Amphitheater Middle School will open for a new school year Thursday with several upgrades installed in a $7.2 million bond project.

The bonds were voter-approved in 2007, and are being used to refurbish several schools in the Amphitheater district this year.

Students starting school this week at Amphitheater Middle School will see a new gym and new computer labs, while staff will use a new front office and new teacher work room.

When crews demolished the old gym, they found a time capsule from a previous renovation, according to a news release from the district.

The "tiny wooden box encased in concrete" held a letter about funding for the 1930 school renovation.

"The letter has been replicated and placed on a bronze plaque. It will be on display outside the AMS front office, along with a bronze timeline of the school district," the news release said.

Six new math classrooms were installed during the project, and they contain Smart Boards, touch-screen whiteboards that can also display digital images from a computer.
