Student: Why are there even environmental engineers Mrs. Brinza?
Mrs. Brinza: I'm not sure. Why do YOU think there are?
Student: The environment must be pretty important?
Mrs. Brinza: Great question!
Mayor Higgins has recently contacted the fourth graders to help with a problem in his community of Greentown. He notices changes in the ecosystem which include plants and animals such as frogs dying. While his community could have many culprits, he decides to gather some evidence! In fact, he has pH results from 3 years ago that can help. The pH data comes from both water and soil-based sites. Comparing the pH data from 3 years ago to today's pH data will allow us to see any possible differences and lead us to the possible cause of the pollution. Can the fourth graders help Mayor Higgins figure out who caused the pollution? I surely hope so!
