Field notes
The classroom flow starts with a question set: teachers may use middle- or high-school prompts or add their own, then share a six-character code. Students provide a first name, while the teacher view shows answers as they arrive and offers spreadsheet export. Listed activities include Moon phases, greenhouse effects, seasons, and a carbon-cycle role-play; several carry standards labels such as MS-ESS1-1 and HS-ESS2-6. The homepage states student names and answers are deleted after a year.
