Predict whether the temperature will be greater at ground or below ground level. Discuss your reasons with your group.
Using the temperature probe, obtain measurements of the ground and air temperatures. Refer to Technical Hints to see how to use the DataLogger software to record temperature for 60 seconds. Record the final temperature on your spreadsheet. . Refer to Technical Hints to see how to transfer data to your spreadsheet.
Push a pencil down into the earth (about 20 centimeters) at the same place that you took a measurement of the ground. Obtain the temperature at the bottom of the hole with the temperature probe. Refer to Technical Hints to see how to use the DataLogger software to record temperature for 30 seconds. Record the final temperature on your spreadsheet. Refer to Technical Hints to see how to transfer data to your spreadsheet.
Repeat the tests at four more locations within your habitat site.
Create a bar chart of the temperature probe readings at and below ground level. See Technical Hints to create a bar chart from your spreadsheet.
