Cloning and Stem Cells Jeopardy !

1. Cloning and Stem Cells Jeopardy! Waterford Union High School

2. 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.
