　　Like other heavily populated nations, India is trying to find new ways to produce more food to feed its ever increasing population. But one of the methods India recently has taken is as old as the Upanishads. It's called simply storing grain. Today in India, they are calling it the“Save Grain Campaign”and it seems to be working.

　　By planning ahead, the country has opened more land and increased grain production from 51 million tons in 1995. India can now depend on its own grain supply. To reduce post-harvest losses, estimated at 9.33 percent of the nation output, the Indian Ministry of Food has taken several steps to let more people know more about scientific methods of grain storage.

　　The“Save Grain Campaign”, a pilot program in 1965, now is gaining popularity. There are 17 campaign offices across India. Campaign workers work closely with provincial governments to teach farmers scientific methods of storing food and pest control.

　　Observations can be made directly and indirectly. For direct observation, instruments are 14 used. Some instruments used by modern scientists are quite simple; others are very 15 .

　　To complete his experiment, the scientist must state his observations in numerical 16 . This means that he has to make measurements. With the results from these he can make more 17 comparisons or descriptions to 18 his hypothesis. The results of a scientific experiment 19 on a valid hypothesis can often 20 a better understanding of the world and the universe.
