Flowers & Perfume

  • Attar of Roses
    Give your sweetheart a rose for Valentine’s Day—or just buy one for yourself and try this experiment. You’ll attempt to isolate the compounds that make up its fragrance.
  • Colored Flowers
    Let them know you care with flowers. But don’t forget the chemistry twist—color them first using a classic capillary action experiment.
  • Chemically Perfect Perfume
    Take a trip around the laboratory as different components are added to a Valentine bottle in a quest for the perfect perfume.


Chocolate

  • Eat Chocolate in the Name of Science
    Need an excuse to eat more chocolate? Here it is! Try this experiment and see how your chocolate experience changes depending on temperature.
  • The Sweet Lure of Chocolate
    Drool over this site as you learn the history of chocolate and try a hands-on “tempering” activity.
  • A Calendar Year of Chemistry
    The calendar would not be complete without a Valentine’s Day video. Check out “The Chemistry of Chocolate” in this collection.

Join the professor (from the Periodic Videos from the University of Nottingham, United Kingdom) for a chat as he tells you about the chemistry of chocolate and roses, with a smashing finale.
