Al 88, Si 12 (wt%), eutectic alloy
This sample is a casting alloy of eutectic composition. From the melt a eutectic is formed between aluminium solid solution and virtually pure silicon. Slow solidification produces a very coarse microstructure. The eutectic comprises large plates of silicon in the aluminium matrix. This microstructure displays poor ductility due to the brittleness of large silicon plates. The microstructure is normally refined through either rapid solidification, which lets the silicon phase assume a fibrous for

Each student will bring in a fabricated artifact from Catlin's life, resulting in a museum exhibit in the class.
NASA KSNN What changes a shadow's size?
Light is a form of energy. It interacts with matter, or the material that makes up an object, in different ways based upon the qualities of that material. Light passes through objects that are transparent. These items appear to be clear. Materials that are translucent let some light pass through, but this light is scattered. These items look milky or fuzzy. Some materials are reflective, or bounce light back. Reflective items are shiny. And objects that are opaque block the light.
