Electron spin resonance (ESR) or electron paramagnetic resonance (EPR) spectroscopy is an incisive technique for the characterization of paramagnetic centers in inorganic, bioinorganic, and organic molecules and materials. These measurements are enabled with the help of paramagnetic species, such as organic free radicals and ions, electronically…

In this supplement to our second-year supercapacitor lab (Bringing Real-World Energy-Storage Research into a Second-Year Physical-Chemistry Lab Using a MnO[subscript 2]-Based Supercapacitor. "J. Chem. Educ." 2018, 95 (11), 2028-2033), we incorporate a color indicator as indirect evidence for the manganese oxide's pseudocapacitive…

While fungi play a vital role in Earth's ecosystems, they are not highlighted in the Next Generation Science Standards (NGSS). This article contains a unit plan to introduce students to the fungal kingdom, characteristics of fungi, and their role as decomposers. The unit plan is written in a 5E model format and can be adjusted for any type of…

This activity introduces droplet-based millifluidics and the usage of aqueous droplets as independent chemical microreactors for reaction-kinetics studies. Students build their own droplet generators from common macroscopic glassware and connecting parts to create trains of millimeter-sized droplets in which a redox reaction takes place. The…

Our study evaluates students' approaches to and perceptions of the use of hands-on at-home laboratory kits (HALK) experiments, open-source computer-based simulations (OSCBS), and their combination (OSCBS-HALK) in undergraduate introductory asynchronous online physics courses. Anonymous survey data from students who had completed online physics…

Using Mary Shelley's "Frankenstein" as inspiration, this paper presents a Frankenstein-themed transmedia storytelling experience, which encompasses simple hands-on activities and an online narrative experience that allows students to model scientific work and engage in various science activities. The study aimed to test whether students…

This article illustrates a learning sequence from the Interdisciplinary Mathematics and Science (IMS) Learning project, connecting science and mathematics learning in the primary school. Exploring light and its properties involved a series of investigations conducted in Grades 4 and 5 across three classes in two schools in regional Victoria. The…

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…

Electrocardiography (ECG) is one of the most widely used methods in clinical diagnosis. Here we describe an experimental approach that offers hands-on learning of its basic principles. An experimental model that consists of a rubber foil with a low electrical conductivity and a DC power unit is used to simulate the body and the electric dipole of…

The authors describe the construction and use of tactile models for demonstrating intermolecular forces. These models are composed of inexpensive materials and can be used in college chemistry classrooms of varying levels including general and organic chemistry. The models were designed to be paired with an accompanying activity to encourage…

Finding context, examples, and ample hands-on experimentation is fundamental for understanding complex ideas in subjects such as science and math. Recent popularity of competitive robotics has become a catalyst in the development of DIY and hobby kits. Manufacturers have made available easy to work, re-configurable, and functional, structural…

Inquiry projects can play an important role in science education, despite involving significant challenges for teachers and students. Based on historical references, small groups of students and their teachers carried out inquiry projects on the ability of certain insects to 'revive' after remaining immersed in water for some time. The striking…

Augmented/virtual realities (ARs/VRs) promise to revolutionize STEM education. However, most easy-to-use tools are limited to static visualizations, which limits the approachable content, whereas more interactive and dynamic alternatives require costly hardware, preventing large-scale use and evaluation of pedagogical effects. Here, we introduce…

Guided-inquiry experiments are an important tool for helping students develop scientific practices such as hypothesizing and problem solving. In organic chemistry, these types of experiments can help students learn how to connect the theory of the reaction to the observation and data to decide how the reaction is proceeding or if it needs…

Teaching modern physics in high school is of increasingly importance as it can offer students a more realistic and updated vision of the world, and can provide an opportunity to understand the most recent scientific discoveries. In this context, general relativity (GR) occupies a prominent place, since it is related to astonishing scientific…
