Plastic, metal, wood, and stone. We encounter many different materials every day. Each object around us is made of a specific material. Why are they not all made from the same material? The answer is that every material has different properties; some are hard and others are soft, some are transparent and others are opaque. For each product that is produced, the material from which it is made determines many of its properties. This is why material testing is so important. These tests allow… Read more

Bridges are made of many different materials: steel, stone, wood and even rope. How do engineers decide which materials to use? In this activity, your students will learn about material properties, test the strength and flexibility of several materials, and use their test information to predict which material will result in the strongest bridge. They will test their hypotheses by buiding simple bridges from each material and determining which bridge can hold the most weight. Read more
