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.
