A program in the United States brings scientists and engineers into elementary schools to teach teachers more about how to teach science.
DAVE WEISS: "Welcome to science class. So good to see you guys today."
Dave Weiss is a retired engineer. One day each week he volunteers at Georgian Forest Elementary School in Silver Spring, Maryland, near Washington.
DAVE WEISS: "But the experiment we're going to do, we want to keep all of ourvariablesconstant."
He works with teacher Fred Tenyke on science projects for ten-year-olds.
DAVE WEISS: "Fred is so enthusiastic and he's so much fun with the kids. I can see that he really loves what he's doing. I get as much pleasure from helping the teachers as I do helping the students."
