Talking Points

• What is a volcano?
  "A volcano is like a mountain that can erupt and spew out hot lava."
• Why does the volcano erupt?
  "When we mix baking soda and vinegar, it creates a chemical reaction that makes bubbles and causes the eruption."
• What is the role of food coloring?
  "The food coloring makes our eruption colorful and fun to watch!"
• What happens when we add dish soap?
  "The dish soap helps create foam and bubbles in our eruption."
• Why do we use a tray or container?
