Dancing Corn Thanksgiving Science Activity for FallMaterials

  • Tray or dish
  • A tall jar or glass
  • Popping corn
  • Baking soda
  • Vinegar
  • Water
  • Spoon

Directions

  1. Put a tray or dish under your jar. 
  2. Fill your jar with 2 cups of water. 
  3. Then you want to add a couple tablespoons of baking soda to the water. Stir to dissolve the baking soda as much as possible. Talk about what dissolves and what doesn’t. This could lead to a fun side activity testing different solids to see if they dissolve in water.
  4. Add corn kernels to the water and baking soda. Do the corn kernels sink or float. Ask questions along the way!
  5. Now here comes the fun part of our dancing corn science activity. I would suggest adding the vinegar slowly. I filled a small party cup with vinegar. 
  6. Before you talk about what’s happening with the dancing corn, ask a few questions to get your kids talking about what they see happening. The secret to the magic dancing corn is the baking soda and vinegar chemical reaction. The gas produced when the two mix produces carbon dioxide. The carbon dioxide bubbles left the corn, but then it falls back down!
  7. You can stir it if you like or you can just observe it as it is! The dancing corn lasted for a good half hour but slowed down along the way as the chemical reaction faded away.
