YouTube Shorts are 60-second vertical aspect ratio videos that are meant for cell phone viewing. Since they are shorter and easier for students to access than traditional YouTube videos, Josh Kenney has started creating more of them for his blended chemistry class. Check out some of his tips for creating effective chemistry tutorials with YouTube Shorts.

Have you seen the "salting-out effect"? This interesting demonstration shows a separation of two layers in a solution of water and an organic solvent by adding an ionic salt. Although this concept has important applications in organic chemistry and biochemistry, it can also be visually stunning and engaging for audiences. Read on to learn how to incorporate this demonstration into your chemistry lessons.
