1. The document discusses separating dry mixtures through sifting or sieving. Sifting and sieving involve using a strainer or screen to separate particles by size, with larger particles remaining on top and smaller particles passing through. 2. An example activity involves sifting mixtures like flour, sugar, and rice to separate them using a strainer. Sifting and sieving can separate many types of dry mixtures. 3. Sifting is defined as using a sorting device with screens to separate coarse and fine particles in mixtures like flour by breaking up lumps. Sieving separates bigger dry mixtures like sand and gravel.
