Description and Teaching Materials

The students would make an Indi-Gator and put a number one on one and two on the other. You would dip the first Indi-Gator into juice (don't dip the tail) and take it out. Then they would predict what will happen if you dip it into the baking soda. Repeat the above before dipping into the vinegar.

The second Indi-Gator would start with vinegar, then baking soda, and then grape juice. They should also make the predictions before each step.

They would also have a chart to record their predictions.

Teaching Notes and Tips


I will listen to discussion that the students have and the chart they have recorded their predictions on.
