Human-driven carbon emissions have resulted in increased levels of dissolved carbon dioxide in the Earth's oceans. This dissolved carbon dioxide reacts with water to form carbonic acid, which impacts ocean acidity as well as the solubility of carbonate-containing compounds, with far-reaching impacts on marine ecosystems and the human communities…

In nature, we often observe interesting phenomena for which we would like to find a physical explanation. One such phenomenon is presented in this paper.

Wildland fires have become a regular aspect of life for people living in the western United States. Wildfire smoke is now impacting air quality across the United States. Unprecedented wildfires have swept through Australia, Russia, and Portugal in the last few years. Like other natural disasters, wildland fires can have a devastating impact on…

A laboratory experiment utilizing locally available Indian Gooseberry ("Phyllanthus emblica" Linn.) extract as a bioreagent to determine iron(III) is described with the goal of providing students with hands-on experience in spectrophotometry and green chemistry. Spectrophotometry was used to measure the concentration of the complex…

This paper describes the course outline for a three credit hour nonlaboratory course in Environmental Health Chemistry which was taught from 1981 until 2008 at the State University of New York College at Oneonta. The purpose of this paper is to share the lecture outline in the hopes that it might be useful to others who are preparing to teach…

A safe and inexpensive laboratory for a first-year general chemistry course has been developed which allows students to explore important properties of carbon dioxide, particularly its behavior as a greenhouse gas. Students witness and measure air displacement to compare calculated gas densities and pressures inside a CO[subscript 2]-filled…

Our connection with nature is important for mental and physical well-being and this connection depends on how we understand, value and engage with the natural world. However, there is persistent evidence that young people remain disconnected from nature. In this article we discuss reasons why many secondary schools in England are having difficulty…

In this paper, we propose and describe a new approach, named BarcodingGO, to teach environmental DNA and bioinformatics concepts to undergraduate or graduate students in molecular biology-related fields. The learning pipeline proposed here aims to solve a simulated environmental monitoring problem, in which a biodiversity survey of a particular…

We demonstrate here a novel laboratory experiment for the synthesis of gold nanoparticles (AuNPs) by using a low energy gold-sputtering method together with a modern, green, and biofriendly deep eutectic solvent (DES). The strategy is straightforward, economical, ecofriendly, rapid, and clean. It yields uniform AuNPs of 5 nm in diameter with high…

Historically, science education has not adequately addressed the concerns and values of BIPOC individuals and women, especially those who fall into both categories. One way that educators are addressing this disparity is by incorporating social justice into their curricula. Climate change is one of today's most pressing issues, and youth have much…

Using cross-grade peer mentoring as an integral component to field trip experiences can help educators realize the learning potential of nature-based experiences. When young students are paired with older students, Socratic peer dialogue deepens interest, investment, and ultimately ownership of new learning. Using peer-supported inquiry…

The human relation to things in the world is at stake in the so-called post-humanist era where the distinction between human and non-human is blurred, as indicated in a term like 'the nano-self'. How should we understand the nature of our relation to things in this era? Or how can we describe an "educationally" meaningful relation we as…

Exposure and experience with ethical dilemmas and controversial socioscientific issues provide a link to students' lives or a pathway for sympathy/empathy and care, where youth use emotion to engage with the scenario and develop critical thinking skills to respond to ethical issues. For this theoretical paper, I focus on how informal science can…

Microplastics (MPs) are small plastic particles (<5 mm in size) that are ubiquitous in the environment and have even been detected in bottled water. In this laboratory experiment, suited for instrumental or environmental chemistry classes, students detect and quantify MPs in bottled water by filtering and staining them with Nile red dye prior…

In the DISCUSS (Dialogic Inquiry for Socioscientific and Conceptual Understanding in School Science) research project, a Socioscientific Issues (SSI)-based curriculum is developed and implemented in sixth-grade science classrooms with predominantly English language learners (ELLs) in Houston, Texas. A four-week space unit is designed in…
