🔥 Calorimeter Safety & Data Protocol Review

Teacher models proper calorimeter setup (ring stand, soda-can calorimeter, thermometer placement, water mass measurement) and reviews the shared Google Sheets data template. Students rehearse how to record mass of snack, mass of water, initial/final temperature, and observation notes (flame stability, soot, heat loss). Emphasis is placed on documenting deviations rather than fixing them silently.
