Experiment No. 1 Making Rain Experiment
Materials:
 Glass Jar
 Water
 2-4 Ice Cubes
 Metal Lid or Piece of Foil



Matches/hairspray
Container to heat up water
Electric kettle/stove
Safety Precautions: Handle hot materials by using gloves and grabbing cool container handles. Hot water splash injuries
can be minimized by wearing protective eye gear, lab coats, and long sleeves. DON’T SPLASH YOUR CLASSMATES
WITH HOT WATER.
Procedures:
1. Fill up the ziplock baggie with ice cubes, or if using aluminum foil, fold the aluminum foil so that it has shallow
walls. It needs to be big enough to cover the entire opening of the jar.
2. Fill the large jar about ⅔ to ¾ full of hot water. The hot water warms the inside of the jar which is similar to the
warm air that is needed when clouds form in nature
3. Next, using oven mitts/towels, empty the water from the jar until there is only about ¼ left in the jar. We are filling
it up and then emptying it because this minimizes large temperature differences in the jar that could cause the
glass to break.
4. Strike the match and drop it into the jar. The water will extinguish the flame and a small amount of smoke will rise
from the surface of the water. Or, if you have hairspray, spray some towards the surface of the water. The reason
why you need matches or hairspray in this experiment is because the little droplets of water that evaporate need
dust or particles to grab onto so when they float up to the atmosphere they can condense to form a cloud.
5. Quickly place the ziplock baggie of ice or aluminum foil with the ice over the top of the jar.
6. Now wait and observe a cloud forming in the jar. If you look closely you should see the warm moist air condensing
and swirling in the area near the top of the jar where it comes in contact with the ice.
7. If you wait long enough, you will also see precipitation inside the jar as the water droplets become so large they
drip from the cloud that has formed.
8. When your cloud has formed, remove the ziplock baggie of ice or aluminum foil with ice and watch the cloud
come out of your jar.

Experiment No. 1 Making Rain Experiment
1. Draw an illustration and add labels for each part.
2. Then describe what you observed in words.
QUESTIONS:
1. What are clouds made of?
2. Draw a picture showing a water droplet forming on a condensation nuclei. Add labels.
3. Would a cloud form in our jar if we didn't add the match? Explain.
4. Why was the fog in the jar moving down away from the cover? Explain.
5. In science, models are used to represent real-life events. How is this cloud demonstration similar to how
clouds form in real life?
