We all know that foods will easily go bad if they get too warm. So we usually put them into our fridges to keep cool in hot weather. But can you make it without fridges?
In 1995, Abba, a teacher from Nigeria, found a cool way. His invention was called Pot-in-Pot Cooling System.
It uses two clay pots (陶罐). There is a smaller pot inside a larger one. The space between the two pots is filled with wet sand. Fruit, vegetables or drinks can be put into the smaller pot. A wet cloth covers the whole cooling system. Some foods can be kept fresh for several weeks in it.
Abba built five thousand pot-in-pot systems for the villagers in his hometown. Then people all over the country began using the invention. Soon it became popular with farmers in other African countries.
In 2000, Abba got a prize --- the Rolex Award. If you are trying to do something to improve human life, you may have the chance to get this prize.

Do you know something about tree rings? Do you know they can tell us what the weather was like, sometimes even hundreds of years ago?
A tree will grow well in a climate with lots of sunshine and rainfall. And little sunshine or rainfall will limit the growth of trees by studying the tree rings. For example, to find out the weather of ten years ago, count the rings of a tree from the outside to the inside. If the tenth ring is far from the eleventh ring, then we’re sure that it was sunny and rainy most of that year. If it is near to the eleventh ring, then the climate that year was bad.
Tree rings are important not only for studying the history of weather but also for studying the history of man. Many centuries ago, there lived a lot of people at a place in New Mexico. But now you can find only sand there-no trees and no people. What happened?
A scientist studied the rings of dead trees there. He found that the people had to leave because they had cut down all the trees to make fires and buildings. As all the trees had gone, the people there had to move.
