Grade 8: Week of October 17th to 21st

Last week's inquiry into water health was very successful! Students examined four different types of water and decided which one was the healthiest based on health indicator evidence. We watched two videos on China: one on Linfen, one of the dirtiest cities in the world, and water pollution. We used this case study to apply our indicators of water health.

This week we are examining human impact on both freshwater and oceans. We will look at case studies such as the diminished supply of cod in Canada, the oil spill in the Gulf of Mexico and the bio-accumulation of mercury and dioxins in our bodies up the food chain. We will model the waste treatment process of flocculation, filtration, and disinfection. Students will receive a review sheet Thursday or Friday to prepare for a test Tuesday October 25th.
