What better way to learn about Chemical changes (changes that are irreversible) than to watch good milk go bad after about 3 weeks sitting on a shelf?
The smell is HORRENDOUS but it effectively proves that a chemical change did take place by turning the liquid into a solid (lumps). The milk cannot go back to being good. That change is IRREVERSIBLE!!!!
