New Rochelle Trinity STEAM 5th Graders learning about Aluminum Foil : The Cost Of Convenience

Aluminum foil, wonder of wonder, it wraps sandwiches, and keeps food hot or cold. But what does it actually  take to make aluminum foil?

New Rochelle Trinity 5th grade STEAM students have recently learned all about it, and they all agreed that the cost of convenience for aluminum foil is WAY too high.

Picture1Aluminum does not exist in its free form in nature, instead Alumina silica is found in Bauxite. This ore is mainly found in thin layers in the tropics.

To get it, trees and soil are removed and the bauxite containing soil is mined and crushed. Sodium Hydroxide is added to dissolve the Alumina silica which is then smeltered to remove the last oxygen to become Aluminum.

Is our convenience worth the environmental destruction that Bauxite mining causes? And the failed clean up by mining companies when the mineral is exhausted?

I think not!
