These seven applications make student PDAs a powerhouse of a reference tool. Four conversion tools make difficult length, mass, capacity, and temperature translations a cinch. Liters to gallons, miles to kilometers -- kids can learn precisely how these compare in concrete, visual terms. There's a digital/analog time reference feature, a multi-use stopwatch application that is ideal for timing experiments, and a cursive writing reference that lets students write on-screen and improve their penmanship skills.
