The student will be able to:
1) define reflection.
2) observe and compare the angle of incidence with the angle of
3) find the number of images reflected by two mirrors when the mirrors
are placed at different angles.
4) demonstrate reflection of light using a kaleidoscope.
5) illustrate how multiple images can be produced with a particular
Paper, rulers, small mirrors, protractors, small object (e.g. beads,
coins), plastic strips, clear contact paper, sequins, beads, duct tape,
1) Students draw a broken line on a piece of paper, next a straight
line is drawn extending from the broken line at any angle. A small
mirror is set upright at the point where the two lines meet. Students
then turn the mirror until the reflection of the dotted line is in line
with the real dotted line. Next students line up a ruler with the
reflection of the straight line in the mirror. The reflection of the
straight line in the mirror is extended and drawn on the paper. Next
the angle of each side of the broken line is measured with a
2) Students use two mirrors, a protractor and an object to find out how
many images are formed when the two mirrors are placed at different
3) Students construct a kaleidoscope using three plastic strips taped
into a triangle with duct tape. In between two clear contact circles
are put a few sequins and beads. This circle is looked at through
the plastic triangle strips.
