Cloning and Stem Cells Jeopardy! Waterford Union High School

Rules Each team sends one person per turn. They cannot get help from their team First to “buzz” in gets 15 seconds to answer. If the first person to buzz cannot get the answer, the second team can buzz in. Once they buzz in, they too have 15 seconds. They also cannot get help. You either gain or lose points on each turn. If no team buzzes within 10 seconds, the question ends and the answer is given.
