Teach The Science Of Electroplating Caswell Science Plating Kits Tin Plating System Electroplating is an interesting and exciting science experiment for kids and adults alike. Invented in the early 1800's, electroplating covers science fundamentals such as chemistry, electricity and mathematics. Our Science Plating Kits support NGSS standards at the Grade Five level in the "Matter and Its Interactions" topic, as well as many others. Our Tin Science Plating Kit can be used to plate tin over steel, iron, tin, pot metal, zinc as well as copper, brass & bronze. Our Tin Science Plating Kit contains: 1 x One Pint Plastic Beaker One Pint Tin Plating Solution Two Tin Anodes 4.5V, 300ma DC Power Supply All required wires Wooden Tank Bar Bare Copper Wire To Hang Parts Instruction Sheet In addition to our kit, you will need: Nitrile or Latex Gloves Eye Protection Beaker of Water for rinsing Cleaning agent (we recommend dish soap and hot water or Simple Green cleaner) The kit can be used multiple times.
