LOS ANGELES - When the space shuttle Endeavour hits the streets of Los Angeles, some schools along the 12-mile route are using the historic move as a teaching moment.

Retired laser scientist Hal Walker runs an after-school tutoring center and reminded his kids about the contributions of minorities in the shuttle program.

After sitting at an airport hangar for the past three weeks, Endeavour is set to roll out before dawn Friday on a two-day journey to the California Science Center where it will be put on display.

A charter elementary school planned to take students on a field trip to see the shuttle, which will be temporarily stationed at a parking lot as crews re-route power lines ahead of the route.
