ECOLOGY DISRUPTED:  Winter Roads

Generalizing Conclusions to Your Water Supply What do our conclusions about Baltimore mean for our local water supply?

Show the map of New York City’s water supply or your water supply to help students make connections between the conclusions drawn about Baltimore’s water supply to your water supply.

Discussion

Key Idea: Scientific findings can be generalized and applied to other similar situations.

Question:  So you just used evidence to conclude that salt used to keep Baltimore’s roadways clear is entering into its water supply. How can you apply what you just learned to your drinking water supply?
Answers: Our water supply may also have higher levels of salt because important parts of our water supply are near roads that are salted during the winter months.
