Using Molecular Models to Teach Chemistry

Molecular model kits are indispensible for teaching some of the key concepts of chemistry. Manipulating models helps pupils access the invisible world of atoms and molecules.

The resources below, which include lesson plans and worksheets, have been produced by the RSC Schoolteacher Fellow 2008-9, Anthony Hardwicke. Further examples will be added over the coming months.

Molecular model kits are fun to use and engaging for students. It is worth, however considering the implications for classroom management. The following hints and tips may help:

• Even in the best behaved classes, students often allow atoms to roll off the desk and onto the floor. This can be avoided by providing students with lids or trays to keep the atoms in.
• Always ask students to put their models down before you address the class.
• Allow a few minutes for them to break up their models at the end of the session.
• Be cautious about letting two groups pool their atoms in order to make a giant model, unless specifically instructed to - this can cause delay when it is time to pack up.
• Check that each group has the same number of atoms and bonds as they started with - students can do this.
