Practice making careful observations. Choose something living to observe, either outdoors or indoors. If you’re observing your puppy playing in your backyard, you must not only record the puppy’s actions, but the time of day, the weather, the sounds around you, who else is there, etc. All of these things are important, and should anything surprising happen, it becomes very helpful to have all the information. For example, if you don’t record that a thunderstorm is approaching, and you just say "the puppy suddenly stopped chasing the stick and hid under a bush," you are not recording all of the information. So use all your senses and record carefully and thoroughly. Be sure to be objective. Instead of saying "my puppy kept jumping up happily," you should say "my puppy jumped 15 cm off the ground 6 times, wagging his tail." That way the reader decides if he is happy or not! A record of at least 25 observations should be made.
