  • Do this “Mass Relationships in Chemical Reactions ” lab. 
  • Or try the “Double Displacement Reactions” lab. 
  • “Chemical Reactions of Metals in Solutions” is a virtual lab that uses this “Metals in Aqueous Solutions” animation. 
  • Try this “Combustion Demo” (doc) that uses isopropyl alcohol, a 2 liter soda bottle, and a wooden splint.
  • Have students explore the chemical reactions in a hotpack with “Make a Hotpack” (doc).
  • Flinn Scientific, Inc.’s “The Foating Tin Sponge” (pdf) demonstrates a single replacement reaction as well as an oxidation reduction reaction and the activity series of metals.
