Temperature Investigation Question 1 gave students experience with relative
temperature (i.e. warmer, cooler). Your students can be very adept at
observing things compared to one another, and observing changes. They
may have less understanding about how conditions and changes can be measured
using units. This investigation will help them understand that temperature
can be measured using standard units (in this case degrees Fahrenheit
and degrees Celsius.)
