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…

With the increase of waste paper, environmental pollution and atmospheric impact have become global problems. The cellulose contained in waste paper has the advantages of being renewable and biodegradable and can be applied to many fields to achieve sustainable development. At present, thermal management materials, as a new type of material, have…

Microplastics have been detected in most ecosystems around the world. They affect the environment and organisms in it, including humans and possibly their health. Hence, the analysis of microplastic occurrence in the environment is highly relevant. However, there are only a few practical and easy-to-implement methods published for school use, and…

The durability and variety of plastics mean that they can take an age to break down (or biodegrade) in the environment. Plastic carrier bags will be around for 50 to 100 years, plastic bottles for 600 years, and Styrofoam/polystyrene containers for a whopping 5000 years. As more of these plastic items are added to the ocean, they just build up and…

This article introduces a novel experiment that involves vitrimers, a new type of polymer, in polymer chemistry and physics lab courses for undergraduate students. Vitrimers are permanently cross-linked networks that can be reprocessed under certain external stimuli. Therefore, they combine the advantages of traditional thermoplastics (excellent…

Socio-scientific issues demonstrate the relationship between science, technology, and society by considering currently unresolved questions. The problem of plastics and their pollution is just one example with important implications for the planet. The aim of this paper is to revisit socio-scientific issues and see them as a way of developing…

STEM is a commonly used acronym in today's education world. Parents hear the term and hope their child's school will be embracing it, teachers plan units encompassing it, even those outside the education realm have heard it and think it is important. But, do students actually understand the four disciplines and can they clearly express what they…

Microplastic contamination of the environment is a major concern but detecting such contamination presents a challenge, particularly for particles <0.1 mm in size. Community scientists and students who participated in a plankton monitoring program and routinely examined samples of seawater using brightfield microscopy, often found fragments and…

Environmental pollution is both a worldwide and a local issue, and microplastic pollution in particular is receiving increased attention due to its prevalence and bioaccumulation potential affecting the food chain. This laboratory experiment uses current, research-based methods such that the students can determine the extent of microplastic…

Makerspaces have become very popular in education because they "provide hands-on, creative ways to encourage students to design, experiment, build, and invent as they deeply engage in science, engineering, and tinkering" (Cooper 2013). Not only do makerspaces provide a safe learning environment for students to develop their 21st century…

We report here a second semester general chemistry laboratory project themed around chitosan-alginate bioplastics. With increasing awareness of plastic pollution in the environment and the awareness of the importance for materials which are either made from renewable resources or are biodegradable, this topic provides a relevant opportunity to…

The inexpensive and disposable electrode based on a double-polymer-modified pencil lead is proposed for upper-division undergraduate instrumental laboratories to enable the highly sensitive detection of perchlorate. Students fabricate and utilize their own electrodes in the 3-4 h laboratory session to learn important concepts and methods of…

Bottled water is ubiquitous, taken for granted, and seemingly benign. Americans are consuming bottled water in massive amounts and spending a lot of money: In 2007, Americans spent $11.7 billion on 8.8 billions gallons of bottled water (Gashler 2008). That same year, two million plastic water bottles were used in the United States every five…
