A hydroponics experiment growing microgreens was piloted by seniors where trials were conducted over 9-day growth periods and designed to test 12 different growth conditions in triplicate, including varying nutrient supply, nutrient flow rate, and seed density. Plant growth was assessed through changes in daily mass, height, and final dry weight.…

Explanation of natural phenomena at one level of biological organisation almost always involves causes that are found at other levels. Although scientists thinking across levels find it easy to explain physiological phenomena, students often perceive this as a challenge. We developed a new graphic organiser called Zoom Map, which is a mode for…

The current study uses the Rasch Model to measure lower-secondary school students' critical thinking skills on photosynthesis topics. Critical thinking skills are considered essential in science education, but few valid and practical measurement instruments remain. The current study fills the gap by adapting the instrument from the Watson-Glaser…

The wonderful plants and animals of the Daintree Rainforest in Queensland, Australia, are at risk of extinction. They and the rainforests of the world must be protected by taking action on climate change.

This study investigates the influence of plant landscape colors on the quality of life of college students at Sichuan Vocational College of Health and Rehabilitation in Zigong City, China. The research employed a mixed-methods approach, integrating quantitative data from 328 student questionnaires with qualitative insights from in-depth interviews…

This project centered Indigenous history, culture, and sovereignty while also teaching about scientific principles connected to plants, agriculture, and gardening--key ideas the authors and professors hoped their preservice teachers (PSTs) would be able to use with the young learners in their future classrooms. The purpose of this work is for PSTs…

Learning is a continuous process involving teachers, students, materials, and the environment to achieve specific goals. One important aspect of learning is the use of learning media. This study develops a learning media in the form of a magazine on the human circulatory system and an inventory of antihypertensive medicinal plants in Sari Makmur…

Despite the growing importance of agricultural microbiology at the applied, productive and ecological levels, undergraduate degrees in Agronomy generally do not feature much microbiological experimentation. To address this deficiency, we have designed an experimental programme that evaluates the potential of plant growth-promoting rhizobacteria…

This research envisioned as its main objective the comprehension of the process of knowledge production concerning the Afro-Brazilian boldo ("Plectranthus barbatus Andrews"), with the contributions from both scientists and the Afro-Brazilian people. As specific objectives, we attempted to reconstruct the research pathways traveled by…

Plant blindness is becoming a universal phenomenon among both students and adults. They do not know the names of the plants in their immediate environment, nor are they interested in familiarising themselves with the plants that surround them. Teachers and outdoor education can play a vital role in reversing and preventing this phenomenon;…

The activity described here was designed to center on the observation of circadian rhythms in plants through the example of growing beans. The aim was to develop students' skills of systematic observation of various variables in the long-term. Our study took place at a Science and Arts Center with 17 gifted students in the third and fourth grades…

The percentage of children with certain allergic conditions has increased over previous decades. Seasonal allergies, which includes hay fever, allergic rhinitis, and allergic conjunctivitis, causes sneezing, cough, runny nose, and itchy eyes. Eczema, also known as atopic dermatitis, causes itchy, bumpy rashes and thickened skin that can appear…

Giant kelp ("Macrocystis pyrifera") forests are icons of marine beauty, acting as critical marine ecosystems with great ecological and economic value. Kelp forests are hot spots for biodiversity and provide myriad ecosystem services such as nursery habitat for commercial fisheries, nutrient cycling, wave attenuation, as well as…

The understanding of analytical chemistry and its application in different areas of life science is something that should be encouraged for students studying chemistry, and also something that appeals to many students. Life science includes a vast variety of areas, out of which some are more easily approached in student projects. The chemical…

Critical analysis (CA) skills are crucial in higher education and should be incorporated into the curriculum at that level. The unique characteristics of abstract biology materials and the involvement of prospective Biology teachers (PBTs) in scientific investigation activities make them highly relevant for teaching CA skills. Inquiry activities…
