Just how cold is it? Tracking the temperature calls on
observation, math, and writing skills — after you measure it.
This oversized instrument lets children observe, measure,
record, and graph ambient temperature on both the Fahrenheit and
Celsius (centigrade) scales, illustrating the relationship
between the two measurement systems. Clear, easy-to-read
numbers; sturdy plastic. Easy to mount with household screws
(not included); 15". Ages 5 and up. Please note: This
thermometer does not contain mercury.
