Is saliva involved in digestion?

This activity has been carried out in English as part of the curriculum of Biology and 
Geology of 3rd ESO. In this laboratory activity, the students had to create an hypothesis in order to understand the reaction that occurs when the starch comes in contact with the saliva and is transformed into glucose.

The students did a running-dictation: with a glossary of images of the laboratory material, the students had to choose and write the correct name of the utensils they use.
