SYMMETRY OF MATTER 
PHYSICAL
SCIENCES – SYMMETRY OF MATTER
Objective: Students learn to recognize symmetry.
Materials:
View Thru Geometric Solids Getting into Solids (Pyramids) optional
Teacher Notes:
There are many web sites with animations of different forms. They might help you explain symmetry to your students. If you purchase a set, you might want to use them for the questions on overall symmetry and rotational symmetry.
