Building Molecular Models of Covalent Compounds Using Molecular Model Sets
Lab for Chemistry or Physical Science Students in Grades 9-12
Justification for the lab:
Bonding is a very abstract concept and can be very difficult to understand for some students. There is no clear-cut method to determine the type of bond formed, or the degree of polarity of a bond. Students often think of molecules as being two-dimensional since they most often see them drawn on paper. Using molecular model sets to build molecules is an excellent way to reinforce the three-dimensional nature of molecules. By building models, students also quickly realize that molecules can be polar or nonpolar based on their shape.
To build three-dimensional models of simple covalent molecules and to predict the polarity of the molecule from its shape.
What is included in this product?
--Four page student handout
