Acid Rain Continued...

After collecting our data on the pH of the bodies of water in the Gray Area, this week students focused on making sense of the numbers.  They looked at the "Acid Rain Files" a collection of research and evidence about the problem and looked at the statements of the factory owners in the area.  Students came to the conclusion that limestone is neutralizing most of the acid rain, but the high acidity of one particular granite-based river could still be the problem for fish.

We also broke ground on our expert card project for our field study and did some group analysis of our Listening to Crickets reading.
