When the left leg of junior forward Brooke Yarsinsky cramped up during Cherokee's field hockey game against Camden Catholic last week, teammate and senior forward Jessica Havers went immediately to her side. This came as no surprise. The two, close friends, have been there for each other throughout their two years of playing field hockey together. "It's nice to have someone that's always there for me," Yarsinsky said. "I know I can always count on her on and off the field. " The undeniable chemistry began long before field hockey.

For at least six girls on the Williamstown field hockey team, there's always someone special on the field they can count on. With three sets of sisters playing for the Braves - Allie and Jamie Trimble, Kamryn and Kate McKinney, and Gloria and Deborah Adebowale - the team dynamic and chemistry on the field have been an incredible sight for coach Kellyn Riley in her first year with the team. "It's nice to see them develop and push each other," Riley said. "The younger siblings kind of look up to the older siblings.

Under the rapt stares of about 100 children and a statue of Benjamin Franklin, a staff member at the Franklin Institute poured liquid nitrogen into a bucket of water. A cloud mushroomed out over the sides and raced toward the youngsters. "Wow!" a chorus of surprised and delighted children squealed, reaching out to touch the indoor cloud. A few hundred more children scurried through the institute's famous heart and new brain exhibits Saturday, when the museum opened to more than 1,400 people free of charge.

Quick! Calculate the half-life of a radioactive isotope, given a series of Geiger counter readings. Name a hydrocarbon based on its number of carbon atoms and a description of the chemical bonds. Spit out the number of neutrons in an isotope of tungsten. Tricky for most adults whose high school chemistry class was long ago. But what about Audrey Gallier, who has yet to take it? Easy as evaporating water, apparently. At the Kimmel Center for the Performing Arts on Monday, the 12-year-old from Brookfield, Ill., correctly answered brain-buster after brain-buster to win the national You Be The Chemist Challenge, a chemistry-quiz contest for grades five through eight.

THE UNION cannot seem to find its groove at home this season. It has won only once at PPL Park, and the Sons of Ben voiced their displeasure during the previous two home games. Fortunately for the Union, it will not even play on the East Coast for about 2 weeks. They play the Galaxy at Los Angeles on Sunday and Chivas USA at suburban Carson the following Saturday. The team will stay in LA in between games, because it makes sense logistically. "We take this as an opportunity," manager John Hackworth said.
