First, we put citric acid into our "stomach" to stand in for digestive juices. Then we added sodium bicarbonate to stand in for food. Next, we added brown food colouring to stand in for digestive enzymes.
Then we stood back and watched the "food" be digested by the acid and passed along to the "intestines."

Thanks go to the student who brought this neat experiment in to do with the class. We enjoyed it!
Fantastic! I think each and every person involved in this experiment will know about digestion following this visual experience. Thank you Miss Fuller for your openness to the ideas and sharing families bring to your class.
