But the total lack of games tailored to girls could be providing boys with an academic advantage over their female counterparts.

Would you like to measure the rate of a dripping faucet, but lack the sophisticated equipment required? Do not despair! Armed with a gallon jug and a stopwatch, I have prepared an easy-to-use water-flow estimation guide.
