This qualitative, exploratory, comparative case study examined plant-based innovations in Title I PK12 public-school nutrition programs (PSNPs) in the context of the School Health Index (SHI) and Whole School, Whole Community, Whole Child (WSCC) objectives. The study explored the perceptions of PK12 superintendents, school board members, nutrition…

The plant taxonomy textbooks that are generally used in colleges need to be complemented with a DNA-based molecular review. In general, plant taxonomy textbooks devote more space to morphology than to molecular-level characteristics. The research reported here used the results of DNA-based research to develop a molecular plant taxonomy textbook.…

In this article, I use aerial footage of the Amazon as a guiding thread to argue that the sublime is the most fitting concept to describe our aesthetic response to the representation of Amazonian nature in cinema. In my discussion of rainforest aesthetics, I focus on two Brazilian films, made ten years apart: Glauber Rocha's short "Amazonas,…

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"…

Teachers are confronted with many challenges in the science classroom. One of these challenges is finding a reliable learning approach to improve students' performance. This study used peer learning approach of teaching to help students learn and understand concepts in a photosynthesis class. The participants of the study were 40 science students…

Human cognition is influenced by natural selection which results in better information retention related to survival and faster visual recognition of potential threat. Plants are excellent models for studying human preferences because of the long evolutionary connectedness of humans with plants as food sources, although research in this field is…

Understanding the concept of electromagnetic radiation (EMR) and its interaction with matter (absorption, reflection, and transmission) can be difficult for students in seventh and eighth grade physical science classes. This inquiry-based activity (IBA) is aimed at improving their understanding of these concepts by exploring the interaction of EMR…

When student projects require an analytical step that is robust and sufficiently selective, high performance thin layer chromatography (HPTLC) is a method to be considered. However, for student laboratories not equipped for HPTLC, sample application as a sharp narrow band is a hurdle. The low eluting power of water on reversed phase plates can be…

Pigments are light-absorbing substances that are abundant in nature, serving roles in coloration, camouflage, mate/pollinator attraction and photosynthesis among higher life forms. Among microbial organisms, pigments can also be found in a wide range of phyla. While some of these pigments function in photosynthesis, namely among algae and some…

Object-based learning is an approach that aims to foster observational skills and sensory awareness. Paradoxical plant objects that do not lend themselves to all-too-easy explanations and interpretations can be used to practice the search for ecological explanations and the formation of evolutionary hypotheses. They can be the basis of…

The importance of biodiversity to the health of our planet is increasingly being discussed, not only by scientists, but by the public at large. Therefore, an understanding of how human activities are affecting biodiversity is vital for informed participation in society, and thus it is an important topic for liberal arts education. Here, I present…

This article describes the effects of a student-teacher-scientist partnership program on high school students' science outcomes. The design was a cluster-randomized trial with an analytic sample of 36 teachers randomly assigned to teach a photosynthesis- and respiration-focused module including student-designed investigations supported by online…

The exploitation of animals for human purposes raises several ethical concerns in the educational realm that ought to be carefully dealt with. Derived from the content analysis of sample of 39 Portuguese secondary and high school textbooks, this study aims to understand how factory-farmed animals are represented within the following themes: food…

The iNaturalist application has been gaining traction in both biodiversity research and education. Increasingly more research is being carried out, looking into using the iNaturalist application in biology education, to promote biodiversity and educate students about this topic. We used the PRISMA systematic literature review method to examine…

This study explores the importance of scientific observation in primary education, highlighting how the use of observation sheets can facilitate the acquisition of knowledge and the development of students' observation skills. In the research, 153 second-grade students were divided into three experimental groups, each group observing a woody plant…
