You should start to see a cloud form! As the cloud gets bigger, it will be easier to see. Look into your jar from the open side (so that the black paper makes a background at the back of the jar) and watch what happens.ħ. Quickly cover the jar with the container of ice.Ħ. Have an adult light a match and hold it inside the jar for a few seconds and then drop it into the water.ĥ. Fill the metal bowl or tray with ice cubes.Ĥ. Add about two inches of warm water to the jar.ģ. Cut the black paper to fit halfway around the jar, leaving about one inch of space at the bottom of the jar.
small metal bowl or a metal baking sheet (should completely cover the opening of the jar)ġ. Sometimes the droplets freeze before they get to the ground and become hail, sleet, or snow!ĭid you know you can make a cloud? It will be much smaller than the ones in the sky that bring us rain, but it forms in the same way as those in the sky. When water drops fall from clouds, it is called rain. When enough droplets stick together in the clouds, they become large and heavy and are pulled down towards the earth by the force of gravity. Then, droplets of water start to stick together as clouds. As the water vapor rises up in the air, it condenses, or starts to cool down and turns back into a liquid. Water from rivers, lakes, streams, or oceans evaporates into the air when it is heated up by the sun. This is exactly how clouds form and make rain. If you left this project taped to your window for long enough, all of the water from inside the cup should eventually end up in the bottom of the bag! When several droplets of water stuck together, they became heavy enough to pull each other down the sides of the bag. The water vapor turned back into a liquid and little drops of water formed on the inside of the bag-this is called condensation. You can’t see water vapor, but you can see what happened next. What Happened:Īs the sun heated up the water in the cup, some of the water evaporatedinto a gas called water vapor. Check your cup and bag throughout the day and watch what happens. Tap the bag with the cup inside to a window where a lot of sun comes in.Ĥ. #SITTING ON CLOUDS SAFE ZIP#
Carefully set the cup inside the plastic bag and zip it closed.ģ.

Fill the cup about 1/4 full with water.Ģ.
plastic zip-top bag (large enough to hold the cup standing up)ġ. In this experiment, you will see how water from the ground gets into the air to form clouds and then falls back to the ground as rain! What You Need:
