Investigating Materials for Sails

The girls investigated the different properties of materials that they will be using to build their sails.  While separated into small groups, the girls got a chance to manipulate the different materials.  Some of the materials were: aluminum foil, felt, tissue paper and wax paper.  As a class we listed the properties of each material.  The girls did a great job of describing the different characteristics of the materials.  Your daughters are mechanical engineers in the making!
