TikTok and YouTube Shorts are video sharing platforms for short-form, vertical aspect videos. Both of these services are growing more quickly in popularity compared to more traditional video formats. Josh Kenney shares some of the ways that he is using short-form videos in his chemistry class and shares a free resource (an exam review worksheet that links to a YouTube Shorts playlist through a QR code).

Egg cartons and small objects such as milk jug caps or plastic eggs can be used to illustrate chemical concepts. The egg cartons can be cut into trays to represent atoms or to represent energy levels associated with atomic orbitals. The plastic caps or eggs distributed among the dimples of the trays can be used to represent electrons or pairs of electrons.

Find out how laboratory activities can be used as the starting point for scientific model development rather than as the endpoint, or verification, of concepts presented in lecture. This post deals with density.

Polystyrene foam sticks with a square or rectangular profile will not fit into a round target hole (e.g., the opening of a soda bottle) at room temperature. However, they do contract sufficiently in contact with liquid nitrogen to fit into the hole and produce a simple demonstration of Charles’s Law. Many other polymer foams do not shrink under these conditions, but still provide opportunities to discuss and explore their structure and chemistry.
