Digestive System — It All Starts in the Mouth!
To start off our unit on the digestive system, I had the kids look at a diagram and write down all the parts of the digestive system. That was the first section of the pack I made (more about that below). Then we took a closer look at the mouth.
We did these activities over the course of several days:
I asked the kids what the mouth’s role is in the digestive system. They quickly guessed chewing, but couldn’t go into much more detail than that.
We looked at the role of our teeth… and learned about the different types of teeth we have. We made “dental impressions” with Model Magic, modeling clay. We looked at the surface area created by our different types of teeth.
Did you know that everyone has a unique dental impression? We compared impressions — and it was super easy to figure out DD’s impression (she lost her front tooth!!)
I asked them to bite into a carrot and asked them where they put the carrot (in their two front teeth of course except for DD who has no front teeth at the moment!! Yes, she lost the other one! LOL! She enjoyed using our teeth puppet instead! Boy, you should have heard the sound effects… it sounded like a bear going after that carrot. It still makes me chuckle thinking about it!)
- Incisors: Cut or slice food
- Canines – tear or rip food. Naturally, we had to look closely at Boomer’s impressive canines!
- Premolars and Molars – grind the food.
