Describing the simple functions of the basic parts of the digestive system in humans
To get a better understanding of our digestive system and the effects on the food that we eat, we will be re-creating certain processes and carrying out different experiments.
Your digestive (say: dye-JES-tiv) system started working even before you took the first bite of your pizza. And the digestive system will be busy at work on your chewed-up lunch for the next few hours — or sometimes days, depending upon what you've eaten. This process, called digestion, allows your body to get the nutrients and energy it needs from the food you eat.
Identifying the different types of teeth in humans and their simple functions
We will learn why we have different types of teeth and the jobs that they do. We will also investigate how to keep our teeth healthy.
