Unit Cells and Layer Sequences using Dimpled Packaging
Dean Campbell | Sun, 10/01/2023 - 09:07
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.
Photochemistry and Pinhole Photography: an Interdisciplinary Experiment
In this Activity, students use an oatmeal canister to make a pinhole camera, load it with black and white photographic paper, and create a paper negative using the camera. This interdisciplinary Activity combines chemistry and art.
