In one experiment, Piaget handed children a weight at the end of a string and asked them to find out what determines the speed of the pendulum's swing. As he watched and asked questions, he found that the children were spontaneously considering all the possible variations: changing the weight, letting it drop from increasing heights, giving it stronger shoves, or changing the length of the string...

Poring over the "wrong" answers that children regularly gave on the tests, Piaget was surprised to see that the responses fell into patterns that differed according to the children's ages...
...unreported electrocutions in hospitals; doctors have estimated, he said, that anywhere from 1,200 to 12,000 patients per year are electrocuted. Official safety regulations, where they do exist, are often loosely enforced. Last month the Department of Transportation announced that one-quarter of the tires that it has tested this year failed to meet a significant test: standards originally devised...
