FrogPond Lab Report • Scenario #:

• Frequency of deformed frogs in top/bottom pond (show

calculations):

• Question 1: Is there a higher (or lower) frequency of deformed frogs in Top Pond than in Bottom Pond? How confident are you that your answer is correct?

• Question 2: If there is a difference in the frequency of deformed frogs in Top Pond versus Bottom Pond, what is its cause? – Hypothesis: – Experimental Design: – Results (provide detailed results in table/text form): – Discussion:
