Teacher Info!


Pictured are  the parts needed for students to construct a periscope.
They may come up with different looking items, but the concept of two
triangles with a reflective material, placed in opposite directions of each
other, and encased in a covering will produce the periscope.

Students need to gain the knowledge that it takes light to make reflection
happen.  That light will travel in a straight line unless interupted by a
solid object.
