Colourful Solutions: Chemical Engineering Dyes to Brighten Lives

Students will learn to think like chemical engineers as they delve into the dye technologies that allow us to express ourselves through colourful clothing. They will read and discuss complex texts, analyse concept maps and graphs, and develop an appreciation for indigenous (Māori) dye technology.

Lesson 3

Future Foods: Can we reduce the carbon footprint of our favorite meals?
Food and climate are deeply connected. Students will dig into data to discover how our food choices impact greenhouse gas emissions. They will propose solutions to reduce their carbon “foodprint,” both as current consumers and as future food engineers. Students will eat this up in class and savor it for years to come!

Lesson 4
The Science of Craft: Building New Materials with Old Techniques
STEM is older and more expansive than you might imagine. Crafted materials, like knit sweaters and woven baskets, were our ancestors’ solutions to everyday problems. In this lesson, we learn the geometry and physics of traditional crafts, and explore how these technologies help us engineer new solutions for the future!
