- Three investigations as PDFs
The Field Logger does one thing honestly: it takes fair, automatic temperature and light readings at a spot and saves them by station. Kids see the number and the graph change live, so the experiment is about the science, not about squinting at a thermometer.
It’s built for the investigations every curriculum asks for: the hottest and coolest places in the schoolyard, sun versus shade, how fast a drink cools, whether a jacket keeps you warm. Plug it into any computer and the readings open as a spreadsheet. Nothing to install and nothing for IT to approve.
The Explorer is one logger for families, home educators, libraries and makers. For a class, see Classroom 5 and Audit 10.
