Today in Room 10 we investigated how it rains!!
Things you need:

• glass jar
• plate
• hot water (ask an adult to help with this bit)
• ice cubes

Directions
Pour about two inches of very hot water into the glass jar.

Cover the jar with the plate and wait a few minutes before you start the next step.

Put the ice cubes on the plate.

Explanation
What happens? The cold plate causes the moisture in the warm air, which is inside the jar to condense and form water droplets. This is the same thing that happens in the atmosphere. Warm, moist air rises and meets colder air high in the atmosphere. The water vapor condenses and forms precipitation (Stuff that falls from the sky) that falls to the ground.
