Tips

  • Have a designated place in the classroom where students store their Predictions and Planning Tool so they can easily refer back to their ideas at the end of the lesson.

Expect many students to make the right predictions for the wrong reasons. Note in particular whether they say that changes in the mass of the soda water indicate that atoms are moving.

Students can discuss other situations where bubbles form and leave liquids, such as the bubbles that form when water is boiled, when baking powder or Alka-Seltzer are dissolved in water, or when vinegar and baking soda are mixed. How do they see these phenomena as similar to or different from soda water fizzing? What do they see as happening to mass?
