Original Prompt

Undertake a design project to construct, test, and modify a device that either releases or absorbs thermal energy by chemical processes. Emphasis is on the design, controlling the transfer of energy to the environment, and modification of a device using factors such as type and concentration of a substance. Examples of designs could involve chemical reactions such as dissolving ammonium chloride, calcium chloride or a citric acid and baking soda (sodium bicarbonate) reaction in order to warm or

This resource focuses on the application of engineering design principles to create a chemical device aimed at controlling thermal energy transfer. Students will engage in a hands-on challenge to develop a system that can either heat or cool a specified area through chemical reactions. Key considerations include thermal insulation, material safety, and effective heat transfer. The process involves brainstorming suitable reactions, creating device schematics, conducting trials, and analyzing temperature changes. The students will assess their designs based on performance constraints, propose modifications, and explore optimization strategies. The document also includes an extension challenge for advanced learners regarding additional safety features.
