Materials

Teacher materials

  • 1 liter ice water (cold water containing ice cubes works best)
  • 1 liter warm tap water
  • 1 liter room temperature water
  • Bubble solution (purchased) or dishwashing liquid and glycerin (to make bubble solution)
  • 1 tea candle and matches (a hotplate, warming tray, or warm towel also will work)
  • Transparency of "My Observations" worksheet

Materials per group of four students 

  • Bottom half of one aluminum soft drink can (see Teacher Setup below)
  • Shallow bowl containing bubble solution
  • Wide-mouth plastic cup (9-oz size) half-filled with warm tap water 
  • Wide-mouth plastic cup (9-oz size) half-filled with ice water (include a few ice cubes)
  • Wide-mouth plastic cup (9-oz size) half-filled with room temperature water
  • Red crayon or marker
  • Blue crayon or marker
  • 4 pairs of safety goggles 
  • 4 copies of "My Observations" worksheet

Setup

  1. Prepare aluminum soft drink cans: Cut each can approximately in half (scissors work well) and save the bottom section. You will need one bottom section per group of students. (Discard or recycle the top halves.) Be sure that the cut edges of the can are smooth or covered with tape, so students do not injure themselves.
  2. Prepare bubble solution: If you do not have commercial bubble solution, you can easily make your own by mixing together 1 gallon of water, 1 cup of dishwashing liquid, and ¼ cup of glycerin (from the drugstore).
