IV. Read the passage and answer the questions with complete sentences. (2 points each)

A team of scientists did an experiment to try to find out the effect that fluorinated water had on tooth decay. The dentists divided a large group of people into 4 different groups. Group 1 was given 10% fluorinated water. Group 2 was given 20% fluorinated water. Group 3 was given 30% fluorinated water. A 4th group was given unfluorinated water. The dentists expected the group that was given 10% fluorinated water to have the least number of cavities. The teeth of all groups were examined before and after the 12 week experiment. The results were as follows:

10 % fluorinated water group 3 cavities 20 % fluorinated water group 1 cavity 30 % fluorinated water group 5 cavities Unfluorinated water group 9 cavities

1. What might be a suitable title for this experiment?

2. What was the manipulative variable in this experiment?

3. What was the responding variable in this experiment?

4. What was the purpose of the unfluorinated water group in this experiment?

5. What conclusion can be made in this experiment?
