Separating Mixtures Sub Plan (No Prep): Recycling Plant Challenge, Grades 5-8

Tank 7 at the Ridgeway Recycling Plant holds sand, salt, iron filings, plastic beads and water, all mixed together. Students read the plant's property table, choose a tool for each step (magnet, screen, filter, skimmer, drying pan; one is not needed), say what each step takes out and which property makes it work, then explain what would go wrong if the order changed.
