The student should be able to describe how reflective symmetry is present in nature. Compare it to rotation and reflection. To find out, experiment with a hand-held mirror while standing in front of a mirror. If so, point out the line of symmetry. Compare symmetrical and non-symmetrical designs.
Further Activities Bring in many examples of reflective symmetry.
Have students find the line or lines of symmetry. Have students experiment with mirrors to create symmetrical designs. Ask them to try to re-create the design on paper. Find examples of mirror symmetry in nature. List or sketch them.
