I wonder if it wouldn't have been more effective to put the different
materials out in the sun for a period of time and then let the students simply touch
them to feel the different temperatures. What do probes and sensors add to
this, in the fifth grade?

<< Using probes and sensors in my classroom has definitely allowed my =
students to develop a deep understanding of heat energy.  The task that =
we completed tested different materials and colors to determine their =
temperatures when exposed to a light source.  However, learning the =
software, the technology, and developing computer skills (my students =
are only in fifth grade) took so long that although this task would have =
normally taken a day or two, the unit took over two weeks! >>
