Assess students' ability to apply principles of solar heat absorption and experimental design by planning, building, testing, and improving a simple solar oven. The quiz should cover concepts (solar radiation, absorption vs. reflection, insulation), material choices (dark interiors, reflective panels, insulating layers), controlling variables (sun angle, enclosure, vents), making hypotheses, designing controlled trials, collecting and interpreting temperature vs. time data, calculating heat gain, identifying heat losses, proposing evidence-based design improvements, and documenting safety procedures.
