If you are planning a picnic, watch your pets. If your dog paces and your cat twitches, make other plans. It may rain that day. If you want to wash your car, go outside early in the day and look for a spider. If you see a spider spinning a web, get out your soap and bucket. There will most likely be fair weather.
If you would rather fly a kite, look at the stars the night before. If they are bright, find your kite and string. It will be windy the next day. But if you are more in the mood for a swim, listen to the crickets. By counting their chirps, you can tell if it is warm enough.
What do animals know about weather? Dampness collects in the air before rain. It makes each hair in an animal's fur swell. That is why your pets move about restlessly. Spiders do not like dampness in the air, either. A spiderweb will not stick to a damp surface. So if a spider is spinning a web, the air must be dry.
How can stars help you plan your fun? Stars are most easily seen when winds high in the air blow dust and clouds away. These winds will drop to the ground the next day, making it windy. What about those crickets? Count the number of times a cricket chirps in 15 seconds. Then add 37 to find out how warm it is. If you hear 35 chirps, it is 72 degrees.
