided by capable, though often reluctant, Indigenous informants. They penned this rich body of scholarship using iron gall ink -- a mixture of tannins, sulfates,…

A comprehensive undergraduate experiment about extraction, separation, and identification of essential oils (EOs) from a natural plant is described. "Acori tatarinowii" Rhizoma (ATR) was used as the raw plant material. Two devices (Soxhlet and Clevenger) with different extraction principles were employed for EO extraction from ATR,…

Engaging students in science education while tapping into their innate curiosity is a crucial aim for educators. This article presents a collaborative program between a botanical garden and public high school, aimed at engaging students in botany through authentic research experiences. Beginning in 10th grade and continuing through their…

Active learning pedagogies offer opportunities to increase student engagement and interest in plants. The Mystery Plant Project is a hands-on, semester-long active learning pedagogy I developed for an introductory, undergraduate Plant Biology course. Students investigate various aspects of their mystery plant species using observations, and…

For most people, coffee roasting is a mysterious process. Chemically, it's equally mysterious; the roasting process gives rise to over 800 compounds. The science of coffee, from seed to bean to cup of aromatic brew, includes multiple areas of science content for students, and actively engages them in many science and engineering practices. Ask…

Secondary metabolite compounds contained in each plant genus have certain characteristics, which is true also of the flavonoid in the genus "Artocarpus." In the experiment described here, third-year undergraduate students performed the isolation and characterization of cycloartocarpin from the roots of "Artocarpus altilis"…

A set of core ideas in the life sciences revolve around genetics, variation, and inheritance. While the "Next Generation Science Standards" (NGSS; NGSS Lead States 2013) emphasize teaching and learning about these concepts across K-12 grades, it is critical for early learners to begin to develop understanding of them. By the end of fifth…

Social connections are crucial for today's middle and high school students. We address this social need through a 3-H Social and Emotional Learning (SEL) Cycle. Through the Three Sisters Garden activity presented here, we teach secondary school students about biodiversity and sustainability as we integrate the arts into STEM (STEAM). Students…

Food security is one of the most pressing concerns of our times. Despite the vast opportunities, there is a shortage of skilled professionals in the food, agriculture, and plant sciences. Although most programs focused on addressing this concern have targeted students, we have often overlooked another critical group--the teachers. To address this…

Systems thinking is highly desirable for re-imagining chemistry education, which will help in the development of an integrated and sustainable approach that takes into account the interdependence of a system under study with other components of the ecosystem rather than practicing a fragmented approach. Thus, to develop a systems' perspective into…

The lichen is an ideal subject for student study because it is omnipresent in school yards, easily collected and observed year-round, a pioneer of evolution on land, and a bioindicator of air pollution. After doing fieldwork on this unusual composite organism as an apprentice with a team of lichenologists, Sarah Thorne developed Learning Lichens.…

Because honeybees are so crucial to the ecosystems in which they exist, educating younger children on the usefulness and relative harmlessness of honeybees may be key to ensuring their survival among future generations. Described here is a unit that addresses the critical role of the honeybee in pollinating flowers using the 5E learning cycle…

The practice of RNA isolation in undergraduate experimental courses is rare because of the existence of robust, ubiquitous and stable ribonucleases. We reported here modifications to our original protocol for RNA isolation from plant tissues, including the recovery of nucleic acids by ethanol precipitation at 0 degrees C for 10 min and the…

Allelopathy plays crucial roles in invasive plant viability and agricultural production systems. However, there is no well-established hands-on learning activity to teach the concept of allelopathy. Nor is there an activity which allows students to gain knowledge about glucosinolates and their corresponding enzyme, myrosinase, which are present in…
