imersion reflection

For my emersion, we are doing energy. On the second session, we did an experiment called elephant toothpaste we used hydrogen peroxide, food coloring, dishwashing liquid, and yeast. we found this small plastic bottle with a wide top. We took it and used it.

we poured the hydrogen peroxide into the bottle and the dishwashing liquid and the food coloring and then the yeast it started to form a foam and it started to shoot out the bottle. Nicole asked us to touch it and it was warm that is because of the chemical reaction producing kinetic energy.
