3.2.2   recognize that light can travel through certain materials and not others (transparent, translucent, opaque).

3.2.3  identify ways to generate heat (friction, burning, incandescent light bulb)

3.2.4  demonstrate that heat can flow from one object to another by conduction.

3.2.5  identify materials that act as thermal conductors or insulators.

3.2.6  recognize how sound is produced when objects vibrate.
