âHere comes a fast one,â Skadal said. Students from Napa's Silverado Middle School set up a "speed lab" as part of an 8th grade science project studying motion. Don't worry, they weren't giving out tickets. Jennifer Huffman, Register Signs at the school note a 25 mph speed limit, but many vehicles seemed to be going quite a bit faster. Kashin Adams, 8th grader, said the Speed Lab was one of the first projects heâs been able to do outside this year. âIf I was at home on Zoom, it wouldnât be as much fun.â âItâs easier to learn in person,â said Cassidy Jones, also an 8th grader. âItâs funâ to see the reactions of the drivers once they notice kids recording them during the Speed Lab, she said.
