This article aims to share part of some middle-term research focused on Argentinian school bathrooms. Bathrooms in Argentina emerged around 1850 and have been present - with nuances - in public and domestic buildings since the last third of the nineteenth century. Particularly, primary-school bathroom history is marked by two facts. First, these…

The COVID-19 pandemic has exposed a high level of scientific illiteracy and mistrust that pervades the scientific and medical communities. This finding has proven the necessity of updating current methods used to expose undergraduates to research. The research in traditional course-based undergraduate research experiences (CUREs) is limited by…

We are all users of lithium-ion batteries (LIBs), the electrochemical energy storage devices that revolutionized our life, making the diffusion of portable and wearable devices possible and now driving the switch from a combustion engine to electric vehicles in the transportation sector. These positive trends are however leading to two whiplash…

This work provides inspiration to foster Problem-Based Learning (PBL) in teaching practices related to waste management. Problem-Based Learning is about providing a learning environment where students can work practically and theoretically with problems of relevance for society. In this learning process, students themselves will define societally…

Plastic waste is a growing concern in recent years due to the massive increase in single-use plastic applications. Despite the ever-increasing amount of waste, recycling plastics is not a simple process due to difficulties in sorting, which results in significantly downgraded material properties. This hands-on lab experiment showcases the…

A laboratory experiment was designed to provide students with an introduction to byproduct valorization by producing an analogue of biodiesel (fatty acid ethyl esters, FAEE) via lipid extraction and subsequent transesterification from spent coffee grounds (SCG). Valorization is the process of upgrading underutilized or discarded wastes or…

This study reviewed the evolving capabilities of hydro-drones, Unmanned Aerial Vehicles (UAVs) which are used for spraying and cleaning with a focus on water management, and it revealed that the unique capabilities of hydro-drones offered the potential to create challenging and rewarding education and training programs, designed to provide new or…

To promote student involvement in the reduction of chemical waste generated by teaching laboratories, a method published by Flinn Scientific for the treatment of waste sodium molybdate has been modified for use in treating waste generated by the popular molybdenum blue method for the analysis of phosphate in natural water samples. In this teaching…

A laboratory experiment was developed to introduce undergraduate chemistry students to the chemical characterization of agroindustrial waste extracts by gas chromatography-mass spectrometry (GC--MS). The students prepared hexane and dichloromethane extracts from black pepper ("Piper nigrum" L.) waste. GC--MS analysis revealed the…

This photo essay reflects on Rafiki Theatre's recent work exploring Water, Sanitation and Hygiene (WASH) issues in refugee camps in Northern Uganda. The images portray the context, challenges and ways in which Rafiki responded to the aims set by the project donor.

Despite the attention drawn to the plastic crisis by the media and environmental campaigns, much of the practice around single-use plastic has remained unchanged. It appears that, although many know the correct position to assume regarding the issue, the 'talk' does not necessarily translate into action. This incongruity can be explained with…

Formative assessment during the course of instruction is an essential practice for supporting all students, including English learners (ELs), in the science classroom. It typically consists of three steps: (1) The teacher elicits information about student learning through various methods; (2) The teacher interprets (or makes sense of) that…

College and university leaders are fighting the battle of their lives to maximize their institutions' financial wellbeing. With COVID-19 further weakening institutions' financial positions, are there any hidden sources of savings still to be had? The answer, often, is yes--even for the many institutions who have already made substantial cuts. It…

The complexities of the civil rights movement are rarely presented in elementary social studies. Year after year, students repeat the same decontextualized "I Have a Dream" crafts and assignments, tasks that do little to help students understand the country's history of racism or the racial dynamics of today. Instead of perpetuating the…

Although residues and resource shortages are major problems of modern living, these topics are not usually properly covered in university curricula. To tackle this situation, we have guided undergraduate students through the design of a group of active learning activities, to demonstrate the science behind separation and recycling: trash…
