Product Details

Dew point and relative humidity—two very important terms that influence weather conditions. Students will make direct dew point observation and sling psychrometer dew point measurements, perform a relative humidity calculation and obtain a sling psychrometer relative humidity measurement. The different measurement techniques will then be compared and contrasted. Kit includes materials for 15 sling psychrometers, 15 dew point metal cans, detailed teacher notes and student instructions and data sheets.


Materials Included in Kit: 
Black rubber cap, ½" diameter, 15
Cotton wick, flat, ¼", 2
Metal can, round, ½ pint, 15
Pipet, Beral-type, thin stem, 15
PVC, ½" diameter, 6" long, ⅛" hole in end, 15
Rubber bands, small, 300
Screw, #6 x ¾", 15
Thermometers, plastic-backed, 45

Performance Expectations

HS-PS1-1: Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms.
HS-PS1-2: Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-5: Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
HS-PS1-8: Develop models to illustrate the changes in the composition of the nucleus of the atom and the energy released during the processes of fission, fusion, and radioactive decay.
