Here are a few pictures of both classes filtering "hazards" from water. Each group had the task of building a filter with limited materials. Their ultimate goal was to separate the 'hazard' from the water in the hopes of being drinkable.
Here is the redesign of a filter to clean hazards from water. This rebuild shows the filter layers that the class came up with. (Plus they filtered the water a few times to get to almost drinkable.)
City Lore Dance Residency
Take a look at Class 4-214 participating in authentic Indian Dance that they learned with City Lore. They did a wonderful job!
