Can You See the Heat? – Using a Thermal Imaging Camera in the Chemistry Classroom

Abstract

Thermal imaging cameras can be a very useful help when observing chemical experiments. They enable the observation of phenomena which are not visible to the human eye. In this paper a set of school experiments is described in which the use of a thermal imaging camera gives additional information on ongoing processes. Additionally an e-book that was designed as accompanying learning material is presented.

Promoting Education for Sustainable Development with an Interactive Digital Learning Companion Students Use to Perform Collaborative Phosphorus Recovery Experiments and Reporting

“…3,9 There are several examples of these Multitouch Learning Books. [10][11][12] But regional references or individual class-internal support cannot be taken into account-a central need that mainly affects Schülerlabor. Furthermore, it can take much time to create these e-books; thus, they are often not adapted to current events (e.g., Fridays for Future).…”

“…The second type of learning companion of MLBs cannot be adapted by teachers themselves. These are only “ready to use”; however, they have been approved by professionals to align with the curriculum. , There are several examples of these multitouch learning books. − But regional references or individual class-internal support cannot be taken into account, a central need that mainly affects Schülerlabor. Furthermore, it can take much time to create these e-books; thus, they are often not adapted to current events (e.g., Fridays for Future).…”

Imaging meets chemistry: The application of a thermal imaging camera in chemistry classes of secondary schools first stage

“…Die Überlegung, Wärmebildkameras auch im naturwissenschaftlichen Unterricht einzusetzen, ist nicht neu, wie die Sammlungen physikalischer Experimente von Grötzebauch [2] und von Strahl und Müller [3] zeigen. Eine beeindruckende Zusammenstellung physikalischer und chemische Experimente haben Bohrmann‐Linde und Kleefeldt in vielfältiger Weise erstellt [4–8]. Gerade bei der Betrachtung der Energieumsätze physikalischer Vorgänge und chemischer Reaktionen ergeben sich durch die Thermografie neue Möglichkeiten der Prozessanalyse, wie die Beobachtung der Kristallisation eines Taschenwärmers, von der wir bereits berichteten [9, 10].…”

Invisibility Cloaks and Hot Reactions: Applying Infrared Thermography in the Chemistry Education Laboratory

“…IR thermography has been applied in numerous contexts including materials analysis, , various medical evaluation procedures, , crop phenotyping, and detection of bacteria, and in strategies for low-cost, high-throughput enthalpimetric analyses. − The flexible application of IR thermography brings to light several key features that, as we have discussed in prior work, represent unique affordances with the potential to enhance learning of fundamental chemistry concepts by students: (i) accelerated data collection arising from the ability to capture the temperatures of multiple objects in real time, (ii) visual feedback for the user rendered with intuitive coloration, and (iii) capture of thermal data that are correlated over time and space (i.e., the ability to visualize temperature gradients across samples and their changes over time that would be difficult to record with single-point thermometers) . IR thermography has been used in educational settings, especially in physics coursework, as an introduction to light–matter interactions and heat transfer. − Notably, a recently published article also describes the use of IR thermography to explore various reactions and processes in support of chemistry education . Here, we discuss expanding on both these modules and our previous work to create more quantitative chemistry lab-focused activities that can be easily integrated into a traditional lab curriculum.…”
