Smithsonian X 3D (SIx3D) offers a neat way for students to learn about artifacts from the Smithsonian museums. The site is the result of a collaboration between Autodesk and the Smithsonian Institution. More than artifacts are currently featured on Smithsonian X 3D. The artifacts can be viewed as 3D models that you can virtually manipulate. Many of the artifacts have accompanying fact sheets through which you can learn about the artifact's history and significance. A screenshot of the fact sheet accompanying the model of the Philadelphia (a gunboat) is included below.
If you have access to a 3D printer you can print models of many of the artifacts featured on Smithsonian X 3D.
