Identifying Material Based on Density

[AKG]

My sister has an experiment where she's found the densities of 3 woods and 2 metals, and is asked to identify the materials based on these calculations. Does anyone know of any good links to tables that has various woods and metals and their densities. I have a table of properties of various woods, but the densities she found don't exactly show up on the table. Thanks. In case you happen to know off-hand, or if it helps finding an appropriate table, the values are:

Wood A : 0.646 g/cm³
Wood B : 0.178 g/cm³
Wood C : 0.634 g/cm³
Light Metal : 2.95 g/cm³
Dark Metal : 8.48333... g/cm³

But you have to convert to the US/Brit measurement (imperial).

Hope this helps
