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.

Cells & Stuff
• This is what happens to telomeres as cells age• They shorten
Cells & Stuff
