Throughout the daylight hours the sun heats up the air and the soil. Project 1 in this manual investigates the changes in air temperature during this process. It also investigates the changes in temperature during the nighttime hours. In this experiment you will perform a similar investigation, however you will investigate the changes in soil temperatures, at different depths in the ground.


In this experiment, you will

  • Use Temperature Probes to collect and analyze ground temperature measurements for 23 hours.
  • Collect temperature measurements at different depths in the ground, 1 cm below the surface and 10 cm below the surface.
