An important factor in our weather is the difference in temperature of the air. A good example of this relationship is the production of land and sea breezes along the coast of an ocean. These winds occur because of the difference of the temperature of the air above the ocean compared to the air above the land. Another example comes from understanding the formation of some clouds. The air next to different patches of ground heats up differently. Air next to hot land surfaces becomes warmer, which causes it to rise, expand, and cool to form cumulus clouds. In this experiment you will investigate local changes in air temperature over a 23-hour period. You will do this with two temperature probes—one near the ground and the other positioned 1 m above the ground.


  • Use temperature probes to collect and analyze air temperature measurements for 23 hours.
  • Collect and analyze air temperature measurements at different heights above the ground.
