Grade 8: November 29 - December 3

This week grade 8s will learn how humans affect the hydrosphere both negatively and positively. We began our unit with "the river that caught on fire" and are examining factors that affect water's health: turbidity, biological indicators, nitrates, phosphorus, temperature, and dissolved oxygen. We will examine and model how water is cleaned. We will examine different types of pollution (point and non-point pollution), and various case studies from USA to China. This is our last unit studying the hydrosphere. In total, the hydrosphere counts for 30% of all EOG questions. Please see your child's test included with the progress report Tuesday November 30th.
