LAKEWOOD, Colo. -

Denver-area high school students who won Katy Perry's lip-dub school spirit contest are donating more than $9,000 to help Coloradans affected by disasters, including September's floods.

Students at Lakewood High School will present a check to the American Red Cross during a rally Tuesday morning.

A video featuring more than 2,000 students lip-syncing to Perry's "Roar" won the school a free concert in October. The students challenged high schools across the country to raise $1,000 each for a charity of their choice.

The Lakewood students raised money by selling merchandise and collecting donations.
