Additional Prerequisites

• Teachers and students may create a free account for unlimited access to the materials.
• The two videos linked in the handout may have ads that play at the beginning.
  

Differentiation

• As an extension, lead a classroom discussion on the cause and effects of the Flint Water crisis and have students come up with preventative measures that other municipalities can follow to avoid similar issues.
• Due to Flint's population being mostly African American, the videos could support a discussion about historical racism in America, systemic racism, and environmental racism.
• Less advanced students may benefit from this lesson by completing the first 6 problems, with questions 7-9 done as a class.
  
• Science and engineering classes could connect this resource to lessons about the scientific method, confidence intervals, chemical reactions, water quality measurements, and the health effects of toxins in the water, air, and soil.
