Sara does every fast, very fast.  The drawback is she got her assignment wrong, she messed up her shirt after eating, and she did not tie her shoes correctly for soccer practice. One day, after she built  a soapbox derby racer and it then fell apart, she surfed the Internet, learned about friction, then applied her science skills to conduct two experiments-the bike race and the swim race.  Using what she discovered from the experiments, on her big day, the day of the soapbox derby, she slowed down, and ...won the race!
