Think you know you know your science? Recently, several science gurus—Nobel Prize winners, institute heads, teachers and others who spend most of their time thinking about science—were asked, “What is one science question every high school graduate should be able to answer?”
Take their quiz and see how you do

If this quiz wasn’t as easy as you thought it would be, you’re not alone. According to a recent National Science Board survey, 90 percent of Americans are interested in science, but only 15 percent consider themselves well-informed. In high schools, only 60 percent of students complete a general biology class, while only 40 percent complete a general chemistry class and a scant 27 percent complete a physics class, according to the National Center for Education Statistics.
Even if you did learn basic science in school, these questions might be tough to answer, according to O. Roger Anderson, professor of science education at Teachers College at Columbia University.
“People are so deeply involved in their family lives and professions,” Anderson said. “How are they supposed to remember this stuff?”
Raspunsurile am sa le pun intr-un post viitor.. 😛 (asta daca nu cumva, cineva va raspunde meanwhile) 😀
