Day 6: How are Milk Cartons Made?
1) Video: How are milk cartons made? This is a 7 min video showing the steps from tree to filled milk carton, very interesting.
Recap: Cartons are made of paper with a special plastic liner, both the paper and the plastic liner are recyclable. Cartons are pressed into a bail and then go to the pulp mill. There they are ground up (pulped) and new paper products can be made from that pulp.
2) ELA: What are landfills? And why are landfills a problem? What material is found mainly in landfills? (Paper) What material is paper made off? (trees) Is it a lot of work to make a carton? Why?
What is easier….making products out of trees or out of recycled paper pulp?
3) Social Studies: Make your own paper from milk cartons from the lunchroom. Here is a short video to show you.
Think about it : How much work did it take so that you can drink your milk from a carton today. Is there a better way?
