Lopes, Andressa Rubim; Leandro, Luana Paganotto; Mariano, Maria Vitória Takemura; Posser, Thais; Franco, Jeferson – Biochemistry and Molecular Biology Education, 2023
Ethanol (EtOH) is among the most consumed drugs in the world. The behavior of humans after ingestion of this drug is characteristic: At low doses it may be excitatory and at higher doses, it may induce depressant/sedative effects. Similar effects are observed in the zebrafish experimental model ("Danio rerio"), which has about 70%…

Hunter Michael Craig – ProQuest LLC, 2024
The threat of climate change makes it increasingly important for biologists and the public to understand how organisms respond to temperature. The Metabolic Theory of Ecology (MTE) predicts that temperature should affect organism performance, with implications for species interactions and ecosystems that span disciplines including mathematics,…

St. John, Pamela M.; Kienzle, Scott D.; Flood, Brianna M.; Moody, Troy V.; DePaola, Nicole F.; Mass, Spencer – Journal of Chemical Education, 2021
With the enormous reliance on plastics in the world today, bisphenol A, an additive used in the synthesis of many plastics, such as polycarbonate, has been found almost everywhere in our environment including in soil, in natural waters, and inside organisms including humans. A multidisciplinary experiment is presented that involves using flatworms…

Jinhyeon Choi; Sang-Hak Jeon; Hyeon-Pyo Shim – Biochemistry and Molecular Biology Education, 2024
The aim of this study was to develop molecular genetics inquiry programs using the "eyes absent" gene of "Drosophila melanogaster." The program was composed of various molecular genetics experiments, including mutation observation, cross-breeding, searching for genetic information in web databases, gDNA extraction, and PCR.…

Bonachea, Luis A. – Journal of Biological Education, 2021
While metabolism is a fundamental process in physiology, the measurement of metabolism by living animals often requires specialized and expensive equipment. In 2016, I developed a novel laboratory exercise for animal physiology students where students were able to observe the effects of temperature and long-term temperature acclimation on the…

Carrie Ann Sharitt; Michael J. Vanni – American Biology Teacher, 2023
Many high school students learn about nutrient cycling during biology, environmental science, and agriculture classes. These lessons often focus on soil and plants, and nutrient cycling is usually taught independently from climate change. Scientists know that animals, including fish, can have strong effects on nutrient cycling (i.e., nitrogen and…

Wonhyeuk Jung; Christopher S. Dunham; Katie A. Perrotta; Yu Chen; James K. Gimzewski; Joseph A. Loo – Journal of Chemical Education, 2022
Food safety science is an important field due to its practical applications in maintaining public safety and confidence in consumer goods. A significant component of food safety science is the detection and regulation of heavy metals in food. Heavy metals such as mercury (Hg) are of particular concern because of their potential to damage the…

Vergara Sandoval, Camilo Sebastián; López Simó, Victor; Couso Lagarón, Digna – Journal of Biological Education, 2022
This research aims to analyse the progression of 13-14 year-old students' ideas regarding the concept of energy transfer by means of heat in three biological mechanisms of thermal regulation. The outputs of 270 students, grouped in 77 cooperative groups, are analysed by comparing their explanations before and after conducting an experimental…

Price, J. A.; Olver, J. – Journal of Biological Education, 2023
Most undergraduate students do not have practical experience working with model organisms despite having theoretical knowledge of their importance. This practical was developed to offer students experience working with three species of nematode, including "Caenorhabditis elegans." In the first task, students prepare slides of three…

Darling, Randi A.; Smith, Alyssa; Mello, Alex – Bioscene: Journal of College Biology Teaching, 2021
Many science departments encourage students to gain experience conducting research. However, finding ecological research projects that allow students to test a hypothesis in the field, over the relatively short time span of a semester, can be challenging. This article describes an inquiry-based research activity examining the influence that urban…

Hoffman, Janlyn R.; Brandwein, Nathan J.; Nguyen, Peter V. – Learning & Memory, 2019
Beta-adrenergic receptors ([beta]-ARs) prime hippocampal synapses to stabilize long-term potentiation (LTP). This "metaplasticity" can persist for 1-2 h after pharmacologic activation of [beta]-ARs. It requires activation of PKA (cAMP-dependent protein kinase) during [beta]-AR priming. A-kinase anchoring proteins (AKAPs) tether PKA to…

Vandervoort, Kurt – Physics Teacher, 2020
Newton's law of cooling describes an object whose temperature decreases exponentially with time. Because of its many applications, it is a frequent topic of introductory physics labs. In this article, I describe an experiment designed for the freshman year algebra-based physics course that applies this law to answering the question, "Why…

Daoud, Abdel; Nordheim, Erik V.; McGee, Seth A.; Harris, Michelle A. – Bioscene: Journal of College Biology Teaching, 2022
The California Blackworm ("Lumbriculus variegatus") is a freshwater segmented worm species that has been used by biology instructors as a model system for inquiry-based student investigations. The blackworm dorsal blood vessel pulsation rate is easily quantified. Moreover, this species can facilitate the study of neuromuscular…

Quiñones, Rosalynn; Kolling, Derrick R. J.; Shoup, Deben; Smythers, Amanda L.; Nickel, Sarah; Westfall,Tamara D.; Epperly, Courtney; Coplin, Miranda – Journal of Chemical Education, 2019
Melanoma, a type of cancer that develops in melanocytes, is usually caused by direct exposure of skin to ultraviolet (UV) radiation resulting in cellular damage. In this study, a procedure to determine the effects of various commercial sunscreens with SPF values ranging from 15 to 100 was developed using pig skin to mimic human skin. These…

Mutlu, Ayfer – Science Activities: Projects and Curriculum Ideas in STEM Classrooms, 2021
This study aimed to develop, introduce, and conduct an inquiry-driven creative drama activity. The activity, for elementary students, related to the transmission of light and full shadow. In the activity, which consisted of a warm-up, dramatization, and evaluation stages, two inquiry-based experiments were added to the dramatization stage. Thus,…
