A kindergarten teacher is responsible for planning the curriculum for each day and for the collective school year. Teachers must allow the children to observe an activity while also giving them the opportunity to ask questions and look for the answers. Instructions need to be very precise yet easy to understand.
The CS220 is a thermocouple that measures the temperature of a surface by direct contact. SI-111 Infrared Radiometer with Standard Field of View. The SI-111, manufactured by Apogee, is a precision infrared radiometer that determines the surface temperature of an object without physical contact.
Remember that surface temperature is different then ambient air temperature and must be measured with a surface thermometer to decide whether the surface is high enough above the dew point to allow you to paint. For example a steel hull will be cooler on the shady side compared to the sunny side.
