Lab: An Environmental Impact Study Mark as Favorite (7 Favorites)
In this lab, students will test a water sample which comes from a local zoo, where, it is reported that many bird eggs are not hatching.

Students will also conduct a serial dilution to determine the concentration, or molarity, of the ion in the water sample. This molarity will be compared to known values to determine if the materials in the water are at an unhealthy level.
