Do this activity on condensation. You will need: • empty bottle (with a medium or small opening) made of clear glass
• hot water
• ice cube
Follow these steps:
A. Place some hot water in the bottom of the bottle and put the ice cube over the opening of the
bottle so that it rests on top and drips into the bottle.
B. Observe carefully what happens over the next 15 minutes. Make a sketch of your experiment
and write down your observations.
Explain your observations using the terms:
• condensation
• evaporation
• solid
• liquid
• gas
