Topics: Misconceptions, Polyhedron, Euler's Formula

Objectives: Via peer-to-peer interaction and demonstration, this video will

• Define/describe the following terms: solid, polyhedron (face, edge, vertex), cylinder, prism
• Address a major solid misconception: prisms are not cylinders (In fact, prisms are special cases of cylinders.)
• Present characteristics of polyhedron (faces, edges, vertices)
• Describe the relationship between faces, edges, vertices (Euler's formula: V-E+F=2)
