Welcome, young chemists! Today we will investigate how molecules decide whether to be “polar” or “non-polar” — and why that matters in everything from dissolving sugar to the behavior of cell membranes. You will watch a crash-course video, explore an informational website to deepen your understanding, try a simulation that lets you experiment with molecular shape and electronegativity, and finish with a fun review game to test your detective skills. Grab your lab notebooks and get ready to uncov
