Learning Goals
Students will be able to analyze before-and-after property, mass, and temperature data to determine whether a chemical reaction occurred and whether it absorbed or released thermal energy.
Students will be able to develop and revise particle models of chemical reactions to explain the rearrangement and conservation of atoms, matter, and energy.
Students will be able to plan a controlled investigation of how type of matter and mass affect energy transfer and temperature change while applying laboratory safety practices.
Students will be able to generate and evaluate multiple designs for a safe device that uses a chemical process to absorb or release thermal energy according to measurable criteria and constraints.
Students will be able to construct, test, and optimize a thermal-energy device using quantitative performance data and feedback from failed or incomplete trials.
Students will be able to collaborate and communicate an evidence-based explanation of their device's chemical reaction, energy transfer, performance, trade-offs, and limitations.
Products
Chemical-Reaction Engineering Investigation Notebook
Each student independently documents safe investigation plans, raw and graphed data, particle models, scientific explanations, multiple device concepts, a decision matrix, test analysis, progress reflections, and evidence-based revisions. The notebook also explains the student's contributions to team decisions and preparation for the Reaction Roadshow.
Tested Thermal-Reaction Device and Reaction Roadshow Demonstration
Each team constructs, safely tests, and revises a device that absorbs or releases thermal energy through a teacher-approved chemical process, then presents its performance data, particle models, design trade-offs, failures, revisions, and limitations. Team members share responsibility for a short interactive demonstration and evidence-based explanation for other classes and invited community partners.
