In this activity (on pages 4-5), learners make fake snow by adding water to the super-absorbant chemical from diapers, sodium polyacrylate. Different types of fake snow can be made by varying the amount of water added to the chemical. Learners can observe the different combinations with a magnifying glass. Some background chemistry is included in the "Where's the Chemistry?" box on page 5. The introductory paragraphs on page 4 explain that this fake snow is not the same as the stuff in the movies, which is made from hexylene glycol liquid in a snow machine.
