Metals are amazing, and they are all around us. You can probably easily identify them by their shiny surfaces and tinny sound when you tap them. We use metals to run electricity through our house, manufacture our cars, and create circuits for our phones. However, most metals in their pure form are less than perfect for these jobs. Luckily, the properties of metals can be manipulated to make them more useful by adding other elements to form a mixture. These mixtures are called alloys. In this activity, you will look at two types of alloys and their properties.
