Learning Goals
Students will be able to analyze properties of substances before and after they interact to determine whether a chemical reaction occurred using observable evidence.
Students will be able to undertake a design project to construct, test, and modify a school-safe reaction-based prototype that either releases or absorbs thermal energy.
Students will be able to define measurable criteria and constraints for a chemical-reaction design problem in a school-community context.
Students will be able to compare multiple reaction concepts using a decision matrix and justify a selection with evidence from scientific sources and test data.
Students will be able to communicate claim-evidence-reasoning explanations that connect reaction data to design choices and product performance.
Students will be able to evaluate peer feedback and use it to revise a chemical-reaction prototype and team process.

Individual Chemical Reaction Design Brief with Decision Matrix and Annotated Prototype Sketches
Each student will submit an engineering design brief showing at least three original solution ideas, a decision matrix, annotated sketches, and a written justification for the chosen concept. The brief proves individual mastery of the reaction science and the reasoning behind a safe, low-waste design.
Tested Low-Waste Reaction Prototype Showcase for a School-Community Need
Teams will build, test, revise, and present one functional prototype: either a low-waste lava lamp model or a school-safe fizzy handwarmer. The showcase must include performance data, revision evidence, trade-off reasoning, and a brief presentation explaining how the final design meets the community need.
