Oh, Pil-Kwang; Kang, Seong-Joo – Journal of Chemical Education, 2021
Artificial intelligence (AI) is receiving a lot of attention in various fields. There is a need for educating students in AI technology. In this context, we have created a new type of carbon dioxide fountain by integrating AI with the well-established Arduino-carbon dioxide fountain experiment. This experiment consists of an Arduino…

Cooper, Paul D.; Walser, Jacob – Journal of Chemical Education, 2019
Rovibrational spectroscopy is a fundamental component of most physical chemistry curricula. This article describes an adaption of the rovibrational spectroscopy of carbon dioxide experiment that can be used as a stand-alone experiment or in conjunction with a traditional hydrogen chloride experiment. The case is made that the laboratory…

Ng, Enoch Ming Wei; Song, Zhixiong; Yau, Chin Doong; Liew, Oi Wah; Ng, Tuck Wah – Journal of Chemical Education, 2021
The reaction between hydrochloric acid and calcium carbonate to produce carbon dioxide gas is a popular and engaging experiment to illustrate chemical reactions that result in the production of gases. It also provides a useful model for teaching concepts related to the effects of concentration on reaction rates. Although a prepared hydrochloric…

Malasidis, Vasileios; Dintsios, Nikolaos – Physics Education, 2021
The present paper examines whether there exists a change in the concentration of carbon dioxide that is trapped in the surgical facemask during the procedure of respiration and whether the results of the sequestered CO[subscript 2] can have harmful effects on the human organism. In order to answer the research questions, an experiment has been…

Scholes, Colin A.; Hu, Guoping – Chemical Engineering Education, 2021
A practical for students to experience a process plant is presented, based on operating a solvent absorption plant for carbon dioxide capture. The student must operate the plant in assigned roles that closely identify with a chemical plant environment, to achieve specific performance targets. Students must overcome technical challenges that…

Killian, Benjamin J.; Singletary, Steven – Journal of Chemical Education, 2022
We present a modernization of the undergraduate physical chemistry laboratory experiment for determining the speed of sound in various gases from resonant frequencies in a spherical resonator. The resonator (schematic IR = 7.5 cm) is constructed by 3D printing with eco-friendly poly(lactic acid), a commercially viable alternative to traditional…

Curran, Mary Carla; Ramsey, Andrée L.; Bower, Amy S. – Science Activities: Projects and Curriculum Ideas in STEM Classrooms, 2021
Oceans play an important role in weather and climate through transfers of heat and moisture to the atmosphere, and by moving heat and climate-relevant molecules like carbon dioxide around the globe. Energy also transfers from the atmosphere to the surface of the ocean, traveling down through the water column creating ocean currents that transport…

Sumrall, William J.; Sumrall, Kristen M. – Science Activities: Projects and Curriculum Ideas in STEM Classrooms, 2021
This article's focus was on transitioning middle grade students from the position of having a positive environmental attitude toward their exhibiting actual behaviors that address climate change. Using research by Newhouse's criteria of changing attitude into behavior, specific activities were developed and tested in a eighth grade classroom. The…

Macalalag, Augusto Z.; Johnson, Joseph; Lai, Michelle – Cultural Studies of Science Education, 2020
Socioscientific Issues (SSI) provide a strong framework for engaging students and teachers in meaningful and relevant scientific discourse in the development of functional scientific literacy. However, while most teachers recognize the value of introducing students to SSI, they themselves have limited knowledge of SSI and often lack the confidence…

Halpern, Arthur M.; Noll, Robert J. – Journal of Chemical Education, 2020
The fundamental principles and applications of thermodynamics and single-component phase equilibrium are used to explain and quantitatively analyze the operation and performance of the vapor-compression refrigerator (VCR). Carbon dioxide is used as the refrigerant. The four processes (or steps) that comprise the VCR refrigeration cycle are…

Jensen, Andrew; Brown, Niamh; Kosacki, Nathalie; Spacek, Sara; Bradley, Alexander; Katz, Daniel; Jimenez, Jose L.; de Gouw, Joost – Journal of Chemical Education, 2022
The COVID-19 pandemic has posed a challenge for maintaining an engaging learning environment while using remote laboratory formats. In this work, we describe a Student Choice Project (SCP) in an undergraduate instrumental analysis course that was adapted for remote learning without sacrificing research-based learning goals. We discuss the…

Sieg, Philip G.; Berner, William; Harnish, Peter K.; Nelson, Philip C. – Physics Teacher, 2019
Climate is a topic of great concern to students, but it remains difficult to discuss scientifically. We are bombarded daily by emotional messaging for and against the proposition that human activities are altering the climate in ways that may have catastrophic effects. But it often seems that those predictions rest entirely on massive computer…

Ribeiro, Carla – School Science Review, 2014
Global warming is a current environmental issue that has been linked to an increase in anthropogenic carbon dioxide in the atmosphere. To raise awareness of the problem, various simple experiments have been proposed to demonstrate the effect of carbon dioxide on the planet's temperature. This article describes a similar experiment, which…

Jones, Richard C.; Bagheri, Nazgol – Geography Teacher, 2019
This exercise introduces students to the observation that warming is unequal at the level of regions and countries, helps them analyze why this is so, and encourages reflection on actions by specific countries. In addition, students will uncover the relative roles of methane and carbon dioxide in local warming, the role of greenhouse gas emissions…

Wright, Suzie; Watson, Jane; Smith, Caroline; Fitzallen, Noleine – Teaching Science, 2021
Life would not be possible without plants. Plants supply food to many organisms (including people), produce oxygen, absorb carbon dioxide from the air, provide products for human use, and homes for many other living things. It is not surprising, therefore, that plant growth is a familiar topic in the primary school science curriculum. This paper…
