Perhaps this indicates that stronger efforts need to be made to educate young children about the effects of drugs and ways to prevent drug abuse. Second, children's knowledge about drugs did not appear to be influenced by their parents' drug use. Perhaps children were around other people who used drugs or had seen pictures of drug use on television or in movies and advertisements. Finally, this study shows that many young children do know about the existence of drugs, especially tobacco and alcohol. Therefore, these data suggest that it is never to early to discuss the dangers of drugs.
Animals have some amazing senses.
Dogs, cats and mice can hear high frequency sounds that people cannot hear. Elephants can hear low frequency sounds that people cannot hear. These animals all use their ears to hear. Scientists studied a particular butterfly that lives on an island in Panama. Using an electron microscope, scientists located a very thin eardrum on the wings of the butterfly.
