The Annihilator is a death plunge of a roller coaster that begins by dropping the rider through a wide, fast funnel. It swooshes down a gut-wrenching series of S-curves, flies through a 360-degree loop, slides down a straightaway to another funnel and then -- this is the moment of greatest terror -- free-falls into a basket.
Alas, thrill seekers, you will never ride the Annihilator.
It stands about 4 feet tall and it's made entirely of paper. Only marbles ride the Annihilator, which is intertwined with another paper roller coaster, the Epic Fail, so named because high school teacher Mario Rodriguez seemed unable to test it without having the marble fly off the track.
The Annihilator and the Epic Fail were among the ninth-grade science projects on display recently at the new Da Vinci Science High School in Hawthorne. Beyond the improbability of paper roller coasters, what stood out was the unbridled enthusiasm of the students who built them as an engineering class assignment.
"We learned about potential energy, kinetic energy, velocity and the conservation of energy," said Verann Lambert.
"It starts off with potential energy," said classmate Marianna Correa, "and then once it starts going down, the potential energy begins to turn to kinetic energy. The velocity is how fast it goes, and then the law of conservation of energy is because in the end, you will wind up with the same amount of energy from the top to the bottom . . . but only if it's perfect, no bumps, no friction."
Verann butted in. "Velocity," she said, "equals the square root of the kinetic energy divided by 0.5 times the mass."
Joined by fellow team members Elijah Hernandez and Sandy Sanchez, they seemed capable of talking this way all night.
Da Vinci and its conjoined twin, Da Vinci Design High School, are one vision of the future of education. They trace their lineage to two celebrated charter schools, High Tech High in San Diego and Camino Nuevo High in the Westlake area of Los Angeles. Like Da Vinci, those schools employ a "project-based" curriculum that allows students to learn through hands-on projects, often involving teamwork and computers.
What sets the Da Vinci schools apart is more political than pedagogical. These schools are part of an unusual battle between two overlapping school districts -- one highly successful, the other not.
The Da Vinci schools opened in August, chartered by the tiny Wiseburn School District in an area that encompasses parts of Hawthorne, El Segundo and an unincorporated chunk of L.A. County.
Wiseburn -- established in 1896, according to its website -- is an elementary school district, only allowed to operate traditional elementary and middle schools. Its schools are known for high academic standards and excellent test scores, and for doing something that very few districts anywhere have done -- eliminating the "achievement gap" separating black students from their white and Asian peers.
Students from Dana Middle School are supposed to go on to Hawthorne High School, a low-performing campus that is part of the troubled Centinela Valley Union High School District. Many avoid it by finding a way into neighboring districts or private schools. For years, residents and administrators in Wiseburn have dreamed of establishing their own high school.
To do that, they needed to create a "unified" school district, with elementary, middle and high schools. But a years-long effort sputtered in 2004 when the Centinela Valley district sued Wiseburn, arguing that its petition to expand was invalid because it lacked an environmental impact statement.
Not long after, district officials came up with a new idea: A charter school.
State law allows an elementary district to authorize a charter high school, a public school that operates independent of usual district rules and bureaucracy. And so, at a time when many school districts were fighting charters, which they saw as competition, Wiseburn decided to open one.
So began the Da Vinci schools, run in the buildings that formerly housed Dana Middle, which moved into new quarters next door. Parents and students, by all accounts, have been delighted.
"I love it," said Crystal Brown, whose son Doriyon is a freshman at Da Vinci Science. "I love the diversity. I love the atmosphere. It's great."
Together, the schools have 448 students. The design school offers only ninth grade this year; the science school has ninth and 10th. They will expand by one grade a year.
Matthew Wunder, the former principal of Dana who runs the charters, said they have attracted students from 96 schools in 38 ZIP Codes. The largest contingent -- about 160 -- attended Dana last year. Wiseburn Supt. Tom Johnstone said his district used to send more than 40% of its middle school graduates to Centinela Valley schools, despite "deep, deep dissatisfaction." This year, he said, that figure dropped to just under 8%.
