AIChE K-12 Module, Grades 6-8 (1) - Exploring Bioproducts: Glue for Piñatas

This module introduces students to bioproducts. Students learn about different examples of bioproducts made from different plants. Students also get to use a bioproduct. Students watch a demonstration of making “engrudo” (wheat paste), which is made from starch and hot water and involves the chemical reaction of gelatinization. The “engrudo” is a bioproduct and a starch glue. Starch glues have been used throughout history and still used today, primarily in the packaging industry. Students use the “engrudo” to make a piñata. Students will not only learn about new science vocabulary and processes but also about history and culture involving bioproducts.
