The document provides a science practice quiz that tests students' abilities to classify materials by state of matter, identify types of mixtures as solid-solid, solid-liquid, or liquid-liquid, and determine the best separation technique to use for different mixtures. Students are asked to organize examples like wood, paper, milk, oxygen into solid, liquid, or gas categories and identify mixtures as solid-solid, solid-liquid, or liquid-liquid. They are also asked to determine whether a magnet, sieve, water, or air would be best to separate mixtures like sand and metal fillings.
