Sonoma Raceway invites kids to combine the fun of racing and learning with its popular gravity-powered car races at the North Bay Science Discovery Day at the Sonoma County Fairgrounds in Santa Rosa on Saturday, October 24.

The raceway, in partnership with The Children's Museum of Sonoma County and Kid Scoop News, will host a booth at the Discovery Day event. All students are encouraged to participate by building their own gravity-powered car from all-recyclable materials, donated by The Children's Museum of Sonoma County. These materials include egg cartons, plastic water bottles, bottle caps, pipe cleaner and much more. Students can then test out their cars on the Sonoma Raceway ramp.

Sonoma Raceway, Kid Scoop News and Friedman's Home Improvement have teamed up the last two years on a gravity-powered car challenge at North Bay schools. Ten schools have participated in the program, which encourages students to get a hands-on experience with science, technology, engineering and mathematics (STEM) as they relate to motorsports. The final round of the challenge takes place at the raceway's annual NASCAR Sprint Cup Series event.

North Bay Science Discovery Day is part of the 10-day Bay Area Science Festival. The festival events are divided up by regions: North Bay, East Bay, South Bay and San Francisco. Admission is FREE for all to attend and events run from 10:30 am - 4:00 p.m. For more information on the Bay Area Science Festival, visit
