These supplies are needed: • shiny metal can
• ice cubes
• water
• thermometer
• stir rod or spoon
Follow these steps:
1. Record the temperature of the air.
2.Fill a shiny metal can with water at room temperature.
3. Slowly
add ice to the water and stir gently with stir rod or spoon. Continue to add ice until a film
of water appears on the surface of the metal can.
4.Record the temperature when the dew develops on the can.
5.Repeat this experiment to confirm the data.
Write a scientific summary of your findings. Include your hypothesis, data, observations, and conclusion. Be
sure to answers the questions below in your report as well as explaining your method and results.
Why must the metal can be shiny?
Why must the ice be added slowly?
What advantages would be in repeating the experiment several times?
What is the average dew point?
If possible, compare your findings with someone else who did the experiment. How are your results similar or
different, and why?
What did you find out from this investigation? Be thoughtful in your answer.
