Unit Cells and Layer Sequences using Dimpled Packaging

Regularly dimpled trays such as those used in food packaging can be used to represent layers of atoms in solid structures. For example, the square array of dimples in transparent plastic mini quiche trays can be used to depict layers within cubic or tetragonal unit cells. Multiple solid structures and ways to represent those structures are described. 

Paper Snowflakes to Model Flat Symmetrical Molecules

Flat, symmetrical molecules can be modeled by folding a sheet of paper, cutting patterns into the folded structure, and unfolding to produce the flat paper models. The finished models resemble paper snowflakes, but have a variety of rotational symmetries. Template patterns for several molecules are available for download in the Supporting Information.

A Multi-Colored Equilibrium Experiment

Solutions of copper (II) dissolved in acetone are easy to prepare, and can display orange, yellow, green, and blue color depending upon conditions. Such solutions allow for a variety of demonstrations and experiments that illustrate principles of chemical equilibrium.
