In this lab experience, students carry out an investigation to determine how much particulate material is in the air. They also observe the effects pollution can have on water and building materials. After completing this investigation students will gain a better understanding of how human activity has added other substances into the atmosphere, creating an imbalance and causing the quality of air to degrade.
Safety:
Before conducting the lab, review the safety precautions on the student page with the class. Then discuss any safety precautions that are specific to your science laboratory or classroom.
