  1. Geometric Analysis of Suction Feeding

  2. Math & Nature • The universe is written in the language of mathematics • Galileo Galilei, 1623 • Quantitative analysis of natural phenomena is at the heart of scientific inquiry • Nature provides a tangible context for mathematics instruction

  3. The Importance of Context • Context • The part of a text or statement that surrounds a particular word or passage and determines its meaning. • The circumstances in which an event occurs; a setting.

  4. The Importance of Context • Context-Specific Learning • Facilitates experiential and associative learning • Demonstration, activation, application, task-centered, and integration principles (Merrill 2002) • Facilitates generalization of principles to other contexts

  5. Math & Nature • Geometry & Biology • Biological structures vary greatly in geometry and therefore represent a platform for geometric education • Geometric variability  functional variability  ecological variability • Mechanism for illustrating the consequences of geometry
