What's in the box
- 5 Field Loggers, labelled A to E
- 5 temperature probes and shade cups, plus a spare probe
- Foam-lined hard case
- Teacher guide and rubric
Five loggers is enough for a whole class in teams of five or six. Every team measures the same way, so the class results can be compared fairly on the board, which is the point of the Reveal in every Fieldbook lesson.
The hard case keeps the set together from year to year. Batteries and probes are the only parts that wear out, and both are cheap to replace.
