Complete the Worksheet on the different metals. We will give you the volume of material you will need for your bike. You will need to research the density and calculate the mass and price. (Note that steel is an alloy of iron and carbon. It is mostly iron, so you can use the density of iron in your calculations.)

To find the density you can use a textbook or go to an on–line periodic table

Check out these sites developed by the Exploratorium to find out more about the different materials used to make bikes: Bike metals, Bike frame information

After doing that, write a one–page essay explaining what material you will use for you bike and explain why.
