Flexural strengthening is essential when structures face increased loads or usage changes, requiring localized reinforcement. Carbon Fiber Reinforced Polymers (CFRP) are widely used for repairing deteriorating concrete elements, notably boosting their flexural and shear strength and prolonging their lifespan. However, CFRP applications may…

A simple, safe, and easy demonstration of the reaction of sodium peroxide with water is presented. The reaction is performed in a plastic bottle by adding water to sodium peroxide supported in a rubber "thimble"; oxygen is detected by the reignition of a glowing splint, while the generation of sodium hydroxide is indicated by…

This repeated cross-sectional pilot study examined the impact of environmental education on reducing overall waste generation among students enrolled in an environmental health course from Fall 2020 to Spring 2023. The data included trash generation, single-use plastic, and paper products. Each student logged their daily usage of these waste…

The earth is drowning in plastic waste. Yet, as the plastic waste crisis grows exponentially, responses to excess waste remain stuck around containment and management processes. These approaches fail to notice that plastics know no boundaries. We now encounter plastic rocks, plastic water, plastic bodies, plastic worlds spilling into oceans and…

Socio-scientific issues-based science instruction addresses societal-related issues to promote contemporary science education. Societal-related issues almost always have to be considered in the cultural environment to which they are relevant. This means that the cultural aspects of socio-scientific issues need to be taken into account to develop…

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…

Microplastics have been found in the most remote locations on Earth as well as in where we live, work, and play. Despite increasing research focus on microplastics, efforts to inform the public about their omnipresence have lagged. To bridge this gap between research and public knowledge, we developed a museum exhibit with interactive and…

An adipic acid esterification experiment suitable for graduate students has been developed to describe the industrial manufacture of plasticizers. Students first follow the progress of the reaction with simple acid/base titration enabling measurement of the acid number. During the workup of the reaction mixture, they learn how to manage the…

Reported herein is a chemistry experiment integrating polymer chemistry and instrumental analysis for the juniors majoring in chemistry. This experiment has a different scheduling framework than traditional experiments with a fixed lab period and schedule. The students arrange their experiment flexibly and individually. Styrene maleic anhydride…

Purpose: This study aims to combine two theories, the Theory of Planned Behaviour (TPB) and the Norm Activation Model (NAM), to investigate the relationship between the awareness of reducing single-use plastic waste's environmental cost and the behaviour to limit the use of single-use plastic products (SUPPs) by FPT university students.…

Given the severe pollution caused by traditional plastics, biodegradable plastic products (BPPs) have received great attention and are appearing in people's lives in the form of packaging bags, tableware, etc. Whether a wide variety of BPPs can truly degrade depends on the environment. Aerobic composting is the arbitration method to evaluate the…

There is a growing reliance on plastic, even though it is a synthetic material that does not decompose. This article presents a series of six mathematics activities that use plastics as the context to teach environmental education to seventh-grade students. The activities can increase students' awareness of the plastic problem while also serving…

Waste, a byproduct of human activity, can cause environmental pollution if released without proper processing. It can accumulate in piles, disturbing natural beauty and emitting unpleasant odors. The aim of this research is to from the students to care about the environment by learning with the Bubble Wrap Recycling Project, Used Plastic and…

We have developed a guided-inquiry laboratory exercise in which students perform viscosity measurements to infer the structure of poly(vinyl alcohol) (PVA) in aqueous solution. The activity combines both experiments and modeling. In the experimental portion of the exercise, students measure the viscosity of several solutions of PVA with differing…

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…
