Paal--Knorr reactions are a classical method for synthesizing pyrroles, using 1,4-dicarbonyl compound and amine as reactants. It has the characteristics of green chemistry, as only two molecules of water are lost. In this teaching and learning experiment, 2,5-hexanedione and 4-"tert"-butylaniline were used to synthesize…

The chemical experiment in this study is specifically created for undergraduate students studying energy and the environment. The target of the experiment is for students to comprehend the deactivation mechanism of the Ce/TiO[subscript 2] catalyst by oxides of phosphorus through practical experiments and enhance their knowledge of environmental…

The flue gas from waste incineration power plants contains high-level zinc species that may deactivate the catalyst for selective catalytic reduction (SCR) of nitrogen oxides (NO[subscript x]) with NH[subscript 3]. A comparison experiment was designed to investigate the effect of different types and Zn/Ce molar ratios on the performance of…

Green School intend to increase student connection to the environment, and have the potential to increase achievement through opportunities for hands-on science learning. This study utilizes publicly available data on all public schools in Maryland to examine the extent to which the Green School designation relates to changes in science…

As the use of plastics expands, microplastic concentrations increase in aquatic environments and negatively impact water, soil, and animals inhabiting these areas. Microplastic research frequently incorporates citizen science to assist in data collection and environmental education. These projects provide opportunities for greater societal…

Sustaining a broad diversity of plants is key for a sustainable future. For instance, providing a variety of flowering plants in urban and agricultural landscapes mitigates the current decline of pollinators and biodiversity in general. Therefore, educating about the diversity of flowering plants has high current relevance for biology and…

We are becoming more and more aware of the marks our human existence is leaving on our global environment: the Anthropocene as discourse of that awareness is turning into a living and lived-in reality. I argue that such discourse cannot remain the purview of the natural and social sciences alone: culture must be recognized in its pivotal role of…

Hydrogels are soft water-rich materials with physical properties that can be easily tuned by modifying their network structure. For instance, increasing or decreasing the cross-linking density has a profound effect on their water absorption capabilities and mechanical strength. These physical changes are showcased in a new experiment for organic…

Herbaria, collections of preserved plant specimens, have existed for 500 years as repositories of information about plants. Many of these collections are now being digitized, making them available to a much broader audience including students and teachers. Specimens can be used in a variety of different contexts in teaching biology, including from…

Plastic recycling has gained increasing attention due to the negative impacts of improper plastic waste management and its end-of-life outcomes. Despite growing research and educational efforts on sustainability, the integration of community service into student learning experiences remains limited. To address this gap and promote sustainable…

Nitrate is a crucial parameter for assessing water quality, owing to its dual function in ecological systems. These functions can be beneficial or detrimental depending on whether nitrate concentrations are low or high, respectively. The ultraviolet spectrophotometric method (standard as 4500-NO[subscript 3]--B) is a classic method for determining…

Politics and science are inextricably connected, particularly in relation to the climate emergency and other environmental crises, yet science education is an often overlooked site for engaging with the political dimensions of environmental issues. This study examines how science teachers in England experience politics--specifically political…

Programs that emphasize the important, multifaceted roles that soils play as the interfaces between humanity and the earth are needed to attract new students from diverse backgrounds. The Basic and Environmental Soil Science Training Research Experience for Undergraduates (BESST REU) site aims to provide undergraduates from a variety of science,…

A perennial goal of science educators is to develop functional scientific literacy in their students, especially those who will not become professional scientists. This article provides an example of implementing a socioscientific issues approach in an undergraduate environmental science course that enables students to develop the knowledge,…

Education is considered to be one of the key tools for addressing sustainable environmental conservation while balancing sustainable socio-economic development to achieve Gross National Happiness in Bhutan. The Environmental Science subject was introduced to prepare students with knowledge, values, and skills to address sustainability. This study…
