📊 Spreadsheet Schema Build

Students build a digital spreadsheet template in Google Sheets or Excel for baseline and ongoing measurements, including light, moisture, temperature, pH, plant size, dates, unit labels, and anomaly notes. The teacher gives just-in-time instruction on column naming, data validation, drop-down menus, frozen headers, and separating raw observations from interpretations. Teams test the sheet with five sample entries from different radish systems and correct layout problems.
