As National State Teacher of the Year, Sandra received $10,000 from Citibank, a proclamation from the Governor of Guam, and a citation from the U.S. Congress, which was entered into the Congressional Record.  President Clinton  honored her at a White House recognition ceremony in the Oval Office where she received a Presidential Commendation Letter and later that evening was a guest at a black tie dinner. Sandra was then sent to International Space Camp to train in space science along with 54 teachers from the U.S. and twenty foreign countries. An outcome of this training is Mrs. Hart’s mock space shuttle cabin, which she constructed and when inflated holds approximately 28 children. The shuttle is used as a prop in her one-and-a-half-hour chemistry/ physics interactive space show titled, "Space, Science and Other Things," that she performs for children of all ages and cultures. The show demonstrates simple chemistry and physics experiments using household products along with music, magic, fire, screaming, yelling, candy, aliens and lots of fun. Another product of the show is the publication of her book, Space, Science & Other Things – Elementary (K-8) Interactive Space Show, which details her show for other teachers to perform.

In 1999 she was selected as the Department of Defense Teacher of the Year, Guam District. This resulted in her being one of the honored guests at the 1999 Department of Defense Assistant Principal’s Conference held in Tokyo, Japan. Later she was selected to attend the 1999 DoD Far East Technology Conference also held in Tokyo. As a committee member of the DoD Professional Development Institute III, she was sent to the 1996 and 1999 National Education Forum in Washington, D.C. to meet with the Secretary of Education and various educational leaders for the Goals 2000 Program.

She is married to Colonel Michael C. Hart, (ret) USAF. She has two sons, James and Michael Bojtos.
