📊 Spreadsheet Setup and Baseline Logging

Students build a shared digital spreadsheet for the investigation notebook using columns for date, system type, light, moisture, temperature, pH, plant size, and notes. The teacher models clean data entry, units, labels, and how to separate raw observations from interpretations; students then enter baseline measurements from Day 1 and practice simple sorting and conditional formatting. Teams compare spreadsheet structures and revise for consistency before future data collection begins.
