“Don’t know much about science” may be a good description of many students in U.S. public schools, at least if you’re swayed by a new report issued by The Fordham Institute.

The report, The State of State Science Standards 2012, indicates that K-12 science standards of most U.S. states are mediocre at best – with only 13 states getting an A or B and 38 receiving a grade of C or lower.
