This activity promotes development and learning by encouraging children to:

  • Explore how properties change and objects can move in space.
  • Refine the use of what, why, when, where, and how questions by asking them sequentially.
  • Independently develop hypotheses, make predictions, plan investigations, and draw conclusions.


  • A clear cup or jar
  • Raisins
  • Clear, well-carbonated soda e.g., seltzer water, Sprite, etc.


  1. Open and pour carbonated soda into a clear cup or jar.
  2. Add raisins to the cup or jar.
