NASCAR race cars are made up of many different parts, and these parts are made of many different materials. Students first classify everyday objects based on the objects’ observable properties. After noticing that the objects can be grouped by the materials from which they are made, students sort the objects again. Next, they investigate how different materials can be formed into some shapes, but not others, and make claims about how the ability to be formed into certain shapes (structures) is what helps determine what that material can be used for (function). What can a NASCAR engineer use instead of glass for a windshield? Ask a second-grade student!
