Pat Shingleton: "How to Make a Cloud..."
Before we creep into the peppery weather patterns of late May and early June, here’s a suggestion for the teachers. It’s a great time of the year to investigate the different types of clouds, what they are and where they originate. You can Google or Fire Fox a cloud identification chart while charting the daily cloud patterns provides an excellent assignment. You can also make your own cloud. Items needed are an empty, two-liter bottle, hot water, and a match. Pour about an inch of hot, boiling water into the bottle. Light the match, blow it out and drop it into the bottle. Immediately re-cap the bottle and give it a vigorous shake. Here's the last step, squeeze the bottle and release it. When you stop squeezing, the pressure inside the bottle drops and is similar to the drop in atmospheric pressure before a storm. The smoke gives the drops of water a place to land and you’ve made a cloud. The students will enjoy their homemade cloud.
