Students will launch a six-week investigation by comparing warm-day hail events, learning how atmospheric temperature and particle state differ with altitude, and creating an initial evidence-based storm model. They will critique and revise models, consult a university atmospheric science partner, preview the three-dimensional display and Sky Science Museum Night, and update individual progress trackers after every lesson.

Students will refine questions about variable precipitation, develop testable hypotheses, and create a safe, peer-reviewed methodology for investigating cloud formation and storm movement.

Students will conduct a safe cloud-formation investigation, systematically gather weather and storm-path evidence, document anomalies, and audit the quality of their team records. They will maintain individual notebooks and update progress trackers after every lesson in preparation for evidence-based modeling in the next phase.

Students will transform investigation data into visual evidence, test explanations against patterns and anomalies, and apply particle, water-cycle, air-mass, and circulation concepts to a three-dimensional storm-path model. They will critique competing interpretations, revise their models, and document an evidence-based big idea after every lesson.

Students will evaluate peer and expert feedback, resolve conflicting evidence, revise their three-dimensional weather-system and South American climate displays, and rehearse evidence-based explanations before Sky Science Museum Night.

Students will calibrate and revise their scientific explanations, present interactive three-dimensional weather-system displays to an authentic audience at Sky Science Museum Night, and complete an individual evidence-based explanation and reflection using audience feedback.
