Prima-donna snowman Chef Kelvin provides the chief ingredients in this playful look at snowflake-formation. As host Snow White narrates, Chef Kelvin warms himself, evaporates and forms into a cloud, reserving some water vapor for the big event, deposition, or the transformation of water vapor directly into ice, which makes snow crystals. As the studio audience oohs and aahs, playful visuals mix the cooking-show motif with science to great effect—one highlight is the image of Chef Kelvin in cloud form as a particle accelerator for the deposition process. Complete with a commercial break and outtakes, this show’s as packed with information as a good hard snowball. (Informational picture book. 7-10)
