| Small Wonders |
by Michael Wiest and Danny Rolens
Cordell Elementary School, Cordell, Oklahom
(presented at the 1999 Earthstorm Science Fair)
We are Cordell Elementary sixth
graders. Michael's dad told us about thermistors and we decided to demonstrate
how it works using a part of a thermostat.
We
chose this project because we wanted to learn about thermistors and how they
work. Our project is about how temperature is collected at the Mesonet tower
and how a thermistor plays a part in it. A thermistor is a temperature sensitive
device that is very sensitive to small temperature changes. We are showing
how it works by using a household thermostat to show the basic principle of
how temperature can be collected remotely.
We found out about collecting
temperatures at a Mesonet site. Due to remote locations, power was derived
from solar batteries and the amount of available power is limited. Careful
thought has to be given to weather instruments with power consumption in mind.
The thermistor may not be the best device to use, but it is the most efficient
device.
We learned what a thermistor is and how
to build a model of one. We'd like to thank my dad, Rich Wiest. We would do
another project. They are fun and you get to learn about the Mesonet. |
