This is a nine station lab that explores chemical and physical changes. This lab was designed for a ninth grade physical science class but could easily be used in middle school or as an introductory chemistry lab. A list of supplies needed is included below. Experiments are small scale only needing a small amount of each chemical. Do not be dissuaded if you do not have every chemical on the list, this lab could be done with a reduced number of stations or substitutions based on what you have available. Supplies Needed:Test Tubes, Pipets, Eyedroppers, or Dropper Bottles, Beakers for waste, Rinse Bottles or Water Supply, Milk,Lemon Juice (Vinegar can substitute),Corn Starch, Iodine, Foil,Toothpicks, Styrofoam, Acetone, Sodium Hydroxide (low molarity is fine), Phenolphthlalein, Cotton Balls, Isopropyl Alcohol, Iron Filings, Copper Chloride Solution, Ammonia,Copper Sulfate Solution,Sodium Polyacrylate (Instant Snow),Epsom Salt, Candle or other heat source, Test Tube Tongs
