14. Place the thermometer into the soil suspension for about 1 minute. At the end of 1 minute, remove the thermometer from the suspension, read the temperature, and record the result on the Particle-Size Distribution Data Work Sheet.

Thermometer reading

15. Take another hydrometer reading in the undisturbed cylinder at 12 minutes. Place the hydrometer carefully in the suspension about 30 seconds before making the reading to allow it to settle.

Clock reading 10:17

Hydrometer reading

16. Take and record another temperature reading for the suspension.

17. Rinse the hydrometer and thermometer off when they have been removed from the suspension and dry them.

18. Record these results on the Particle-Size Distribution Data Work Sheet.
