Carolina Phenomenon

Phenomena-driven science! Phenomena are observable, naturally occurring events that are everywhere and spark student questions and investigations. Ask students to observe the DCI-linked phenomena in the video and complete the attached student sheet prior to remote learning discussions.

Observations: Carefully watch the petri dish electrolysis video. Gather all the evidence you can from the video, and write down everything you observe.

Generate Questions: What evidence is there that a reaction is taking place? What type of reaction is this? What do the colors in the dish mean? What role do the small rods have in the reaction? Why does the color go away when the liquid in the dish is stirred?

Research (include sources):

Final Explanation: Use a written explanation, graphic, or flow chart to present your final explanation for the petri dish electrolysis.
