INCLUDES ONE PAPERBACK STORYBOOK

Everywhere around us, earth materials like pebbles, soil, sand, and silt are used in human creations. What properties make an earth material useful? Different materials have different properties, making them appropriate for different uses. Students learn how materials were combined to create the Great Wall of China and explore which earth materials make the strongest, sturdiest wall and mortar. For the design challenge, students construct their own "mini wall of China."
