This document outlines various activities and projects involving testing and designing with different materials. Activity 1 involves testing types of ice, Activity 2 is hunting for composite materials, Activity 3 tests material strength and stiffness. Activity 4 specifically tests a foam composite. One project involves designing a fishing pole. Another project develops a solar conducting pot by covering an aluminum pot with graphite to increase heat conductivity from solar focusing. The activities explore composites and their benefits over pure materials, and involve predicting material properties and testing hypotheses about composites.
