CO₂ Investigations: An Open Inquiry Experiment for General Chemistry

Abstract

This paper presents a successful, free inquiry experiment in which students devise an experiment to measure carbon dioxide in an important chemical, biological, or environmental situation. Also discussed is rationale for adopting an open inquiry experiment and how it fits into the laboratory as a whole. Typical student projects are given, and data showing this experiment's success are presented and discussed.

Using a Cooperative Hands-On General Chemistry Laboratory Framework for a Virtual General Chemistry Laboratory

“…A number of new approaches to the general chemistry laboratory have been implemented with a goal of mapping the laboratory course outcomes better to practice the competencies adopted above. A natural approach would be an inquiry-based or inductive approach to the chemistry laboratory. , One systematic approach to restructuring the laboratory experience has been the “Cooperative Learning” approach, which was adopted by our institution. , Related approaches such as Process Oriented Guided Inquiry Learning, Project Based Laboratory, Open Inquiry, or Argument Driven Inquiry share many of the same elements (such as identifying problems and planning experiments) and have all also been shown to be effective. − …”

Demonstrating CO2 Sequestration Using Olivine and Carbonated Beverages with Secondary School Students To Investigate pH and Electrical Conductivity Concepts

“…In addition, this demonstration experiment can be easily extended to open-inquiry approaches as the chemicals used are safe to handle. 3 Following Linn and Eylon, 10 the experimental results provide food for thought in a classroom discussion at secondary school level. For instance, the pouring out of the carbonated beverage during the experiment reveals gas bubbling.…”

Measuring CO2 with an Arduino: Creating a Low-Cost, Pocket-Sized Device with Flexible Applications That Yields Benefits for Students and Schools

“…Several educational experiences using CO 2 can be identified in the literature. For example, the study of how CO 2 is formed as a product of a chemical reaction or behaves under particular environmental conditions, such as pressure or temperature, can help students to develop and refine their ideas about the particle model of matter in chemistry . In other school subjects, such as biology, the study of CO 2 can be related to animal and plant respiration and can be used to help students to construct models of life .…”

In environmental sciences, CO 2 can also be used to study the greenhouse effect while constructing a light–atmosphere interaction model .…”
