This book provides teachers with 50 dynamic activities to teach science, through music, food, games, literature, community, environment, and everyday objects. The authors share tried and tested ideas from their collective 75 years of teaching experiences. For the busy teacher with little time to plan lessons, resources are provided that include…

The lateral flow immunoassay (LFIA) is a simple and cost-effective rapid diagnostic test designed for the on-site detection of disease biomarkers. In the context of introducing this technique to undergraduate biotechnology students, we propose a comprehensive 5 h laboratory experiment. This experiment covers various aspects, including the…

This bibliometric analysis investigates the impact of Project-Based Assessments (PBAs) on conceptual understanding in STEM education from 2019 to 2024. By examining a dataset of 996 publications, the study highlights significant fluctuations in research outputs and the evolving focus on educational methodologies, particularly noting an…

Photocatalytic degradation of methylene blue was implemented as a laboratory experiment by the undergraduate students majoring in chemical education using graphene (GR)/TiO[subscript 2] as a catalyst. These chemistry preservice teachers synthesized a GR/TiO[subscript 2] composite and used it to degrade wastewater containing methylene blue under…

Three-dimensional symmetry plays a crucial role in crystallography education. The educational process can be facilitated by introducing the analysis of friezes and plane patterns such as parquets before presenting more sophisticated crystal structures. Analysis of the symmetry of parquets can serve as an opportunity to follow the full routine of…

Electrophoresis is integral to analytical and biochemistry experiences in undergraduate education; however, fundamental principles of the method are often taught in upper-level laboratories through hands-on experiences. A laboratory activity is reported that teaches the concepts of electrophoretic mobility and electroosmotic flow. A single…

We have revamped a classic analytical chemistry laboratory experiment, "Determination of an Unknown Acid", to provide students an opportunity to learn about new advances in the material sciences and their applications in analytical chemistry in an effort to reinforce the key concepts of chemical analysis. Specifically, students were…

Anthocyanins are natural pigments belonging to the flavonoid family that generate the red, blue, and purple colors of fruits, vegetables, and flowers. Their structure and color are dependent on various factors, like the pH. Anthocyanins appear red in acidic, purple in neutral, and blue in basic solutions, making them suitable for use as natural pH…

There is a disconnect between the cutting-edge research done in academic laboratories, such as nanotechnology, and what is taught in undergraduate laboratories. In the current undergraduate curriculum, very few students get a chance to do hands-on experiments in nanotechnology-related fields, most of which are through selective undergraduate…

Students in the intermediate grades love to talk--but not necessarily about making sense of what they are learning. How do teachers design classrooms that cultivate productive discourse? How do they get out of the way and teach children to learn? First, let's give them something to talk about. Second, teachers need to teach them how to engage in…

It can be hugely beneficial for teachers to 'buy in' an expert for a day in an area that they are focusing on. Children are inspired by a special visitor and it can provide a new perspective to a topic and invigorate and extend learning. The variety of workshops and visitors available is astonishing. Students can be transported to outer space or…

NMR is a fundamental part of any undergraduate chemistry degree, and training students how to measure and interpret NMR spectra is essential for postgraduate research or chemistry-based careers. Traditionally, the undergraduate laboratory experience with NMR is restricted to sample submission for NMR analysis, which is typically conducted by a…

Students need procedural understanding--that is, knowledge of the procedures that scientists use to establish scientific evidence (also known as "concepts of evidence"), to successfully perform scientific investigations, and to evaluate public and scientific claims. However, concepts of evidence are seldom explicitly targeted in routine…

Sets of models of molecules (which are of interest for teaching molecular structure, symmetry, and related topics in many chemical disciplines) were prepared and made available either for self-directed 3D-printing or through the 3D-printing company Shapeways providing 3D-printing as a service. This allows teachers to save time on searching for…

Hands-on learning in a laboratory is an integral part of the undergraduate experience for chemistry students. However, with the onset of the COVID-19 pandemic, an opportunity for this approach was not possible. The pandemic has been forcing instructors to explore the remote setting instead of the laboratory. There are several commercially…
