Here's another science experiment to go along with our study of the digestive system. This time we put a cracker on Norah's tongue to see her salivary glands go to work and see if she could taste the sweet taste of the enzyme called amylase in her saliva breaking down the starches in the cracker into sugars. Norah didn't really taste much sweetness with the cracker, so we plan to try this experiment with bread. Norah will chew on bread and not swallow it and hopefully, see how the bread begins to taste sweet after the saliva starts to work on it.
